Flowers, chocolates, organ donation — are you in?

Gifts of life are fitting on Valentine’s Day and any other day of the year.

February 8, 2024By Robert H. Shmerling, MD, Senior Faculty Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing

Chocolates and flowers are great gifts for Valentine’s Day. But what if the gifts we give then or throughout the year could be truly life-changing? A gift that could save a life or free someone from dialysis?

You can do this. For people in need of an organ, tissue, or blood donation, a donor can give them a gift that exceeds the value of anything that you can buy. Fittingly, Valentine’s Day is also known as National Donor Day, a time for blood drives and sign-ups for organ and tissue donation. Have you ever wondered what can be donated? Had reservations about donating after death or concerns about risks for live donors? Read on.

The enormous impact of organ, tissue, or cell donation

Imagine you have kidney failure requiring dialysis 12 or more hours each week just to stay alive. Even with this, you know you’re still likely to die a premature death. Or, if your liver is failing, you may experience severe nausea, itching, and confusion; death may only be a matter of weeks or months away. For those with cancer in need of a bone marrow transplant, or someone who’s lost their vision due to corneal disease, finding a donor may be their only good option.

Organ or tissue donation can turn these problems around, giving recipients a chance at a long life, a better quality of life, or both. And yet, the number of people who need organ donation far exceeds compatible donors. While national surveys have found about 90% of Americans support organ donation, only 40% have signed up. More than 103,000 women, men, and children are awaiting an organ transplant in the US. About 6,200 die each year, still waiting.

What can you donate?

The list of ways to help has grown dramatically. Some organs, tissues, or cells can be donated while you’re alive; other donations are only possible after death. A single donor can help more than 80 people!

After death, people can donate:

  • bone, cartilage, and tendons
  • corneas
  • face and hands (though uncommon, they are among the newest additions to this list)
  • kidneys
  • liver
  • lungs
  • heart and heart valves
  • stomach and intestine
  • nerves
  • pancreas
  • skin
  • arteries and veins.

Live donations may include:

  • birth tissue, such as the placenta, umbilical cord, and amniotic fluid, which can be used to help heal skin wounds or ulcers and prevent infection
  • blood cells, serum, or bone marrow
  • a kidney
  • part of a lung
  • part of the intestine, liver, or pancreas.

Which medicines are discontinued?

In January, GlaxoSmithKline stopped producing Flovent, which was available as a prescription metered-dose inhaler (Flovent HFA) and a dry powder inhaler (Flovent Diskus).

Both contain fluticasone, a steroid. Fluticasone reduces inflammation and swelling in the airways. Both types of inhalers are FDA-approved to help prevent asthma attacks.

However, children under age 5 and adults with particularly poor lung function may not be able to use a dry powder inhaler. They may lack the lung power necessary to breathe in deeply enough to pull the medicine into their airways, Dr. Feldman explains. A metered-dose inhaler could be the best choice for them.

Now that Flovent is discontinued, is a generic product available?

Yes, the drug manufacturer has licensed an authorized generic of both Flovent products: the metered-dose inhaler and the dry powder inhaler.

However, insurance coverage may not pay for the authorized generic because it may cost an insurer more than some other branded medicines. So, you may need to switch to another brand to stay healthy. Call your insurance company to check.

What are your alternatives?

This is a good chance for you and your doctor to review your asthma treatment plan. It may be a good time to make changes.

If you had been using Flovent daily for symptom control, your doctor may recommend:

  • Trying an inhaled steroid similar to Flovent. Many types of steroids will work, including beclomethasone (Qvar RediHaler), budesonide (Pulmicort Flexhaler), ciclesonide (Alvesco), and mometasone (Asmanex Twisthaler, Asmanex HFA). “These products use different molecules to do the same job as fluticasone,” says Dr. Feldman.
  • Switching to a combination inhaler. New studies suggest this approach may help many people who use Flovent daily for symptom control and only use a short-acting medicine to open airways when an asthma flare occurs (see here and here). If you have intermittent asthma symptoms, talk with your provider about whether you could use a combination inhaler when you start to wheeze or have shortness of breath. This combines a medicine called formoterol with a steroid. Symbicort provides this combination in one inhaler. Although not yet approved by the FDA for this specific use, it is approved in many other countries.

What else do asthma specialists advise people to do?

