Research evidence suggests that children who are more physically active do better in school.
Exercising not only spikes brain activity and prepares you for mental stresses, but also increases the retention of new information and helps students to better react to complex situations. Just a single session of moderate exercise before school has been shown to benefit brain function and academic performance in children, while also producing healthy consequences in terms of mental health.
The benefits of exercise come directly from its ability to reduce insulin resistance, reduce inflammation, and stimulate the release of growth hormones—chemicals in the brain that affect the health and abundance of brain cells.
Exercise stimulates growth of new connections between these cells in a wide array of important areas of the brain, making it easier for the brain to grow new and strong connections during a learning process. Indirectly, exercise improves mood and sleep, and reduces stress and anxiety.
