Rapidly becoming a racquet sport favorite, pickleball serves up various physical, mental, and social benefits.

You keep hearing that older adults need to stay active physically, mentally, and socially. But what if you could do all three at once? You can if you play the racquet sport pickleball, one of the country's fastest-growing forms of recreation.

"In many ways, pickleball is the ideal activity for older adults," says Timothy Rivotto, a physical therapist and tennis coach with Harvard-affiliated Spaulding Rehabilitation Network. "It can accommodate people with different fitness levels and still offer a good aerobic workout. Pickleball also requires using key brain skills and is an exciting way to interact with others."

Living a healthy lifestyle may be one of the best things you can do to tame the heartburn of gastroesophageal reflux disease (GERD), suggests a research letter published online Jan. 4, 2021, by JAMA Internal Medicine. Harvard researchers analyzed the self-reported health information of about 43,000 middle-aged women who were followed for 10 years. Women who adhered to five healthy lifestyle factors, regardless of whether they took heartburn medication, appeared to prevent nearly 40% of their GERD symptoms each week. The pill-free approaches included maintaining a healthy body weight (a body mass index between 18.5 and 24.9); not smoking; getting 30 minutes daily of moderate-to-vigorous physical activity; limiting coffee, tea, or soda to no more than 2 cups per day; and eating a healthy diet. "Each one of these factors may prevent the inappropriate relaxation of the sphincter muscle between the stomach and the esophagus, helping to keep acid from refluxing up and causing heartburn. For example, carrying extra weight around the waist can push on the stomach, forcing stomach acid up into the esophagus," says Dr. Raaj S. Mehta, lead author of the study and a gastroenterology fellow at Harvard-affiliated Massachusetts General Hospital.

Strengthening your core will rev up your balance and stability.

After a long winter with lots of isolating and maybe too little physical activity, it might be time to give your core muscles more attention.

These muscles, located throughout much of your trunk, are the key to supporting your lower back and helping you stand, get out of a chair, bend, lift, and maintain your balance. So regular maintenance and tune-ups of the core muscles are important.

Lifestyle changes may help to prevent symptoms related to gastroesophageal reflux disease (GERD), according to a research letter published online Jan. 4, 2021, by JAMA Internal Medicine.

Using data from the Nurses' Health Study II, a nationwide study that included 116,671 women, researchers found that among 9,000 women who had GERD symptoms, those who met five specific anti-reflux lifestyle criteria were 40% less likely to have GERD symptoms than women who did not meet any of them. These were having a normal body weight; never smoking; participating in 30 minutes of moderate or vigorous exercise each day; drinking no more than two cups of coffee, tea, or soda each day; and following a healthy diet. GERD symptoms were defined as reporting acid reflux or heartburn at least once a week.

Surveys show that about one in five Americans uses a smartphone app or tracker for monitoring exercise. Evidence for the benefits of these tools is mixed, but a new review suggests they may encourage people to move a bit more.

Researchers pooled findings from 28 studies involving a total of nearly 7,500 people who took part in studies using a smartphone app or activity tracker. They found that these tools have a small to moderate effect in boosting physical activity, motivating people to take an average of 1,850 additional steps per day.

A good one can provide motivation and customized advice on a safe, effective, and well-rounded exercise routine.

Exercise is one of the pillars of heart disease prevention. But at some point, you may need help shoring up your workout habits. Maybe you exercise only in fits and starts, without sticking to a regular routine. Or perhaps you're in a rut, doing the same old 30-minute trudge on the treadmill every day.

Another possibility: You have a health condition (such as high blood pressure or arthritis) or another physical problem (an old knee or back injury, for example) that makes you hesitant to exercise. For all of these reasons and more, hiring a personal trainer can be a sound investment.
