Adults 18 and older need 30 minutes of physical activity on five or more days a week to be healthy; children and teens need 60 minutes of activity a day for their health.
Significant health benefits can be obtained by including a moderate amount of physical activity (e.g., 30 minutes of brisk walking or raking leaves, 15 minutes of running, 45 minutes of playing volleyball). Additional health benefits can be gained through greater amounts of physical activity.
Thirty to sixty minutes of activity broken into smaller segments of 10 or 15 minutes throughout the day has significant health benefits.
Moderate daily physical activity can reduce substantially the risk of developing or dying from cardiovascular disease, type 2 diabetes, and certain cancers, such as colon cancer. Daily physical activity helps to lower blood pressure and cholesterol, helps prevent or retard osteoporosis, and helps reduce obesity, symptoms of anxiety and depression, and symptoms of arthritis.