If your insurance covers the authorized generic, this may be a good choice because you already know how to use the product. But what if insurance won’t cover this?

Does drinking water before meals really help you lose weight?

Why people think it does and what the evidence says.

February 20, 2024By Robert H. Shmerling, MD, Senior Faculty Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing

If you’ve ever tried to lose excess weight, you’ve probably gotten this advice: drink more water. Or perhaps it was more specific: drink a full glass of water before each meal.

The second suggestion seems like a reasonable idea, right? If you fill your stomach with water before eating, you’ll feel fuller and stop eating sooner. But did that work for you? Would drinking more water throughout the day work? Why do people say drinking water can help with weight loss — and what does the evidence show?

Stretching nerves, burning calories, and thirst versus hunger

Three top theories are:

Feel full, eat less. As noted, filling up on water before meals has intuitive appeal. Your stomach has nerves that sense stretch and send signals to the brain that it’s time to stop eating. Presumably, drinking before a meal could send similar signals.

  • The evidence: Some small, short-term studies support this idea. For example, older study subjects who drank a full glass of water before meals tended to eat less than those who didn’t. Another study found that people following a low-calorie diet who drank extra water before meals had less appetite and more weight loss over 12 weeks than those on a similar diet without the extra water. But neither study assessed the impact of drinking extra water on long-term weight loss.

Burning off calories. The water we drink must be heated up to body temperature, a process requiring the body to expend energy. The energy spent on this — called thermogenesis — could offset calories from meals.

  • The evidence: Though older studies provided some support for this explanation, more recent studies found no evidence that drinking water burned off many calories. That calls the thermogenesis explanation for water-induced weight loss into question.

You’re not hungry, you’re thirsty. This explanation suggests that sometimes we head to the kitchen for something to eat when we’re actually thirsty rather than hungry. If that’s the case, drinking calorie-free water can save us from consuming unnecessary calories — and that could promote weight loss.

  • The evidence: The regulation of thirst and hunger is complex and varies over a person’s lifespan. For example, thirst may be dulled in older adults. But I could find no convincing studies in humans supporting the notion that people who are thirsty misinterpret the sensation for hunger, or that this is why drinking water might help with weight loss.

Exercise booster, no-cal substitution, and burning fat demands water

Being well-hydrated improves exercise capacity and thus weight loss. Muscle fatigue, cramping, and heat exhaustion can all be brought on by dehydration. That’s why extra hydration before exercise may be recommended, especially for elite athletes exercising in warm environments.

  • The evidence: For most people, hydrating before exercises seems unnecessary, and I could find no studies specifically examining the role of hydration to exercise-related weight loss.

Swapping out high calorie drinks with water. Yes, if you usually drink high-calorie beverages (such as sweetened sodas, fruit juice, or alcohol), consistently replacing them with water can aid weight loss over time.

  • The evidence: A dramatic reduction in calorie intake by substituting water for higher-calorie beverages could certainly lead to long-term weight loss. While it’s hard to design a study to prove this, indirect evidence suggests a link between substituting water for high-cal beverages and weight loss. Even so, just as calorie-restricting diets are hard to stick with over the long term, following a water-only plan may be easier said than done.

Burning fat requires water. Dehydration impairs the body’s ability to break down fat for fuel. So, perhaps drinking more water will encourage fat breakdown and, eventually, weight loss.

  • The evidence: Though some animal studies support the idea, I could find no compelling evidence from human studies that drinking extra water helps burn fat as a means to lose excess weight.

The bottom line

So, should you bump up hydration by drinking water before or during meals, or even at other times during the day?

Some evidence does suggest this might aid weight loss, at least for some people. But those studies are mostly small or short-term, or based on animal data. Even positive studies only found modest benefits.

Does sleeping with an eye mask improve learning and alertness?

If you’re seeking better cognitive health, start by turning off the lights at night.

February 21, 2024By Eric Zhou, PhD, Contributor

Red old-fashioned alarm clock next to black sleep mask against a turquoise and white background

All of us have an internal clock that regulates our circadian rhythms, including when we sleep and when we are awake. And light is the single most important factor that helps establish when we should feel wakeful (generally during the day) and when we should feel sleepy (typically at night).

