PHILADELPHIA (KYW Newsradio) — Regular exercise can reduce the incidence of heart disease and dramatically cut down the risk of developing diabetes. Combined with a healthy diet, these lifestyle changes can make a big difference.
But there are other key advantages of exercise.
A review of nine studies involving more than 750,000 adults has found that regular exercise is linked to a lower risk for seven cancers, with several cancer types having a "dose/response" relationship.
The study was led by investigators at the National Cancer Institute, the American Cancer Society, and the Harvard School of Public Health.
People should aim for 2.5 to 5 hours per week of moderate intensity activity, or 1.25 to 2.5 hours per week of vigorous activity.
