Keeping our brain sharp isn’t just about solving puzzles or learning new skills—it’s also about moving our body! A new study published in the International Journal of Behavioral Nutrition and Physical Activity reveals that doing moderate to vigorous exercise can greatly improve memory and brain power for up to 24 hours. Here is all we need to know about what this means and how it works in simple, everyday terms.
The brain’s power booster
When we exercise, our heart pumps more blood, which carries oxygen and nutrients to the brain. This doesn’t just make you feel energised—it also helps improve memory and thinking skills.
The study looked at 76 people aged 50 to 83. It was found that on days when participants did moderate to vigorous activities like brisk walking or dancing, they scored better on memory tests just the next day. So, the brain boost from exercise isn’t just short-lived; it can last much longer than we previously thought.
Lead author Dr Mikaela Bloomberg explains, “Anything that gets your heart rate up—like climbing stairs or a quick jog—can make a big difference for your brain. And the benefits extend well beyond a few hours after exercising.”
How exercise supercharges your brain
So, why does exercise have such a powerful effect? It’s all about what happens inside your brain when you move.
1. Better blood flow
Exercise increases blood circulation to your brain, delivering more oxygen and nutrients to help it function at its best.
2. Feel-good chemicals
Physical activity triggers the release of brain chemicals like dopamine and norepinephrine. These help you stay focused, improve your mood, and enhance memory.
3. Deep sleep connection
The study also showed that exercise improves sleep quality, particularly deep (slow-wave) sleep. This is when your brain processes memories and repairs itself, giving us an extra cognitive edge.
4. Memory benefits are more than temporary
Most studies suggest that exercise gives your brain a short-term boost, but this one highlights something exciting: the benefits can last until the next day.
How to get started
The best part? You don’t need to hit the gym or run a marathon to enjoy these benefits. Start small with activities that you enjoy:
No equipment needed: 15 minutes full body workout at home
- Go for a short walk in your neighbourhood or park.
- Dance to your favourite tunes!
- Climb stairs instead of taking the elevator.
- Try yoga for a mix of physical activity and relaxation.
These moderate exercises not only improve your physical health but also work wonders for your brain.
