How does physical activity influence children's health?

Physical activity has significant benefits for children's health, and one of the most important is its ability to enhance heart and lung capacity. Engaging in regular exercise outside boosts cardiovascular endurance and improves the efficiency of the lungs. This leads to better oxygenation of the body, supports overall physical health, and contributes to a healthier immune system.

Moreover, increased heart and lung capacity allows children to participate more fully in various activities, including sports and play, which further encourages an active lifestyle and social interaction with peers. By fostering physical health, regular activity also lays the groundwork for healthy habits later in life.

The other options suggest negative consequences or misunderstandings about physical activity. Fatigue can occur after excessive exercise without proper recovery, but moderate activity generally results in increased energy levels. The assertion that it prevents friendships ignores the social interactions that often flourish through group activities and sports. Lastly, the idea that it keeps children indoors runs counter to the fundamental nature of physical play, which typically occurs in outdoor settings.
