    Should you be sleepmaxxing to boost health and happiness?

    If you’ve been on TikTok lately, you know it’s hard to avoid countless influencers touting a concept called sleepmaxxing. Their posts provide tips and tricks to get longer, better, and more restorative sleep. And why not? Sleep is considered a pillar of good health and is related to everything from brain health to cardiovascular health, and even diabetes.

    But what exactly is sleepmaxxing? And how likely is it to deliver on claims of amped-up energy, a boost to the immune system, reducing stress levels, and improving your mood?

    What is sleepmaxxing?

    Depending on which social media platform you happen to be looking at, the recommended strategies for maximizing sleep differ. Tips include:

    • taping your mouth shut while sleeping
    • not drinking anything during the two hours before bedtime
    • a cold room temperature
    • a dark bedroom
    • using a white noise machine
    • not setting a morning alarm
    • showering one hour before bedtime
    • eliminating caffeine
    • eating kiwis before going to bed
    • taking magnesium and melatonin
    • using weighted blankets
    • getting 30 minutes of sunlight every day
    • meditating daily for 30 minutes.

    Does any research support sleepmaxxing?

    A thorough search through PubMed, PsycNet, and Google Scholar reveals zero results for the terms “sleepmaxx” and “sleepmaxxing.” But wait — this certainly doesn’t mean that some influencer-recommended strategies are not evidence-based, just that the concept of sleepmaxxing, as a defined package, has not been scientifically studied. But yes, some of the strategies — including one uncomfortable, though popular, choice — lack evidence.

    Can mouth-taping improve your sleep?

    TikTok users have claimed that taping your mouth while you sleep has benefits, such as reducing snoring and improving bad breath. A team from the department of otolaryngology at George Washington University was prompted by all of the social media buzz on the topic to review research on the impact of nocturnal mouth taping. Spoiler alert: the authors note that most TikTok mouth-taping claims aren’t supported by research.

    If you do snore, it’s important to discuss this with your medical team. Even if taping your mouth reduces your snoring, it can’t effectively treat a potential underlying cause of the snoring, such as allergies, asthma, or sleep apnea.

    Sleepmaxxing or basic sleep hygiene?

    Many strategies recommended by sleepmaxxers are essentially what sleep experts prescribe as good sleep hygiene, which has plenty of research backing its value. Common components of sleep hygiene are decreasing caffeine and alcohol consumption, increasing physical activity, sleep timing, reducing evening light exposure, limiting daytime naps, and having a cool bedroom.

    While tips like these help many people enjoy restful sleep, those who have an insomnia disorder will need more help, as described below.

    Melatonin, early bedtime, weighted blankets, and — kiwi fruit?

    Other strategies suggested by sleepmaxxers are based on limited scientific data. For example:

    • Taking melatonin is recommended by the American Academy of Sleep Medicine to treat circadian rhythm disorders such as jet lag. But it’s not recommended for insufficient sleep, poor sleep quality, or difficulty with falling asleep or staying asleep.
    • Is it healthier to be asleep by 10 p.m.? One video that garnered more than a million views claims it is. While it is important to maximize morning sunlight exposure and minimize evening light exposure to regulate circadian rhythms, there is such variability in how much sleep someone requires and individual chronotypes (not to mention varying personal and professional responsibilities!) that it is difficult to state there is an ideal bedtime for everyone.
    • While intriguing research has been done on weighted blankets, there is no convincing evidence that they are truly effective for the general adult population.
    • Overall, it’s important to be cautious about the impact of the placebo effect on how someone sleeps. An analysis of more than 30 studies showed that roughly 64% of the drug response for a sleep medication in insomnia patients could be due to the placebo effect. A key takeaway is that studies that are not randomized controlled trials — such as this small study on 24 people suggesting that kiwi fruit may improve sleep — should be interpreted with a grain of salt.

    Could you have orthosomnia?

    The expectation of flawless sleep, night in and night out, is an unrealistic goal. Orthosomnia is a term that describes an unhealthy pursuit of perfect sleep. The pressure to get perfect sleep is embedded in the sleepmaxxing culture.

    With more and more people able to access daily data about their sleep and other health metrics through consumer wearables, even a person who is objectively sleeping well can become unnecessarily concerned with optimizing their sleep. While prioritizing restful sleep is commendable, setting perfection as your goal is problematic. Even good sleepers vary from night to night, experiencing less than desirable sleep a couple of times per week.

    It is also noteworthy that some of the most widely viewed recommendations on TikTok are not supported by scientific evidence.

    Do you really need to fix your sleep?

    A good first step is to understand whether or not there is anything that you need to fix! Consider tracking your sleep for a few weeks using a sleep diary, and pair this data with a consumer wearable (such as a Fitbit or Apple Watch). Both imperfectly capture sleep data when compared to the gold-standard tool sleep experts use (polysomnography, or a sleep study). However, combining the information can give you a reasonable assessment of your sleep status.

    Regularly getting restful sleep can indeed boost health and mood. And all of us can benefit from following basic sleep hygiene tips. But if it takes you 30 minutes or more to fall asleep, or if you are up for 30 minutes or more in the middle of the night, and this happens three or more times per week, then consider reaching out to your health care team to seek further evaluation.

    There are effective, nonmedication treatments that are proven to help you sleep better. One example is cognitive behavioral therapy for insomnia, which can dramatically improve insomnia symptoms in a matter of weeks.

  • New surgery for benign prostate hyperplasia provides long-lasting benefits

    New surgery for benign prostate hyperplasia provides long-lasting benefits

    A row of urinals in a public restroom, with light-colored dividers between them.

    Most men over 50 will develop an enlarged prostate. Also called benign prostatic hyperplasia (BPH), this bothersome condition makes it hard to urinate and can eventually lead to other problems, such as infections, kidney stones, and bladder damage, if left untreated. Many different BPH therapies are available, including medications and various types of surgery.