So, let me ask you a personal question: just how dark is your bedroom? To find out why that matters — and whether sleeping in an eye mask is worthwhile — read on.

How is light related to sleep?

Our circadian system evolved well before the advent of artificial light. As anyone who has been to Times Square can confirm, just a few watts of power can trick the brain into believing that it is daytime at any time of night. So, what’s keeping your bedroom alight?

  • A tablet used in bed at night to watch a movie is more than 100 times brighter than being outside when there is a full moon.
  • Working on or watching a computer screen at night is about 10 times brighter than standing in a well-lit parking lot.

Light exposure at night affects the natural processes that help prepare the body for sleep. Specifically, your pineal gland produces melatonin in response to darkness. This hormone is integral for the circadian regulation of sleep.

What happens when we are exposed to light at night?

Being exposed to light at night suppresses melatonin production, changing our sleep patterns. Compared to sleeping without a night light, adults who slept next to a night light had shallower sleep and more frequent arousals. Even outdoor artificial light at night, such as street lamps, has been linked with getting less sleep.

But the impact of light at night is not limited to just sleep. It’s also associated with increased risk of developing depressive symptoms, obesity, diabetes, and high blood pressure. Light exposure misaligned with our circadian rhythms — that is, dark during the day and light at night — is one reason scientists believe that shift work puts people at higher risk for serious health problems.

Could sleeping with an eye mask help?

Researchers from Cardiff University in the United Kingdom conducted a series of experiments to see if wearing an eye mask while sleeping at night could improve certain measures of learning and alertness.

Roughly 90 healthy young adults, 18 to 35 years of age, alternated between sleeping while wearing an eye mask or being exposed to light at night. They recorded their sleep patterns in a sleep diary.

In the first part of the study, participants wore an intact eye mask for a week. Then during the next week, they wore an eye mask with a hole exposing each eye so that the mask didn’t block the light.

After sleeping with no light exposure (wearing the intact eye mask) and with minimal light exposure (the eye mask with the holes), participants completed three cognitive tasks on days six and seven of each week:

  • First was a paired-associate learning task. This helps show how effectively a person can learn new associations. Here the task was learning related word pairs. Participants performed better after wearing an intact eye mask during sleep in the days leading up to the test than after being exposed to light at night.
  • Second, the researchers administered a psychomotor vigilance test, which assesses alertness. Blocking light at night also improved reaction times on this task.
  • Finally, a motor skill learning test was given, which involved tapping a five-digit sequence in the correct order. For this task, there was no difference in performance whether participants had worn an intact eye mask or been exposed to light at night.

What else did the researchers learn?

No research study is ever perfect, so it is important to take the conclusions above with a grain of salt.

According to sleep diary data, there was no difference in the amount of sleep, nor in their perceptions of sleep quality, regardless of whether people wore an eye mask or not.

Further, in a second experiment with about 30 participants, the researchers tracked sleep objectively using a monitoring device called the Dreem headband. They found no changes to the structure of sleep — for example, how much time participants spent in REM sleep — when wearing an eye mask.

Should I rush out to buy an eye mask before an important meeting or exam?

If you decide to try using an eye mask, you probably don’t need to pay extra for overnight shipping. Instead, follow a chronobiologist’s rule of thumb: “bright days, dark nights.”

Which migraine symptoms are most common in children?

Migraines are often one-sided in adults. In children they are more likely to be felt on both sides of the head, either in both temples or both sides of the forehead.

While it’s not always easy to tell a migraine from another kind of headache, children

  • often report throbbing pain
  • may experience nausea and sensitivity to light and noise.

The flashing lights and other vision changes people often see as a migraine begins are less common in children. However, parents may notice that their child is more tired, irritable, or pale before a migraine begins — and takes a while to get back to normal after it ends.

What causes migraines in children?

We don’t know exactly what causes migraines. We used to think it had to do with blood flow to the brain, but that does not seem to be the case. It appears that migraines are caused by the nerves being more sensitive, and more reactive to stimulation. That stimulation could be stress, fatigue, hunger, almost anything.

Migraines run in families. In fact, most migraine sufferers have someone in the family who gets migraines too.

Can migraines be prevented?

The best way to prevent migraines is to identify and avoid triggers. The triggers are different in each person, which is why it’s a good idea to keep a headache diary.

