You may already know that physical activity can boost your brain, strengthen your muscles and help you live longer. But it turns out that staying active also has powerful benefits that go beyond physical health.
Boosting your mood and helping you beat stress are two better known dividends paid by exercise. But the benefits go even further. A study of more than 18,000 middle-aged and older adults published in the Journal of Behavioral Medicine in April, for instance, showed a strong link between regular physical activity and feeling a greater sense of purpose in life.

"A sense of purpose comes from having goals and activities that add direction and meaning to life, and if you think about physical activity, that's exactly what it does,” said Ayse Yemiscigil, lead author of the study and a researcher with the Human Flourishing Program at Harvard University.
The study found that the association goes both ways. In other words, people who exercise more reported an increasing sense of purpose, while those whose sense of purpose was strong in the beginning were the most likely to exercise regularly.
"The more you get active, the more you get the sense of purpose — and vice versa,” Yemiscigil says. “It's an upward spiral.”
The findings are especially important for older adults because studies show that such a sense of purpose (and your activity level) tends to decline as you get older, Yemiscigil says. Maintaining this positive focus, on the other hand, has been tied to longevity and a lower risk of heart disease and Alzheimer's disease — not to mention that it's strongly linked to overall well-being.
Ilene Berns-Zare, a psychologist and professional coach, says having purpose is essential for finding that combination of physical, mental and emotional well-being that allows you to live your best life, a state that some call “flourishing.”
"It's very important to have a sense of purpose; it's one of the pillars for flourishing,” she says. “It's been shown to enhance your quality of life and your happiness.”
Yemiscigil's study is one of a growing number teasing out the psychological benefits of exercise. The benefits “almost seem to have no limit,” says Ramani Durvasula, a clinical psychologist based in Los Angeles. Exercise “makes us feel revitalized. It makes us feel stronger. It can even make us feel more powerful."
