Q. I read that the death rate from COVID-19 is going down, but that people who recover from the infection still can remain sick for a long time. Is that true?

A. It is true, but we don't yet know how big the problem is: COVID-19 has been with us for only a year, and there hasn't been enough time to know the long-term effects.

Even if you're isolating to avoid COVID-19, it's still important to be proactive when it comes to allergies.

This is normally the time of year to think about taking medications to ward off spring allergies. Starting treatment about a month before the season (which begins in February in some parts of the country) gives the drug time to achieve its full effect and prevent symptoms.

But the pandemic may have you questioning that approach: is an early regimen necessary if you're isolating and you're not going outside very often? The answer is yes. "Even a short walk around the neighborhood, sitting on a patio, or simply opening the windows for fresh air could expose you to allergens," says Dr. Anna Wolfson, an allergist and immunologist at Harvard-affiliated Massachusetts General Hospital.

Make this year's batch of New Year's resolutions stick by taking a new approach.

It's a new year, and you've got a resolution in mind. Whether it's aiming for a healthier diet, improving your stress management, or finally committing to that daily workout, achieving your goal probably won't be easy. Resolutions made on New Year's Day are often in the trash bin by Valentine's Day. But this year can be different if you learn how to COACH yourself to success.

Dr. Beth Frates, an assistant professor of physical medicine and rehabilitation at Harvard Medical School, designed a strategy she calls COACH to move you toward your goals. It's a process that can help sidestep pitfalls that may have derailed you in the past.

Q. I have mild cataracts. Is it important for me to get surgery now to correct the problem?

A. Not necessarily. Cataracts, a condition marked by clouding of the eye's lens, are not a threat to your health. If they're not bothering you or affecting your vision during important tasks, such as driving, you don't need to get surgery if you don't want to. Typically, the vision changes associated with cataracts slowly worsen over time. These may include problems such as cloudy, blurred, or dim vision; sensitivity to the glare from lights; faded colors; or seeing halos around lights. Initially, cataracts might not affect your life too much. You can often successfully manage the vision problems they cause by getting new glasses or contact lenses.

Make sure it's tailored to your needs and has the elements that are essential for health and safety.

You've resolved to exercise more, and you're looking for an online exercise video that will help you achieve your fitness goals. That's a great start, but there's more to choosing an exercise video than simply finding workouts that appeal to you. "Online exercise videos aren't regulated. And trying to keep up with a workout that isn't designed for older adults could lead to injury," says Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School and Whole Health medical director at VA Boston Healthcare System.

Where to start

YouTube is a rich resource for effective exercise videos. You can find workouts designed for older adults from hospitals, government health agencies, academic centers (including Harvard Medical School), personal trainers, and senior centers. However, YouTube also contains scores of workout videos that could be risky for older adults. So it takes work to find a workout tailored to your needs.

While playing video games can be a fun pastime, and there are some potential benefits, there are health risks associated with too much gaming. They include repetitive stress injuries, vision problems, sleep deprivation, depression, and possibly addiction to playing.

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.

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.
