What's the secret to living longer? A Harvard study published online April 30, 2018, by Circulation suggests that it may come down to five healthy habits: eating a healthy diet, exercising daily, keeping a healthy body weight, drinking alcohol only in moderation, and not smoking. Researchers combed through information from two large studies that tracked more than 123,000 men and women for about three decades. Scientists estimated that life expectancy for study participants (at age 50) was 79 for women and 75 for men, if they didn't maintain healthy habits. But if they adopted all five habits, life expectancy at age 50 jumped to 93 for women and 87 for men. And following even one healthy habit was associated with a lower risk for dying young. The study is only observational and doesn't prove that healthy habits extend your life. But the findings build on similar research. "It's never too late to make positive lifestyle changes. Even for those who are 70 or older, following a healthy lifestyle such as eating a healthy diet and being physically active can add more years to life," says Dr. Frank Hu, senior author of the study and chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health.

Exercising regularly throughout life is the best way to keep your heart healthy. But starting to exercise even in late middle age may lessen the risk of heart failure, according to a report in the May 15 issue of Circulation. Heart failure, a gradual decline in the heart's ability to pump enough blood to meet the body's needs, affects about 6.5 million people in the United States.

The study involved more than 11,000 people who were part of a long-running project begun in the late 1980s, the Atherosclerosis Risk in Communities Study. Every six years, participants got medical testing and filled out questionnaires about their physical activity.

Aerobic exercise has been linked with reducing symptoms of depression, but resistance training, such as weight lifting and bodyweight exercises like push-ups, can have the same effect.

A meta-analysis published in the June 2018 JAMA Psychiatry examined the effects of resistance training on depression symptoms in 33 clinical trials involving 1,877 people. The researchers found that people who did this type of exercise reported a significant reduction in such symptoms as low mood, loss of interest in activities, and feelings of worthlessness, compared with those who did not exercise.

There's an old saying: "If you want to stay moving, you have to get moving." But for a lot of us, that's easier said than done.