    One of the newer surgical options, called aquablation, trims excess prostate tissues with highly pressurized jets of saline. Doctors perform aquablation in the operating room while looking at the prostate gland on an ultrasound machine. Patients are put under general anesthesia, so they don’t feel any pain during the procedure.

    Men typically have to urinate through a catheter for about 24 hours after surgery until swelling of the urethra (the tube through which urine flows out of the bladder) subsides. Aquablation is gaining in popularity — in part because, unlike other more traditional BPH treatments, it can preserve normal ejaculation.

    In September, researchers published a study showing that improvements in urinary function from aquablation were still holding up after five years.

    Results of data analysis

    The study assessed long-term data from two clinical trials. The first, called the WATER trial (for Waterjet Ablation Therapy for Endoscopic Resection of Prostate Tissue) launched in 2015 and enrolled 116 men with prostates ranging up to 80 cubic centimeters. The second trial, WATER II, launched in 2017 and enrolled 101 men with prostates ranging between 80 and 150 cubic centimeters. (Normal prostates range from 25 to 30 cubic centimeters in size.) Enrolled patients had a median age of 66 in the WATER study and 68 in WATER II. In addition, 92% of men in the WATER trial were sexually active, as were 75% of the men in WATER II.

    Both clinical trials used the so-called International Prostate Symptom Score (IPSS) to measure treatment-related improvements in urinary functioning and quality of life. Calculated based on how patients rate their symptoms on a standardized questionnaire, IPSS scores fall into three categories: mild symptom scores range from 1 to 7; intermediate symptom scores range from 8 to 18; and scores greater than 19 indicate severe symptoms.

    When they first enrolled in the trials, men in the WATER and WATER II studies reported average IPSS scores of 22.9 and 23.3 respectively. Five years later, the average respective scores were much lower: 7.0 and 6.8. The average length of hospital stay was 1.4 days in the WATER group and 1.6 days for the WATER II group. Only 1% of men were taking BPH medications after five years, and fewer than 5% had been surgically re-treated.

    Another randomized control trial, WATER III, is currently underway in Europe. That trial compares aquablation with a more established type of BPH surgery, prostate enucleation, which uses a laser to remove obstructing tissues. Six-month data reported in 2023 showed that men in either group had comparable symptom improvements.

    However, 98% of men in the prostate enucleation group had ejaculatory dysfunction. That side effect is caused by damage to delicate tissues around the bladder neck that propel semen out of the body. Semen therefore flows back into the bladder, a condition called retrograde ejaculation. None of the men in the aquablation group reported ejaculatory problems.

    A word of caution

    Aquablation can result in extended bleeding, cautions Dr. Heidi Rayala, an assistant professor of urology at Harvard Medical School and a member of the Harvard Medical School Guide to Prostate Diseases advisory board. That’s because unlike other types of surgery for BPH, including prostate enucleation, aquablation doesn’t cauterize tissues with heat. “I tell my patients to expect some blood in the urine for about four to six weeks after the procedure,” Dr. Rayala said.

    Moreover, aquablation may be unsuitable for some men who take blood thinners to prevent blood from clotting, according to Dr. Rayala. Appropriate candidates for the surgery must be able to “safely discontinue anticoagulant medications during post-operative healing, given the bleeding risk,” Dr. Rayala said. Still, aquablation is an excellent option for most men, Dr. Rayala said, especially those with medium to large prostates “who want a durable solution with a lower risk of sexual side effects.”

    “These early results are encouraging, but limited by a relatively small number of patients,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases. “Further evidence with a significantly larger number of patients and longer follow-up will help to support this new method of reducing prostate tissue as an important treatment option.”

  • Celiac disease: Exploring four myths

    Celiac disease: Exploring four myths

    Gluten-free bread & bagels with 12 appetizing toppings like avocado & olives, hummus & chickpeas, sliced hardboiled eggs & greens; concept is celiac disease

    Celiac disease is a digestive and immune disorder that can keep the body from absorbing necessary nutrients. “Our conception and awareness of celiac disease has evolved over the past few decades, but there are still aspects that remain poorly understood,” says Dr. Ciaran Kelly, medical director of the Celiac Center at Beth Israel Deaconess Medical Center and professor of medicine at Harvard Medical School.

    Perhaps not surprisingly, misconceptions are widespread among the general public. One example? Many people assume that everyone who has celiac disease is plagued by abdominal pain, bloating, or diarrhea. But actually, many adults newly diagnosed with this inherited gluten intolerance don’t have these symptoms.

    What’s more, gluten — the sticky protein found in grains such as wheat, barley, and rye — can cause gastrointestinal distress and other symptoms in people who don’t have celiac disease. Read on for a deeper dive into four myths and facts about celiac disease and related digestive conditions.

    Myth # 1: Celiac disease is usually diagnosed at a young age

    Not typically. While celiac disease can develop any time after a baby’s first exposure to gluten, it’s usually diagnosed much later in life. According to the National Celiac Association, the average age of diagnosis is between 46 and 56. Around 25% of people are diagnosed after age 60.

    Celiac disease is slightly more common in women and among people with other autoimmune conditions, including type 1 diabetes, Hashimoto’s thyroiditis (a common cause of low thyroid levels), and dermatitis herpetiformis (a rare condition marked by an itchy, blistering rash).

    “We don’t know why some people go from being susceptible to actually having celiac disease,” says Dr. Kelly. The prevailing theory is that some sort of physical or emotional stress — such as a viral infection, surgery, or anxiety from a stressful life event — may “flip the switch” and cause the disease to appear, he says. “Increasing numbers of people are being diagnosed at midlife and older, often after they’re found to have conditions such as anemia or osteoporosis caused by nutrient deficiencies,” says Dr. Kelly.