When your child gets a headache, write down what was happening before the headache, how badly it hurt and where, what helped, and anything else about it you can think of. This helps you and your doctor see patterns that can help you understand your child’s particular triggers.

It’s a good idea to make sure your child gets enough sleep, eats regularly and healthfully, drinks water regularly, gets exercise, and manages stress. Doing this not only helps prevent migraines, but is also good for overall health!

How can you help your child ease a migraine?

When a migraine strikes, sometimes just lying down in a dark, quiet room with a cool cloth on the forehead is enough. If it’s not, ibuprofen or acetaminophen can be helpful; your doctor can tell you the best dose for your child.

It’s important not to give your child these medications more than about 14 days a month, as giving them more often can lead to rebound headaches and make everything worse!

Are there prescription medicines that can help children with migraines?

One more reason to brush your teeth?

Hospital-acquired pneumonia rates lower with twice-daily toothbrushing.

February 26, 2024By Maureen Salamon, Executive Editor, Harvard Women’s Health Watch

  • Reviewed by Howard E. LeWine, MD, Chief Medical Editor, Harvard Health Publishing

Maybe we should add toothbrushes to the bouquet of flowers we bring to friends and family members in the hospital — and make sure to pack one if we wind up there ourselves.

New Harvard-led research published online in JAMA Internal Medicine suggests seriously ill hospitalized patients are far less likely to develop hospital-acquired pneumonia if their teeth are brushed twice daily. They also need ventilators for less time, are able to leave the intensive care unit (ICU) more quickly, and are less likely to die in the ICU than patients without a similar toothbrushing regimen.

Why would toothbrushing make any difference?

“It makes sense that toothbrushing removes the bacteria that can lead to so many bad outcomes,” says Dr. Tien Jiang, an instructor in oral health policy and epidemiology at Harvard School of Dental Medicine, who wasn’t involved in the new research. “Plaque on teeth is so sticky that rinsing alone can’t effectively dislodge the bacteria. Only toothbrushing can.”

Pneumonia consistently falls among the leading infections patients develop while hospitalized. According to the Agency for Healthcare Research and Quality, each year more than 633,000 Americans who go to the hospital for other health issues wind up getting pneumonia. Air sacs (alveoli) in one or both lungs fill with fluid or pus, causing coughing, fever, chills, and trouble breathing. Nearly 8% of those who develop hospital-acquired pneumonia die from it.

How was the study done?

The researchers reviewed 15 randomized trials encompassing nearly 2,800 patients. All of the studies compared outcomes among seriously ill hospitalized patients who had daily toothbrushing to those who did not.

  • 14 of the studies were conducted in ICUs
  • 13 involved patients who needed to be on a ventilator
  • 11 used an antiseptic rinse called chlorhexidine gluconate for all patients: those who underwent toothbrushing and those who didn’t.

What were the findings?

The findings were compelling and should spur efforts to standardize twice-daily toothbrushing for all hospitalized patients, Dr. Jiang says.

Study participants who were randomly assigned to receive twice-daily toothbrushing were 33% less likely to develop hospital-acquired pneumonia. Those effects were magnified for people on ventilators, who needed this invasive breathing assistance for less time if their teeth were brushed.

Overall, study participants were 19% less likely to die in the ICU — and able to graduate from intensive care faster — with the twice-daily oral regimen.

How long patients stayed in the hospital or whether they were treated with antibiotics while there didn’t seem to influence pneumonia rates. Also, toothbrushing three or more times daily didn’t translate into additional benefits over brushing twice a day.

What were the study’s strengths and limitations?

One major strength was compiling years of smaller studies into one larger analysis — something particularly unusual in dentistry, Dr. Jiang says. “From a dental point of view, having 15 randomized controlled trials is huge. It’s very hard to amass that big of a population in dentistry at this high a level of evidence,” she says.

But toothbrushing techniques may have varied among hospitals participating in the research. And while the study was randomized, it couldn’t be blinded — a tactic that would reduce the chance of skewed results. Because there was no way to conceal toothbrushing regimens, clinicians involved in the study likely knew their efforts were being tracked, which may have changed their behavior.

“Perhaps they were more vigilant because of it,” Dr. Jiang says.

How exactly can toothbrushing prevent hospital-acquired pneumonia?

