Physical activity is crucial for their health. Regular physical activity helps build and maintain healthy muscles, bones and joints. It helps control weight, reduce fat and build lean body mass. It also helps children burn off excess energy and has been shown to help reduce feelings of depression and anxiety. Activities that decrease stress hormone production, as exercise does, are important in our stress-laden society-even for children. As a bonus, when kids are physically strong and don’t feel restless, depressed or anxious, they do better in school and have fewer behavioural problems.