    Myth #2: Celiac disease only affects the gut

    When people have celiac disease, eating gluten triggers an immune system attack that can ravage the lining of the small intestine. A healthy small intestine is lined with fingerlike projections, called villi, that absorb nutrients. In celiac disease, the immune system attacks the villi, causing them to flatten and become inflamed — and thus unable to adequately absorb nutrients.

    While gastrointestinal problems can occur, they aren’t always present. In fact, celiac disease can present with many different symptoms that affect the nervous, endocrine, and skeletal systems. A few examples are brain fog, changes in menstrual periods, or muscle and joint pain.

    Myth # 3: Celiac disease versus gluten intolerance

    If you feel sick after eating gluten, you probably have celiac disease, right? Actually, that may not be true. Some people have non-celiac gluten sensitivity (also called gluten intolerance), which can cause uncomfortable digestive symptoms after eating gluten. But gluten intolerance differs from celiac disease.

    • Celiac disease is diagnosed with blood tests that look for specific antibodies. If antibodies are present, a definitive diagnosis requires an intestinal biopsy to look for signs of damage that characterize the condition.
    • Non-celiac gluten sensitivity does not trigger antibodies or cause intestinal damage. Yet some people with this problem say they also experience brain fog, trouble concentrating, muscle aches and pain, and fatigue after eating gluten-containing foods.

    “Non-celiac gluten sensitivity appears to be a real phenomenon, but it’s not well defined,” says Dr. Kelly. It’s unclear whether people experiencing it are intolerant to gluten or to something else in gluten-containing foods.

    • One possibility is sugarlike molecules known as FODMAPs, which are found in many foods — including wheat. Short for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, gas and bloating can occur when gut bacteria feed on FODMAPs.
    • Another possibility is an allergy to wheat, which can cause symptoms such as swelling, itching, or irritation of the mouth and throat after eating wheat. Other symptoms include a skin rash, stuffy nose, and headache, as well as cramps, nausea, and vomiting. Some people may develop a life-threating allergic reaction known as anaphylaxis.

    Myth #4: A gluten-free diet always relieves the symptoms and signs of celiac disease

    The sole treatment for celiac disease — adopting a diet that avoids all gluten-containing foods — doesn’t always help. This problem is known as nonresponsive celiac disease.

    “About 20% of people with celiac disease have ongoing symptoms, despite their best efforts to stick to a gluten-free diet,” says Dr. Kelly. Others have intermittent signs and symptoms, particularly when they are accidentally exposed to gluten. Accidental exposures often happen when people eat prepared or restaurant foods that claim to be gluten-free but are not. Cross contamination with gluten-containing foods is another potential route.

    Potential solutions to nonresponsive celiac disease are being studied. Three promising approaches are:

    • Enzymes that break down gluten, which people could take alongside gluten-containing foods. “It’s a similar concept to the lactase pills taken by people who are lactose intolerant to help them digest dairy products,” says Dr. Kelly.
    • Dampening the immune response to gluten by inhibiting an enzyme called tissue transglutaminase that makes gluten more potent as an antigen.
    • Reprogramming the immune response to prevent the body from reacting to gluten.

  • Measles is making a comeback: Can we stop it?

    Measles is making a comeback: Can we stop it?

    A road sign with the words "Measles Outbreak" in red and black against a wavy white and rusted steel background

    Has the recent news about measles outbreaks in the US surprised you? Didn’t it seem like we were done with measles?

    In the US, widespread vaccination halted the ongoing spread of measles more than 20 years ago, a major public health achievement. Before an effective vaccine was developed in the 1960s, nearly every child in the US got measles. Complications like measles-related pneumonia or hearing loss were common, and 400 to 500 people died each year.

    As I write this, there have been 884 confirmed cases in 29 states, mostly among children. The biggest outbreak is in west Texas, where 64 people have been hospitalized and two unvaccinated school-age children recently died, the first measles deaths in the US since 2015. Officials in New Mexico have also reported a measles-related death.

    Can we prevent these tragedies?

    Measles outbreaks are highly preventable. It’s estimated that when 95% of people in a community are vaccinated, both those individuals and others in their community are protected against measles.

    But nationally, measles vaccination rates among school-age kids fell from 95% in 2019 to 92% in 2023. Within Texas, the kindergarten vaccination rates have dipped below 95% in about half of all state counties. In the community at the center of the west Texas outbreak, the reported rate is 82%. Declining vaccination rates are common in other parts of the US, too, and that leaves many people vulnerable to measles infections.

    Only 2% of the recent cases in the US involved people known to be fully vaccinated. The rest were either unvaccinated or had unknown vaccine status (97%), or they had received only one of the two vaccine doses (1%).

    What to know about measles

    As measles outbreaks occur within more communities, it’s important to understand why this happens — and how to stop it. Here are seven things to know about measles.

    The measles virus is highly contagious

    Several communities have suffered outbreaks in recent years. The measles virus readily spreads from person to person through the air we breathe. It can linger in the air for hours after a sneeze or cough. Estimates suggest nine out of 10 nonimmune people exposed to measles will become infected. Measles is far more contagious than the flu, COVID-19, or even Ebola.

    Early diagnosis is challenging

    It usually takes seven to 14 days for symptoms to show up once a person gets infected. Common early symptoms — fever, cough, runny nose — are similar to other viral infections such as colds or flu. A few days into the illness, painless, tiny white spots in the mouth (called Koplik spots) appear. But they’re easy to miss, and are absent in many cases. A day or two later, a distinctive skin rash develops.

    Unfortunately, a person with measles is highly contagious for days before the Koplik spots or skin rash appear. Very often, others have been exposed by the time measles is diagnosed and precautions are taken.

    Measles can be serious and even fatal

    Measles is not just another cold. A host of complications can develop, including

    • brain inflammation (encephalitis), which can lead to seizures, hearing loss, or intellectual disability
    • pneumonia
    • eye inflammation (and occasionally, vision loss)
    • poor pregnancy outcomes, such as miscarriage
    • subacute sclerosing panencephalitis (SSPE), a rare and lethal disease of the brain that can develop years after the initial measles infection.

