Researchers measuring activity levels found that people who tend to go to bed later and sleep later also tend to get less physical activity, compared to early risers. However, these results don't mean that being a night owl is the cause of getting less activity, or that such behavior can't be changed.

A few adjustments may be all it takes to help you keep your mask on and your COVID guard up.

We all have to wear face masks these days to help reduce the spread of COVID-19. But wearing a mask can be uncomfortable. The fix may just be a matter of trying a different type of mask (see "What to look for in a cloth mask").

Here are some common mask complaints and ways to resolve them.

The benefits of tub baths are more than skin deep. Bathing regularly can help ease pain and potentially benefit your heart.

You know that sinking into a warm bath at the end of a long day can help you relax and unwind, but did you know it might also be good for your health? Research shows that using baths as a form of medical therapy, sometimes referred to as balneotherapy (see "Balneotherapy, or bath therapy"), can bring health benefits — among them, easing certain types of chronic pain, helping your skin, and potentially even improving heart health.

Ask the doctor

Q. How many hours of sleep do I need each night, and how do I improve the quality of my sleep?

A. Adults need to average between seven and nine hours of sleep per night. If you're over 65, eight hours might be enough. The occasional short night of sleep won't hurt you.

Certain drugs or treatments may affect the skin, causing side effects like excessive dryness or blue spots.

Having problems with your skin? You may want to look in your medicine cabinet. Numerous prescription drugs and even over-the-counter treatments may bring unexpected skin changes, says Dr. Suzanne Olbricht, an associate professor of dermatology at Harvard Medical School. Medications to look out for include the following.

Blood-thinning medications

Spontaneous bruising that occurs even without bumping into something becomes more common as you get older. Doctors call it senile or actinic purpura and it happens often in people who take medication to prevent blood clots, such as warfarin (Coumadin) or even a baby aspirin. "As you age, the dermis, the thick middle layer of the skin, begins to thin and doesn't support the blood vessels inside as well as it used to," says Dr. Olbricht. This can make the blood vessels more likely to break. Even the tiniest injury can release blood under the skin, leading to the discoloration and dark purple bruises that characterize this condition.

Research we're watching

American adults are gaining weight, according to data from the CDC. Twelve U.S. states now have obesity rates of 35% or higher, compared with just six states in 2017 and nine states in 2018. Experts say the trend is particularly concerning because adults with obesity are more prone to severe outcomes from COVID-19.

According to the CDC report, racial and ethnic minority groups are disproportionately affected by obesity. Prevalence rates nationwide were

Early stages of vision-robbing diseases often have no symptoms.

Once you reach age 65, you need comprehensive, dilated eye exams every one or two years — more often if you have eye problems. But doctors say the pandemic is keeping some people from getting eye care.

"Some people are delaying treatment, trying to avoid crowds or health facilities like hospitals. They're not getting their eye pressure checked, and they're not using their eye medications," says Dr. Roberto Pineda, an ophthalmologist and eye surgeon at Harvard-affiliated Massachusetts Eye and Ear.

Try over-the-counter medications, water flossers, and rinses.

Gum pain is hard to ignore. The aching, stinging sensation can linger for days and make eating uncomfortable. If the pain is new, you may worry it signals an undiagnosed condition. As you search for answers, you can relieve pain with a number of home remedies and over-the-counter options.

Sore gum causes

Sore gums have many potential causes. One of the most common is an early (often reversible) stage of gum disease called gingivitis. It happens when buildup of plaque (a sticky film containing bacteria) irritates the gums, making them red, swollen, and prone to bleeding easily.

Bisphenol A (BPA), used to make some plastics and epoxy resins, has made headlines for years because of its association with an increased risk for obesity, diabetes, high blood pressure, and cardiovascular disease in humans. Now high levels of BPA exposure have been linked to an increased risk for premature death from any cause, according to a study published online Aug. 17, 2020, by JAMA Network Open. Scientists analyzed the survival rates of about 3,900 people who provided health information and urine samples and were then followed for 10 years. People with the highest levels of BPA in their urine had a 51% higher risk of dying during that period, primarily from heart disease, compared with people who had the lowest levels of BPA. The findings don't prove that BPA caused premature death, but they add to concerns about BPA's potential toxicity. BPA and related chemicals are found in many products, such as water bottles, cups, dental sealants, paper receipts, and the linings of food and beverage cans and pipes, so it's hard to avoid them. Simple precautions include relying less on canned foods and more on fresh foods; avoiding plastics with a 3 or 7 recycling label; microwaving food in glass or ceramic containers, not plastic; and looking for BPA-free products.

The COVID-19 pandemic has prompted a surge in telemedicine visits. Here's what you need to know about virtual health care.

Telemedicine — interactions with your doctor by video — has been slowly growing for years. But when the COVID-19 pandemic hit the United States earlier this year and forced people into isolation, this emerging form of virtual health care took off.

"In 2020, we've seen a sharp hockey stick–like movement in the number of telemedicine visits," says Dr. Joseph Kvedar, a dermatologist with Harvard-affiliated Massachusetts General Hospital and president of the American Telemedicine Association. "The experience has shown both patients and doctors the many ways telemedicine can improve health care in the current environment and beyond. It appears to be here to stay."
