More proof that exercise is good for the body and the brain.

Yale researchers found active people have one and a half fewer days of poor mental health a month than their sedentary peers. An hour a day, of team sports, cycling, aerobics or going to a gym was best for reducing depression.

But extreme exercise had the opposite effect. People who worked out more than three hours a day had worse mental health than those who did not exercise at all.

Impact of exercise on certain cancers

A separate study shows many Americans are unaware that a lack of exercise may increase the risk of some cancers.

Researchers at the University Of Washington in St. Louis surveyed over 1,000 adults. While most knew insufficient exercise caused weight and heart problems, only 3 percent knew it boosted the risk of breast and colon cancer.