    Complications are most common among children under age 5, adults over age 20, pregnant women, and people with an impaired immune system. Measles is fatal in up to three of every 1,000 cases.

    During the latest outbreaks, 94 cases —nearly one in nine — have required hospitalization.

    Getting measles may suppress your immune system

    When you get sick from a viral or bacterial infection, antibodies created by your immune system will later recognize and help mount a defense against these intruders. In 2019, a study at Harvard Medical School (HMS) found that the measles virus may wipe out up to three-quarters of antibodies protecting against viruses or bacteria that a child was previously immune to — anything from strains of the flu to herpesvirus to bacteria that cause pneumonia and skin infections.

    “If your child gets the measles and then gets pneumonia two years later, you wouldn’t necessarily tie the two together. The symptoms of measles itself may be only the tip of the iceberg,” said the study’s first author, Dr. Michael Mina, who was a postdoctoral researcher in the laboratory of geneticist Stephen Elledge at HMS and Brigham and Women’s Hospital at the time of the study.

    In this video, Mina and Elledge discuss their findings.

    Vaccination is highly effective

    Two doses of the current vaccine provide 97% protection — much higher than most other vaccines.  Rarely, a person gets measles despite being fully vaccinated. When that happens, the disease tends to be milder and less likely to spread to others.

    The measles vaccine is safe

     The safety profile of the measles vaccine is excellent. Common side effects include temporary soreness in the arm, low-grade fever, and muscle pain, as is true for most vaccinations. A suggestion that measles or other vaccines cause autism has been convincingly discredited. However, this often-repeated misinformation has contributed to significant vaccine hesitancy and falling rates of vaccination.

    Ways to protect yourself from measles infection

    • Vaccination. Usually, children are given the first dose around age 1 and the second between ages 4 and 6 as part of the Measles-Mumps-Rubella (MMR) vaccine. If a child — or adult — hasn’t been vaccinated, they can have these doses later.

      If you were born after 1957 and received a measles vaccination before 1968, consider getting revaccinated or tested for measles antibodies (see below). The vaccine given before 1968 was less effective than later versions. And before 1957, most people became immune after having measles, although this immunity can wane.

    • Isolation. To limit spread, everyone diagnosed with measles and anyone who might be infected should avoid close contact with others until four days after the rash resolves.
    • Mask-wearing by people with measles can help prevent spread to others. Household members or other close contacts should also wear a mask to avoid getting it.
    • Frequent handwashing helps keep the virus from spreading.
    • Testing. If you aren’t sure about your measles vaccination history or whether you may be vulnerable to infection, consider having a blood test to find out if you’re immune to measles. Memories about past vaccinations can be unreliable, especially if decades have gone by, and immunity can wane.
    • Pre-travel planning. If you are headed to a place where measles is common, make sure you are up to date with vaccinations.

    The bottom line

    While news about measles in recent months may have been a surprise, it’s also alarming. Experts warn that the number of cases (and possibly deaths) are likely to increase. And due to falling vaccination rates, outbreaks are bound to keep occurring. One study estimates that between nine and 15 million children in the US could be susceptible to measles.

    But there’s also good news: we know that measles outbreaks can be contained and the disease itself can be eliminated. Learn how to protect yourself and your family. Engage respectfully with people who are vaccine hesitant: share what you’ve learned from reliable sources about the disease, especially about the well-established safety of vaccination.

  • What is prostatitis and how is it treated?

    What is prostatitis and how is it treated?

    Illustration showing a normal prostate gland on the left and a prostate with prostatitis on the right, with the enlarged gland causing a compressed urethra.

    Prostatitis, or inflammation of the prostate, is more common than you might think — it accounts for roughly two million doctor visits every year. The troubling symptoms include burning or painful urination, an urgent need to go (especially at night), painful ejaculations, and also pain in the lower back and perineum (the space between the scrotum and anus).

    Prostatitis overview

    There are four general categories of prostatitis:

    Acute bacterial prostatitis comes on suddenly and is often caused by infections with bacteria such as Escherichia coli that normally live in the colon. Men can suffer muscle aches, fever, and blood in semen or urine, as well as urogenital symptoms. Acute inflammation can cause the prostate to swell and block urinary outflow from the bladder. A complete blockage is a medical emergency that requires immediate treatment. Depending on symptom severity, hospitalization may be necessary.

    Chronic bacterial prostatitis results from milder infections that sometimes linger for months. It occurs more often in older men and the symptoms typically wax and wane in severity, sometimes becoming barely noticeable.

    Chronic nonbacterial prostatitis, also called chronic pelvic pain syndrome (CPPS), is the most common type. CPPS can be triggered by stress, urinary tract infections, or physical trauma causing inflammation or nerve damage in the genitourinary area. In some men, the cause is never identified. CPPS can affect the entire pelvic floor, meaning all the muscles, nerves, and tissues that support organs involved in bowel, bladder, and sexual functioning.

    Asymptomatic inflammatory prostatitis is diagnosed when doctors detect white blood cells in prostate tissues or secretions in men being evaluated for other conditions. It generally requires no treatment.

    Both acute and chronic bacterial prostatitis can cause blood levels of prostate-specific antigen (PSA) to spike. This can be alarming, since high PSA is also indicative of prostate cancer. But if a man has prostatitis, then that condition — and not prostate cancer — may very well be the reason for the rise in PSA.

    Prostatitis treatments

    Fortunately, research advances are leading to some encouraging developments for men suffering from this condition.

    Antibiotics called fluoroquinolones are effective treatments for acute and chronic bacterial prostatitis. A four-to six-week course of the drugs typically does the trick. However, bacterial resistance to fluoroquinolones is a growing problem. An older drug called fosfomycin can help if other drugs stop working. PSA levels will decline with treatment, although that process may take three to six months.

