Keeping our brains in good shape isn’t just about solving puzzles or learning new skills – it’s also about moving our bodies! A new study published in the International Journal of Behavioral Nutrition and Physical Activity shows this moderate and intense physical activity can significantly improve memory and brain power for up to 24 hours. Here’s everything we need to know about what it means and how it works in simple, everyday terms.
Brain power amplifier
When we exercise, our heart pumps more blood, which carries oxygen and nutrients to the brain. Not only does it give you energy, but it also helps improve your memory and thinking skills.
76 people between the ages of 50 and 83 took part in the study. It found that on days when participants engaged in moderate to vigorous activity, such as brisk walking or dancing, they performed better on memory tests the very next day. So the brain stimulation from exercise isn’t just short-lived; it may last much longer than we previously thought.
Lead author Dr Michaela Blumberg explains: “Anything that gets your heart rate up, like climbing stairs or going for a brisk jog, can have a big impact on your brain. And the benefits last much longer than a few hours after your workout.”
How Exercise Recharges Your Brain
So why does exercise have such a powerful effect? It’s all about what happens in your brain when you move.
1. Better blood flow
Exercise improves blood circulation to your brain, delivering more oxygen and nutrients to help it function at its best.
2. Feel-good chemicals
Physical activity causes the release of brain chemicals such as dopamine and norepinephrine. They help focus, improve mood and improve memory.
3. Connecting to deep sleep
The study also found that exercise improves the quality of sleep, especially deep (slow-wave) sleep. This is when your brain processes memories and restores itself, giving us additional cognitive benefits.
4. The benefits of memory are more than temporary
Most studies show that exercise gives your brain a short-term boost, but this highlights something fascinating: The benefits can last into the next day.
How to start
The best part? You don’t have to hit the gym or run a marathon to enjoy these benefits. Start small with activities you enjoy:
No equipment required: 15 minute full body workout at home
- Go for a short walk in your neighborhood or a park.
- Dance to your favorite tunes!
- Take the stairs instead of the elevator.
- Try yoga for a combination of physical activity and relaxation.
This moderate exercise not only improves your physical health, but also does wonders for your brain.
