Did you know that exercise such as a simple jog or a bike ride could actually boost your brainpower?
In the first chapter of Spark by Dr. John Ratey, we learn that exercise isn’t just for fitness — it’s fuel for your brain. Dr. Ratey introduces Naperville Central High School in the U.S., where students who exercised before class consistently outperformed others in academic tests. Their secret? Movement. Not just a casual walk either. They had to move and exercise by increasing their heart rate to a specific level. This then increased the lay down of BDNf (Brain Derived Neurotrophic factor), which in turn help to lay down new neural pathways essential for learning.
Here’s why exercise helps your brain:
Increases learning capacity: Exercise stimulates the production of Brain-Derived Neurotrophic Factor (BDNF), a chemical that helps brain cells grow and connect — think of it as “fertiliser for your brain.”
Improves focus and mood: Physical activity balances hormones like dopamine and serotonin, helping you stay calm, focused, and happier — especially important during exams!
Reduces stress and anxiety: Moving your body helps burn off stress hormones like cortisol, making you more resilient and emotionally balanced.
Bottom line: Exercise is one of the most powerful tools you have to improve memory, learning, mood, and even academic results.
Tip: Try starting your day with 20 minutes of moderate movement — walk, run, skip rope, HIIT, dance, anything that gets your heart rate up. Your brain will thank you.