    CPPS is treated in other ways. Since it is not caused by a bacterial infection, CPPS will not respond to antibiotics. Medical treatments include nonsteroidal anti-inflammatory drugs such as ibuprofen, alpha blockers including tamsulosin (Flomax) that loosen tight muscles in the prostate and bladder neck, and drugs called PDEF inhibitors such as tadalafil (Cialis) that improve blood flow to the prostate.

    Specialized types of physical therapy can provide some relief. One method called trigger point therapy, for instance, targets tender areas in muscles that tighten up and spasm. With another method called myofascial release, physical therapists can reduce tension in the connective tissues surrounding muscles and organs. Men should avoid Kegel exercises, however, which can tighten the pelvic floor and cause worsening symptoms.

    Acupuncture has shown promise in clinical trials. One study published in 2023 showed significant improvements in CPPS symptoms lasting up to six months after the acupuncture treatments were finished. Mounting evidence suggest that CPPS should be treated with holistic strategies that also consider psychological factors.

    Men with CPPS often suffer from depression, anxiety, and other mental health issues that can exacerbate pain perception. Techniques such as mindfulness and cognitive behavioral therapy for CPPS can help CPPS sufferers develop effective coping strategies.

    Comment

    “An accurate diagnosis is important given differences in how each of the four categories of prostatitis is treated,” said Dr. Boris Gershman, a urologist at Beth Israel Deaconess Medical Center and assistant professor of surgery at Harvard Medical School. PSA should also be retested after treating bacterial forms of prostatitis, Dr. Gershman added, to ensure that the levels go back to normal. If the PSA stays elevated after antibiotic treatment, or if abnormal levels are detected in men with nonbacterial prostatitis, then the PSA “should be evaluated in accordance with standard diagnostic approaches,” Dr. Gershman said.

  • A low-tech school vacation: Keeping kids busy and happy without screens

    A low-tech school vacation: Keeping kids busy and happy without screens

    Father, daughter, and son playing soccer on the grass in a park;

    School vacation coming up? Wondering how to spend that time? Given how tiring holidays can be — especially for parents who are working — it’s understandable why children are often allowed to spend hours with the TV, tablet, or video games. After all, happy, quiet kids make for happy parents who can finally get stuff done — or relax.

    Except kids are spending way too much time in front of screens. According to the American Academy of Child and Adolescent Psychiatry, kids ages 8 to 12 are spending four to six hours a day watching or using screens — and tweens and teens are spending nine hours.

    Given how enticing devices and social media can be, those numbers can easily go higher during unscheduled times like weekends and school vacation. That’s why it’s good to be proactive and come up with other activities. Below are some ideas for parents and caregivers to try. These are mostly good for kids through elementary school, but tweens and teens may enjoy some of them too.

    Spending time off the screen

    Go outside. This sounds obvious, but spending time outdoors is something kids do less than they used to — and it can be really fun. If you have a yard, go out into it and play hide-and-seek or build a fort from snow or anything else that’s around. If you don’t have a yard, go to a local park or just go for a walk. A scavenger hunt up and down the block or game of I Spy may be a good enticement.

    Go to the library. Do this early on in vacation, so that your child has lots of books, puzzles, and games to pass the time. Check out as many as they allow and you can carry. Ask if a Library of Things is available at a branch near you: crafts, tools, musical instruments, birding kits, telescopes — even metal detectors may be checked out for free.

    Build a fort in the living room. Use blankets or sheets over chairs; if you have a small tent, set it up. Bring in pillows, sleeping bags, and flashlights; let the kids sleep in it at night. Let it stay up all vacation.

    Build a city in the living room. Use blocks, Legos, boxes (or anything else), and add roads, cars, people, animals, trains, and other toys. Let it stay up all vacation, and make it bigger every day.

    Getting creative off the screen

    Get creative. Go to the craft store and stock up on inexpensive supplies. Buy things like poster board, huge pieces of paper (you could use those for your city, too, to make parks, roads, and parking lots), paints, and markers. You can make a paper mural, a comic book, a story, posters, or whatever catches your child’s imagination. If you know how to knit or sew, think about teaching your child or making a simple project together.  Play music while you create.

    Read out loud. There are so many books that are fun to read aloud. When my children were younger, we read the Harry Potter series out loud, as well as the Chronicles of Narnia and books by E.B. White and Roald Dahl. Act out the voices. Have some fun.

    Have a puppet show. If you don’t have puppets, you can make some with socks — or you can hold up dolls or action figures and do the talking for them. You can make a makeshift stage by cutting out the back of a box and taping cloth (like a pillowcase) to fall over the front.

    Get out the games. There are so many that work across the ages, like checkers, chess, Uno, Connect 4, Sorry, Twister, Clue, Scrabble, or Monopoly. We forget how much fun these can be.

    Bake. You don’t have to get fancy — it’s fine to use mixes or pre-made cookie dough. There’s nothing better than baked goods straight from the oven, and adding frosting and decorations makes it even more fun. Turn on music and dance while things bake.

    While parents or caregivers need to be involved with some of these activities (like the ones involving the oven, or reading out loud), kids can do many of them independently once you have it started. Which, really, is what children need: time to use their imagination and just play.

    But you just may find that once you have things started, you'll want to play, too.

  • Should you be tested for inflammation?

    Should you be tested for inflammation?

    A test tube with yellow top is filled with blood and has a blank label. It is lying sideways on top of other test tubes capped in different colors.

    Let’s face it: inflammation has a bad reputation. Much of it is well-deserved. After all, long-term inflammation contributes to chronic illnesses and deaths. If you just relied on headlines for health information, you might think that stamping out inflammation would eliminate cardiovascular disease, cancer, dementia, and perhaps aging itself.

    Unfortunately, that’s not true.