It’s not complicated. Pneumonia in hospitalized patients often stems from breathing germs into the mouth — germs which number more than 700 different species, including bacteria, fungi, viruses and other microbes.

This prospect looms larger for ventilated patients, since the breathing tube inserted into the throat can carry bacteria farther down the airway. “Ventilated patients lose the normal way of removing some of this bacteria,” Dr. Jiang says. “Without that ventilator, we can sweep it out of our upper airways.”

How much does toothbrushing matter if you’re not hospitalized?

In case you think the study findings only pertain to people in the hospital, think again. Rather, this drives home how vital it is for everyone to take care of their teeth and gums.

About 300 diseases and conditions are linked in some way to oral health. Poor oral health triggers some health problems and worsens others. People with gum disease and tooth loss, for example, have higher rates of heart attacks. And those with uncontrolled gum disease typically have more difficulty controlling blood sugar levels.

Is chronic fatigue syndrome all in your brain?

An NIH study expands on a body of research locating objective markers of ME/CFS in the brain, the immune system, the gut, and beyond.

February 28, 2024By Anthony L. Komaroff, MD, Editor in Chief, Harvard Health Letter

Chronic fatigue syndrome (CFS) –– or myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), to be specific ––  is an illness defined by a group of symptoms. Yet medical science always seeks objective measures that go beyond the symptoms people report.

A new study from the National Institutes of Health (NIH) has performed more diverse and extensive biological measurements of people experiencing CFS than any previous research. Using immune testing, brain scans, and other tools, the researchers looked for abnormalities that might drive health complaints like crushing fatigue and brain fog. Let’s dig into what they found and what it means.

What was already known about chronic fatigue syndrome?

In people with chronic fatigue syndrome, there are underlying abnormalities in many parts of the body: The brain. The immune system. The way the body generates energy. Blood vessels. Even in the microbiome, the bacteria that live in the gut. These abnormalities have been reported in thousands of published studies over the past 40 years.

Who participated in the NIH study?

Published in February in Nature Communications, this small NIH study compared people who developed chronic fatigue syndrome after having some kind of infection with a healthy control group.

Those with CFS had been perfectly healthy before coming down with what seemed like just a simple “flu”: sore throat, coughing, aching muscles, and poor energy. However, unlike their experiences with past flulike illnesses, they did not recover. For years, they were left with debilitating fatigue, difficulty thinking, a flare-up of symptoms after exerting themselves physically or mentally, and other symptoms. Some were so debilitated that they were bedridden or homebound.

All the participants spent a week at the NIH, located outside of Washington, DC. Each day they received different tests. The extensive testing is the great strength of this latest study.

What are three important findings from the study?

The study had three key findings, including one important new discovery.

First, as was true in many previous studies, the NIH team found evidence of chronic activation of the immune system. It seemed as if the immune system was engaged in a long war against a foreign microbe — a war it could not completely win and therefore had to keep fighting.

Second, the study found that a part of the brain known to be important in perceiving fatigue and encouraging effort — the right temporal-parietal area — was not functioning normally. Normally, when healthy people are asked to exert themselves physically or mentally, that area of the brain lights up during an MRI. However, in the people with CFS it lit up only dimly when they were asked to exert themselves.

While earlier research had identified many other brain abnormalities, this one was new. And this particular change makes it more difficult for people with CFS to exert themselves physically or mentally, the team concluded. It makes any effort like trying to swim against a current.

Third, in the spinal fluid, levels of various brain chemicals called neurotransmitters and markers of inflammation differed in people with CFS compared with the healthy comparison group. The spinal fluid surrounds the brain and reflects the chemistry of the brain.

What else did study show?

There are some other interesting findings in this study. The team found significant differences in many biological measurements between men and women with chronic fatigue syndrome. This surely will lead to larger studies to verify these gender-based differences, and to determine what causes them.

There was no difference between people with CFS and the healthy comparison group in the frequency of psychiatric disorders — currently, or in the past. That is, the symptoms of the illness could not be attributed to psychological causes.

Is chronic fatigue syndrome all in the brain?

The NIH team concluded that chronic fatigue syndrome is primarily a disorder of the brain, perhaps brought on by chronic immune activation and changes in the gut microbiome. This is consistent with the results of many previous studies.

