Jakarta, ThedailyID — Regular physical activity does more than strengthen children’s bodies. Scientific studies suggest it can also improve brain function, increase intelligence, and support better academic performance.
Researchers found that children who exercise consistently tend to perform better on cognitive tests. Physical activity improves blood flow to the brain, delivering more oxygen and nutrients that support learning, memory, and concentration.
Exercise also stimulates the release of brain-derived neurotrophic factor (BDNF), often called the brain’s “growth fertilizer.” This protein helps build new brain cells and strengthens connections between neurons, making learning more effective.
Several studies have linked regular exercise to higher IQ scores and improved executive function. These skills include problem-solving, decision-making, self-control, and the ability to focus on complex tasks.
In addition, children who stay physically active often show better academic achievement. Experts say exercise enhances attention span and information processing, allowing students to absorb lessons more efficiently.
The benefits extend beyond intelligence. Physical activity helps reduce stress and anxiety while improving mood through the release of endorphins. Children who exercise regularly also tend to sleep better, which further supports healthy brain development.
Health experts recommend that school-age children get at least 60 minutes of moderate to vigorous physical activity every day. Activities such as cycling, swimming, football, basketball, dancing, and simply playing outdoors can all contribute to healthy cognitive development.
Parents do not need to enroll children in intensive sports programs to gain these benefits. Encouraging daily movement and reducing excessive screen time can already make a meaningful difference.
Experts emphasize that exercise alone does not determine a child’s intelligence. Genetics, nutrition, quality education, sleep, and a supportive home environment all play important roles. However, staying active remains one of the simplest and most effective habits to support both physical health and brain development.