    Still, our understanding of how chronic inflammation can impair health has expanded dramatically in recent years. And with this understanding come three common questions: Could I have inflammation without knowing it? How can I find out if I do? Are there tests for inflammation? Indeed, there are.

    Testing for inflammation

    A number of well-established tests to detect inflammation are commonly used in medical care. But it’s important to note these tests can't distinguish between acute inflammation, which might develop with a cold, pneumonia, or an injury, and the more damaging chronic inflammation that may accompany diabetes, obesity, or an autoimmune disease, among other conditions. Understanding the difference between acute and chronic inflammation is important.

    These are four of the most common tests for inflammation:

    • Erythrocyte sedimentation rate (sed rate or ESR). This test measures how fast red blood cells settle to the bottom of a vertical tube of blood. When inflammation is present the red blood cells fall faster, as higher amounts of proteins in the blood make those cells clump together. While ranges vary by lab, a normal result is typically 20 mm/hr or less, while a value over 100 mm/hr is quite high.
    • C-reactive protein (CRP). This protein made in the liver tends to rise when inflammation is present. A normal value is less than 3 mg/L. A value over 3 mg/L is often used to identify an increased risk of cardiovascular disease, but bodywide inflammation can make CRP rise to 100 mg/L or more.
    • Ferritin. This is a blood protein that reflects the amount of iron stored in the body. It’s most often ordered to evaluate whether an anemic person is iron-deficient, in which case ferritin levels are low. Or, if there is too much iron in the body, ferritin levels may be high. But ferritin levels also rise when inflammation is present. Normal results vary by lab and tend to be a bit higher in men, but a typical normal range is 20 to 200 mcg/L.
    • Fibrinogen. While this protein is most commonly measured to evaluate the status of the blood clotting system, its levels tend to rise when inflammation is present. A normal fibrinogen level is 200 to 400 mg/dL.

    Are tests for inflammation useful?

    In certain situations, tests to measure inflammation can be quite helpful.

    • Diagnosing an inflammatory condition. One example of this is a rare condition called giant cell arteritis, in which the ESR is nearly always elevated. If symptoms such as new, severe headache and jaw pain suggest that a person may have this disease, an elevated ESR can increase the suspicion that the disease is present, while a normal ESR argues against this diagnosis.
    • Monitoring an inflammatory condition. When someone has rheumatoid arthritis, for example, ESR or CRP (or both tests) help determine how active the disease is and how well treatment is working.

    None of these tests is perfect. Sometimes false negative results occur when inflammation actually is present. False positive results may occur when abnormal test results suggest inflammation even when none is present.

    Should you be routinely tested for inflammation?

    Currently, tests of inflammation are not a part of routine medical care for all adults, and expert guidelines do not recommend them.

    CRP testing to assess cardiac risk is encouraged to help decide whether preventive treatment is appropriate for some people (such as those with a risk of a heart attack that is intermediate — that is, neither high nor low). However, for most people evidence suggests that routine CRP testing adds relatively little to assessment using standard risk factors, such as a history of hypertension, diabetes, smoking, high cholesterol, and positive family history of heart disease.

    So far, only one group I know of recommends routine testing for inflammation for all without a specific reason: companies selling inflammation tests directly to consumers.

    Inflammation may be silent — so why not test?

    It’s true that chronic inflammation may not cause specific symptoms. But looking for evidence of inflammation through a blood test without any sense of why it might be there is much less helpful than having routine health care that screens for common causes of silent inflammation, including

    • excess weight
    • diabetes
    • cardiovascular disease (including heart attacks and stroke)
    • hepatitis C and other chronic infections
    • autoimmune disease.

    Standard medical evaluation for most of these conditions does not require testing for inflammation. And your medical team can recommend the right treatments if you do have one of these conditions.

    The bottom line

    Testing for inflammation has its place in medical evaluation, and in monitoring certain health conditions such as rheumatoid arthritis. But it’s not clearly helpful as a routine test for everyone. A better approach is to adopt healthy habits and get routine medical care that can identify and treat the conditions that contribute to harmful inflammation.

  • Think your child has ADHD? What your pediatrician can do

    Think your child has ADHD? What your pediatrician can do

    A green blackboard with the letters A D H D in chalk, with hand-drawn, squiggly arrows in multiple colors of chalk pointing outward in all directions from the letters.

    ADHD, or attention deficit hyperactivity disorder, is the most common neurobehavioral disorder of childhood. It affects approximately 7% to 8% of all children and youth in the US. As the American Academy of Pediatrics (AAP) points out in their clinical practice guideline for ADHD, that’s more than the mental health system can handle, which means that pediatricians need to step up and help out.

    So, if your child is having problems with attention, focus, hyperactivity, impulsivity, or some combination of those, and is at least 4 years old, your first step should be an appointment with your child’s primary care doctor.

    What steps will your pediatrician take?

    According to the AAP, here’s what your doctor should do:

    Take a history. Your doctor should ask you lots of questions about what is going on. Be ready to give details and examples.

    Ask you to fill out a questionnaire about your child. Your doctor should also give you a questionnaire to give to your child’s teacher or guidance counselor.

    A diagnosis of ADHD is made only if a child has symptoms that are

    • present in more than one setting: For most children, that would be both home and school. If symptoms are only present in one setting, it’s less likely to be ADHD and more likely to be related to that setting. For example, a child who only has problems at school may have a learning disability.
    • causing a problem in both of those settings: If a child is active and/or easily distracted, but is getting good grades, isn’t causing problems in class, and has good relationships in school and at home, there is not a problem. It bears watching, but it could be just personality or temperament.

    There are ADHD rating scales that have been studied and shown to be reliable, such as the Vanderbilt and the Conners assessments. These scales can be very helpful, not just in making diagnoses, but also in following the progress of a child over time.