The growing recognition of abnormalities involving the brain, chronic activation (and exhaustion) of the immune system, and of alterations in the gut microbiome are transforming our conception of CFS –– at least when caused by a virus. And this could help inform potential treatments.

For example, the NIH team found that some immune system cells are exhausted by their chronic state of activation. Exhausted cells don’t do as good a job at eliminating infections. The NIH team suggests that a class of drugs called immune checkpoint inhibitors may help strengthen the exhausted cells.

What are the limitations of the study?

The number of people who were studied was small: 17 people with ME/CFS and 21 healthy people of the same age and sex, who served as a comparison group. Unfortunately, the study had to be stopped before it had enrolled more people, due to the COVID-19 pandemic.

That means that the study did not have a great deal of statistical power and could have failed to detect some abnormalities. That is the weakness of the study.

4 things everyone needs to know about measles

Measles outbreaks have become more common, and are especially dangerous for younger children and people who are pregnant or immunocompromised.

September 14, 2023By Claire McCarthy, MD, Senior Faculty Editor, Harvard Health Publishing

When measles broke out in 31 states several years ago, health experts were surprised to see more than 1,200 confirmed cases –– the largest number reported in the US since 1992.

Measles is a very contagious, preventable illness that may cause serious health complications, especially in younger children and people who are pregnant, or whose immune systems aren’t working well. While a highly effective vaccine is available, vaccination rates are low in some communities across the US. This sets the stage for large outbreaks.

Here are four things that everyone needs to know about measles.

Measles is highly contagious

This is a point that can’t be stressed enough. A full 90% of unvaccinated people exposed to the virus will catch it. And if you think that just staying away from sick people will do the trick, think again. Not only are people with measles infectious for four days before they break out with the rash, but the virus can live in the air for up to two hours after an infectious person coughs or sneezes. Just imagine: if an infectious person sneezes in an elevator, everyone riding that elevator for the next two hours could be exposed.

It’s hard to know that a person has measles when they first get sick

The first symptoms of measles are a high fever, cough, runny nose, and red, watery eyes (conjunctivitis), which could be confused with any number of other viruses, especially during cold and flu season. After two or three days people develop spots in the mouth called Koplik spots, but we don’t always go looking in our family members’ mouths. The characteristic rash develops three to five days after the symptoms begin, as flat red spots that start on the face at the hairline and spread downward all over the body. At that point you might realize that it isn’t a garden-variety virus — and at that point, the person would have been spreading germs for four days.

Measles can be dangerous

Most of the time, as with other childhood viruses, people weather it fine, but there can be complications. Children less than 5 years old and adults older than 20 are at highest risk of complications. Common and milder complications include diarrhea and ear infections (although the ear infections can lead to hearing loss), and one out of five will need to be hospitalized, but there also can be serious complications:

  • One in 20 people with measles gets pneumonia. This is the most common cause of death from the illness.
  • One in 1,000 gets encephalitis, an inflammation of the brain that can lead to seizures, deafness, or even brain damage.
  • One to three in 1,000 children who get it will die.

Another possible complication can occur seven to 10 years after infection, more commonly when people get the infection as infants. It’s called subacute sclerosing panencephalitis, or SSPE. While it is rare (four to 11 out of 100,000 infections), it is fatal.

We’re all supposed to strengthen our muscles at least twice a week and get a total at least 150 minutes of weekly aerobic activity (the kind that gets your heart and lungs working). But fewer than 18% of U.S. adults meet those weekly recommendations, according to the CDC.

How can choosing to become more active help? A brighter mood is one benefit: physical activity helps ease depression and anxiety, for example. And being sufficiently active — whether in short or longer chunks of time — also lowers your risk for health problems like

  • heart disease
  • stroke
  • diabetes
  • cancer
  • brain shrinkage
  • muscle loss
  • weight gain
  • poor posture
  • poor balance
  • back pain
  • and even premature death.

What are your exercise obstacles?

Even when we understand these benefits, a range of obstacles may keep us on the couch.

Don’t like the cold? Have trouble standing, walking, or moving around easily? Just don’t like exercise? Don’t let obstacles like these stop you anymore. Try some workarounds.

