Active Body, Active Mind: The Role of Physical Activity

It’s often said that a healthy body supports a healthy mind– and science backs this up. Physical activity isn’t just good for teens’ muscles and hearts; it also benefits their brain function, mood, and even academic achievement. When teens get moving, their circulation improves, delivering more oxygen and nutrients to the brain. Over the past several years, multiple studies have found a positive relationship between regular exercise and cognitive performance in youth pmc.ncbi.nlm.nih.govnature.com. For example, one 2024 study of adolescents showed that better overall physical fitness was linked to better concentration and attention in cognitive tests – in fact, fitness differences explained about 26% of the variation in attention performance among students nature.com. In another analysis, researchers noted that even a moderate amount of exercise (around 90 minutes per week of at least moderate intensity) was associated with improved academic performance in school children pmc.ncbi.nlm.nih.gov. The effect may be especially pronounced for students who struggle initially: one large survey found that physical activity significantly boosted cognitive ability in teens, with the biggest gains seen in those who started with lower cognitive scores. In short, staying active helps sharpen thinking skills like concentration, memory, and processing speed – all of which are vital for learning.

Beyond direct cognitive benefits, exercise also improves mental health and academic motivation. Physical activity triggers the release of endorphins and other brain chemicals that can reduce stress and anxiety. A teen who goes for a run or plays basketball after school might find they feel less tense and more ready to focus when it’s time to hit the books again. Overtime, active teens often have better mood and higher self-esteem, which can translate into a more positive attitude toward school. There’s even evidence that regular exercise can improve self-regulation and discipline –skills that help with everything from resisting the temptation of video games before homework to persisting through challenging assignments. And importantly, being physically tired (in a healthy way) by the end of the day can promote better sleep, creating a virtuous cycle: exercise leads to better sleep, which leads to better focus the next day. All of these factors combined explain why kids who meet the recommended activity levels often do better academically than their sedentary peers.

Tips for Keeping Teens Active: Encourage your teen to get at least 60 minutes of moderate to vigorous physical activity each day (the guideline for youth fitness). This could include sports practice, a brisk walk or bike ride, dancing, swimming, or even active video games – anything that gets their heart rate up. If your teen isn’t into team sports, help them find a physical hobby they enjoy, such as martial arts, skating, or doing a workout at the gym. Make movement a normal part of their routine: for example, they could walk the dog after school or do a quick set of exercises during a study break. You can also promote activity by limiting very long stretches of sitting – suggest they stand up and stretch when studying or take a short walk around the block after finishing a chapter of reading. Remember that physical activity can be a family affair too: maybe take an evening stroll together or play a pick-up game of basketball on the weekends. The goal is to integrate activity into daily life so it doesn’t feel like a chore. By keeping their bodies active, teens will likely find their minds are more alert, their stress is lower, and their overall school performance improves as a result.
