How Much Physical Activity and Sleep Do Children and Teens Need?
Physical Activity Recommendations
Children need at least 60 minutes of physical activity each day.
The activity should be age-appropriate and fun, and kids don’t need to fit it all in at once: They can add up physical activity throughout the day, in short bursts of 10 minutes or longer.
Children need to spend most of that hour in moderate- or vigorous-intensity aerobic activity—that is, activity that causes an increase in breathing and heart rate. Make sure children get vigorous-intensity aerobic activity on at least three days of the week.
Include muscle-strengthening and bone-strengthening activities on at least three days of the week.