  • If it’s cold outside: It’s generally safe to exercise when the mercury is above 32° F and the ground is dry. The right gear for cold doesn’t need to be fancy. A warm jacket, a hat, gloves, heavy socks, and nonslip shoes are a great start. Layers of athletic clothing that wick away moisture while keeping you warm can help, too. Consider going for a brisk walk or hike, taking part in an orienteering event, or working out with battle ropes ($25 and up) that you attach to a tree.
  • If you have mobility issues: Most workouts can be modified. For example, it might be easier to do an aerobics or weights workout in a pool, where buoyancy makes it easier to move and there’s little fear of falling. Or try a seated workout at home, such as chair yoga, tai chi, Pilates, or strength training. You’ll find an endless array of free seated workout videos on YouTube, but look for those created by a reliable source such as Silver Sneakers, or a physical therapist, certified personal trainer, or certified exercise instructor. Another option is an adaptive sports program in your community, such as adaptive basketball.

Ever worry about your gambling?

A simple gambling screening test can point people toward help.

Are online gambling and sports betting new to your area? Are gambling advertisements catching your eye? Have you noticed sports and news shows covering the spread? Recent changes in laws have made gambling widely accessible, and its popularity has soared.

Occasional bets are rarely an issue. But uncontrolled gambling can lead to financial, psychological, physical, and social consequences, some of which are extreme. Understanding whether gambling is becoming a problem in your life can help you head off the worst of these issues and refocus on having more meaning, happiness, and psychological richness in your life. Gambling screening is a good first step.

  • During the past 12 months, have you become restless, irritable, or anxious when trying to stop/cut down on gambling?
  • During the past 12 months, have you tried to keep your family or friends from knowing how much you gambled?
  • During the past 12 months, did you have such financial trouble as a result of your gambling that you had to get help with living expenses from family, friends, or welfare?

What do your answers mean?

Answering yes to any one of these questions suggests that you are at higher risk for experiencing gambling disorder. Put simply, this is an addiction to gambling. Like other expressions of addiction, for gambling this includes loss of control, craving, and continuing despite bad consequences. Unique to gambling, it also often means chasing your losses.

A yes doesn’t mean that you are definitely experiencing a problem with gambling. But it might be valuable for you to seek a more in-depth assessment of your gambling behavior. To find an organization or person qualified to help, ask a health care provider, your local department of public health, or an advocacy group like the National Council on Problem Gambling.

Are you ready for change?

Your readiness to change a behavior matters when deciding the best first steps for making a change. If someone asks you whether you want to change your gambling, what would you say?

I never think about my gambling.Sometimes I think about gambling less.I have decided to gamble less.I am already trying to cut back on my gambling.I changed my gambling: I now do not gamble, or gamble less than before.

Depending on your answer, you might seek out different solutions. What’s most important initially is choosing a solution that feels like the right fit for you.

What if you don’t feel ready to change? If you haven’t thought about your gambling or only occasionally think about changing your gambling, you might explore lower intensity actions. For example, you could

  • read more about how gambling could create a problem for you
  • listen to stories of those who have lived experience with gambling disorder.

If you are committed to making a change or are already trying to change, you might seek out more engaging resources and strategies to support those decisions, like attending self-help groups or participating in treatment.

Read on for more details on choices you might make.

What options for change are available if you want to continue gambling?

If you want to keep gambling in some way, you might want to stick to lower-risk gambling guidelines:

  • gamble no more than 1% of household income
  • gamble no more than four days per month
  • avoid regularly gambling at more than two types of games, such as playing the lottery and betting on sports.

Other ways to reduce your risk of gambling harm include:

  • Plan ahead and set your own personal limits.
  • Keep your entertainment budget in mind if you decide to gamble.
  • Consider leaving credit cards and debit cards at home and use cash instead.
  • Schedule other activities directly after your gambling to create a time limit.
  • Limit your use of alcohol and other drugs if you decide to gamble.

What are easy first steps toward reducing or stopping gambling?

If you’re just starting to think about change, consider learning more about gambling, problem gambling, and ways to change from

  • blogs, like The BASIS
  • books like Change Your Gambling, Change Your Life
  • podcasts like After Gambling, All-In, and Fall In, which offer expert interviews, personal recovery stories, and more.

Some YouTube clips demystify gambling, such as how slot machines work, the limits of skill and knowledge in gambling, and how gambling can become an addiction. These sources might help you think about your own gambling in new ways, potentially identifying behaviors that you need to change.
