You can ease the pain of sitting too much by getting up and moving around. Try these stretches and exercises.

An excess of inactivity isn't just bad for overall health; it can literally be a pain in the butt. You could end up with a sore backside if you sit at a desk all day long, if you're confined to a wheelchair, if you sit on hard surfaces for long periods, or if you're simply not as active as you once were. Whatever the reason for rear-end pain, it's time to stand up and get a little relief.

What's causing your pain?

When you sit in a chair, you're resting on your ischial tuberosities, or "sit bones" — the bony prominences at the bottom of your pelvis. You're also placing lots of pressure on your lower back, nerves, muscles, tendons, and ischial bursae (fluid-filled sacs near the ischial bones). Sitting can aggravate (or in some cases cause) these common sources of buttocks pain.

People with chronic pain may be more likely to have a heart attack or stroke than those without chronic pain, according to a study published online May 7, 2020, by the journal Pain Medicine.

From 2001 to 2005, researchers identified 17,614 Taiwanese people who had used pain relievers for at least three months. The most common causes of pain were spinal disorders, arthritis, and headaches; the pain relievers included both over-the-counter drugs and prescription opioids. For the comparison group, researchers used 35,228 people without chronic pain who were matched by age and sex to those in the first group.

Even in an unusual year, tried-and-true strategies are still the best way to prevent illness.

Staying healthy is likely at the top of your list almost every winter. But this year, in the midst of a pandemic, it may be even more of a concern than usual. You might wonder: should you be taking special supplements to boost your immune system, or investing in cleaning devices to zap germs?

While the viral threats may be different from usual this year, the truth is that you should still be using many of the same strategies that you use in a typical year, says Michael Starnbach, a professor of microbiology at Harvard Medical School. Below are five of his top tips that can help you keep yourself and your loved ones safe.

From badminton to pickleball to tennis, hitting objects across a net can be a fun, effective way to get in shape.

Looking for an exercise that gets your heart pumping and strengthens muscles in your legs, arms, and core? Tennis and other racquet sports can serve up all those benefits and more. In fact, several long-running studies have linked racquet sports to a lower risk of cardiovascular disease and a longer life.

"Playing tennis is an amazing workout. And no matter how good you are, you can have fun doing it," says Joe DiVincenzo, a physical therapist at Harvard-affiliated Spaulding Rehabilitation Hospital and former competitive tennis player. In general, racquet sports engage muscles throughout your upper and lower body, which challenges your heart. During a match, you do frequent, short bursts of high-intensity activity interspersed with less vigorous movements — a perfect example of interval training. Also known as HIIT (high-intensity interval training), this workout strategy seems to be a good way to boost cardiovascular fitness.

It's well established that regular exercise is healthy. But how much exercise do you need to achieve health benefits? Even just a little activity — both at home and at work — may reduce your risk of hospitalization, suggests a long-term observational study published May 6, 2020, in BMC Geriatrics. Researchers analyzed the self-reported workplace and leisure activity of 25,000 men and women ages 40 to 79 over a 20-year period. During the first 10 years of the study, people who were active were 25% less likely to be hospitalized for more than 20 days per year, compared with people who were inactive. In the second 10 years of the study, people who remained active or became active — even just slightly — were 34% less likely to be hospitalized for more than 20 days per year. Also, people who were inactive or became inactive during the study had the highest risk of being hospitalized. The take-home message: Stay as active as you can, whether it's a brisk walk most days of the week or just vigorous housework. Even a little activity protects your health.

Regular, moderate-to-vigorous exercise may help prevent atrial fibrillation (afib), according to a study in the May 2020 issue of The American Journal of Cardiology.

Previous studies looking at the connection between afib (which causes a rapid, irregular heart rate) and exercise have produced conflicting results. But those studies relied on participants to self-report their exercise habits. For the new study, the 5,147 participants wore devices that measured their activity levels for four to seven consecutive days.

Active-play video games may encourage adults — including those with heart disease — to be more active.

Looking to liven up your indoor exercise routine? You might want to try exergaming — a fitness trend that incorporates exercise into a video game. Also called gamercising, the workouts may be more motivating and fun than a traditional exercise video.

"One advantage to exergaming is that the game choices are so broad, you can tailor the exercise to your own particular interest," says Dr. Ashwin Babu, a sports medicine physiatrist at Harvard-affiliated Massachusetts General Hospital. Depending on the video gaming system, you can choose from a wide array of simulated sports and recreational activities, including baseball, bowling, boxing, cycling, football, golf, table tennis, track and field events, skateboarding, skiing, tennis, and volleyball. Some offer muscle-strengthening workouts, balance and stretching, aerobic exercises, dancing, and martial arts. Others feature adventure games that you "play" with your body movements, such as moving your arms, jumping, squatting, running in place, and sidestepping.

Slower gait speed and cognitive decline may be related, according to a study published online April 12, 2020, by the International Journal of Geriatric Psychiatry.

Scientists recorded the gait speed and cognitive health of 370 people in the San Antonio Longitudinal Study of Aging (SALSA). Cognitive health was measured with a test that assessed orientation to time and place, attention, recall, language, and other aspects. Gait speed was measured with a timed 10-foot walk.