    Screen your child for other problems. There are problems that can mimic ADHD, such as learning disabilities, depression, or even hearing problems. Additionally, children who have ADHD can also have learning disabilities, depression, or substance use. It’s important to ask enough questions and get enough information to be sure.

    Discussing treatment options for ADHD

    If a diagnosis of ADHD is made, your pediatrician should discuss treatment options with you.

    • For 4- and 5-year-olds: The best place to begin is really with parent training on managing behavior, and getting support in the classroom. Medications should only be considered in this age group if those interventions don’t help, and the child’s symptoms are causing significant problems.
    • For 6- to 12-year-olds: Along with parent training and behavioral support, medications can be very helpful. Primary care providers can prescribe one of the FDA-approved medications for ADHD (stimulants, atomoxetine, guanfacine, or clonidine). In this age group, formal classroom support in the form of an Individualized Education Program (IEP) or a 504 plan should be in place.
    • For 12- to 18-year-olds: The same school programs and behavioral health support should be in place. Medications can be helpful, but teens should be part of that decision process; shared decision-making is an important part of caring for teens, and for getting them ready to take on their own care when they become adults.

    Follow-up care for a child with ADHD

    Your pediatrician also should follow up with you and your child. Early on, there should be frequent visits while you figure out the diagnosis, as well as any other possible problems. And if medication is prescribed, frequent visits are needed initially as you figure out the best medication and dose and monitor for side effects.

    After that, the frequency of the visits will depend on how things are going, but appointments should be regular and scheduled, not just made to respond to a problem. ADHD can be a lifelong problem, bringing different challenges at different times, and it’s important that you, your child, and your doctor meet regularly so that you can best meet those challenges.

    Because together, you can.

  • Are you getting health care you don’t need?

    Are you getting health care you don’t need?

    illustration in shades of green and white showing stylized medical objects: thermometer, bandage, medication bottle, stethoscope, syringe, clipboard, blister pack of pills

    Ever wonder if every medical test or treatment you've taken was truly necessary? Or are you inclined to get every bit of health care you can? Maybe you feel good about getting the most out of your health insurance. Perhaps a neighborhood imaging center is advertising discounted screening tests, your employer offers health screens as a perk, or you're intrigued by ads touting supplements for a seemingly endless number of conditions.

    But keep in mind: just because you could get a particular test or treatment or take a supplement doesn't mean you should. One study suggests that as much as 20% of all health care in the US is unneeded. In short: when it comes to health care, more is not always better.

    Isn't it better to be proactive about your health?

    We're all taught that knowledge is power. So it might seem reasonable to want to know as much as possible about how your body is working. And isn't it better to take action before there's a problem rather than waiting for one to develop? What's the harm of erring on the side of more rather than less?

    The truth is that knowledge is not always power: if the information is irrelevant to your specific situation, redundant, or inaccurate, the knowledge gained through unnecessary health care can be unhelpful or even harmful. Unnecessary tests, treatments, and supplements come with risks, even when they seem harmless. And, of course, unnecessary care is not free — even if you're not paying a cent out of pocket, it drives up costs across health systems.

    Screening tests, wellness strategies, and treatments to reconsider

    Recommended screening tests, treatments, and supplements can be essential to good health. But when risks of harm outweigh benefits — or if proof of any benefit is lacking — think twice. Save your time, money, and effort for health care that is focused on the most important health threats and backed by evidence.

    Cancer screening: When to stop?

    Screening tests for some cancers are routinely recommended and can be lifesaving. But there's a reason they come with a recommended stop age. For instance, guidelines recommend that a person at average risk of colorectal cancer with previously normal colonoscopies stop having them once they turn 75. Similar limits apply to Pap smears (age 65) and mammograms (age 75). Studies suggest that beyond those ages, there is little benefit to continuing these screens.

    Watch out for wellness marketing

    Dietary supplements are a multibillion-dollar industry. And a whopping 70% or more of US adults take at least one, such as vitamin D, fish oil, or a multivitamin. People often consider them as insurance in case vital elements are missing from their diet, or they believe supplements can prevent dementia, heart disease, or another condition.

    Yet little evidence supports a benefit of routine supplement use for everyone. While recent studies suggest a daily multivitamin might slow cognitive decline in older adults, there's no medical consensus that everyone should be taking a multivitamin. Fish oil (omega-3) supplements haven't proven to be as healthful as simply eating servings of fatty fish and other seafood low in toxic chemicals like mercury and PCBs. And the benefits of routinely taking vitamin D supplements remain unproven as well.

    It's worth emphasizing that dietary supplements clearly provide significant benefit for some people, and may be recommended by your doctor accordingly. For example, if you have a vitamin or mineral deficiency or a condition like age-related macular degeneration, good evidence supports taking specific supplements.

    Reconsider daily aspirin

    Who should be taking low-dose aspirin regularly? Recommendations have changed in recent years, so this is worth revisiting with your health care team.

    • Older recommendations favored daily low-dose aspirin to help prevent cardiovascular disease, including first instances of heart attack and stroke.
    • New recommendations favor low-dose aspirin for people who've already experienced a heart attack, stroke, or other cardiovascular disease. Adults ages 40 to 59 who are at a high risk for these conditions and low risk for bleeding also may consider it.

    Yet according to a recent study, nearly one-third of adults 60 and older without past cardiovascular disease take aspirin, despite evidence that it provides little benefit for those at average or low risk. Aspirin can cause stomach bleeding and raise risk for a certain type of stroke.

    Weigh in on prostate cancer screening

    Men hear about prostate cancer often. It's common, and the second leading cause of cancer deaths among men. But PSA blood tests and rectal exams to identify evidence of cancer in the prostate are no longer routinely recommended for men ages 55 to 69 by the United States Preventative Services Task Force.

    The reason? Studies suggest that performing these tests does not reliably reduce suffering or prolong life. Nor do possible benefits offset downsides like false positives (test results that are abnormal despite the absence of cancer). That can lead to additional testing, some of which is invasive.

    Current guidelines suggest making a shared decision with your doctor about whether to have PSA testing after reviewing the pros and cons. For men over age 70, no screening is recommended. Despite this, millions of men have PSA tests and rectal examinations routinely.

    Not everyone needs heart tests

    There are now more ways than ever to evaluate the health of your heart. But none are routinely recommended if you're at low risk and have no signs or symptoms of cardiovascular disease. That's right: in the absence of symptoms or a high risk of cardiovascular disease, it's generally safe to skip EKGs, stress tests, and other cardiac tests.

    Yet many people have these tests as part of their routine care. Why is this a problem? Having these tests without a compelling reason comes with risks, especially false positive results that can lead to invasive testing and unneeded treatment.

    Four more reasons to avoid unnecessary care

    Besides the concerns mentioned already, there are other reasons to avoid unnecessary care, including:

    • The discomfort or complications of testing. If you're needle-phobic, getting a blood test is a big deal. And while complications of noninvasive testing are rare (such as a skin infection from a blood test), they can occur.
    • The anxiety associated with waiting to find out test results
    • False reassurance that comes with false negatives (results that are normal or nearly so, suggesting no disease when disease is actually present)
    • All treatments have side effects. Even minor reactions — like occasional nausea or constipation — seem unacceptable if there's no reason to expect benefit from treatment.

    The bottom line

    You may believe your doctor wants you to continue with your current schedule of tests and treatments, while they might think this is your preference! It's worth discussing if you haven't already, especially if you suspect you may be taking pills or getting tests you don't truly need.

    If your doctor says you can safely skip certain tests, treatments, and supplements, it doesn't mean that he or she is neglecting your health or that you don't deserve great health care! It's likely that the balance of risks and benefits simply doesn't support doing these things.

    Less unnecessary care could free up resources for those who need it most. And it could save you time, money, and unnecessary risks or side effects, thus improving your health. It's a good example of how less can truly be more.

  • Shining light on night blindness

    Shining light on night blindness

    A dangerously blurry view of cars, streetlights, headlights through a car window at night; concept is night blindness

    Animals renowned for their outstanding night vision include owls, cats, tarsiers (a tiny primate in Southeast Asia) — and even the dung beetle.

    But humans? Not so much.

    Over time, many people suffer from night blindness, also known as nyctalopia. This condition makes seeing in dim or dark settings difficult because your eyes cannot adjust to changes in brightness or detect light.

    What are the dangers for those experiencing night blindness?

    Night blindness is especially problematic and dangerous when driving. Your eyes cannot adjust between darkness and the headlights of oncoming vehicles, other cars may appear out of focus, and your depth perception becomes impaired, which makes it difficult to judge distances.

    Night blindness also may affect your sight at home by making it hard for your vision to quickly adjust to a dark room after turning off the lights. “This can cause people to bump into furniture or trip and suffer an injury,” says Dr. Isabel Deakins, an optometrist with Harvard-affiliated Massachusetts Eye and Ear.

    What happens in the eye to create night blindness?

    The ability to see in low-light conditions involves two structures in the eye: the retina and the iris.

    The retina, located in the back of the eye, contains two types of light-detecting cells called cones and rods. The cones handle color vision and fine details while the rods manage vision in dim light.

    The iris is the colored part of your eye. It contains muscles that widen or narrow the opening of your pupil to adjust how much light can enter your eyes.

    If your irises don’t properly react, the pupils can dilate and let in too much light, which causes light sensitivity and makes it hard to see in bright light. Or your pupils may remain too small and not allow in enough light, making it tough to see in low light.

    What causes night blindness?

    Night blindness is not a disease but a symptom of other conditions. “It’s like having a bruise on your body. Something else causes it,” says Dr. Deakins.

    Several conditions can cause night blindness. For instance, medications, such as antidepressants, antihistamines, and antipsychotics, can affect pupil size and how much light enters the eye.

    Eye conditions that can cause night blindness include:

    • glaucoma, a disease that damages the eye’s optic nerves and blood vessels
    • cataracts, cloudy areas in the lens that distort or block the passage of light through the lens
    • dry eye syndrome.

    However, one issue that raises the risk of night blindness that you can’t control is age. “Our eyes react more slowly to light changes as we age, and vision naturally declines over time,” says Dr. Deakins.  “The number of rods in our eyes diminish, pupils get smaller, and the muscles of the irises weaken.”

    What helps if you have night blindness?

    If you notice any signs of night blindness, avoid driving and get checked by an eye care specialist like an optometrist or ophthalmologist. An eye exam can determine if your eyeglass prescription needs to be updated.

    “Often, a prescription change is enough to reduce glare when driving at night," says Dr. Deakins. “You may even need separate glasses with a stronger eye prescription that you wear only when driving at night.”

    Adding an anti-reflective coating to your lens may help to cut down on the glare of the headlights of an oncoming car. However, skip the over-the-counter polarized driving glasses sold at many drug stores. "These may help cut down on glare, but they don't address the causes of night blindness," says Dr. Deakins.

    An eye exam also will identify glaucoma or cataracts, which can be treated. Glaucoma treatments include eyedrops, laser treatment, or surgery. Cataracts are corrected with surgery to replace the clouded lens with an artificial one. Your eye care specialist can also help identify dry eye and recommend treatment.

    Ask your primary care clinician or a pharmacist if any medications that you take may cause night blindness. If so, it may be possible to adjust the dose or switch to another drug.

    Three more ways to make night driving safer

    You also can take steps to make night driving safer. For example:

    • Wash the lenses of your glasses regularly. And take them to an optician to buff out minor scratches.
    • Keep both sides of your front and rear car windshields clean so that you can see as clearly as possible.
    • Dim your dashboard lights, which cause glare, and use the night setting on your rearview mirror.
