This Is Your Brain on Exercise

Cognitive and mood benefits of exercise, plus strategies for success.

“This is your brain on drugs. Any questions?”

Such a powerful slogan from the anti-narcotics campaign that debuted in the late 1980's. There were different versions of the public service announcement, but they all involved an egg and a frying pan. A vivid image and message that sticks with me to this day.

Drugs and exercise have at least one thing in common — they both have a significant effect on our brain.

As a psychologist, if I was told I only had one word to help someone who was struggling with their mood, it would be “exercise.” Physical activity is vital for brain health. We live longer, feel better, and our brains function more efficiently with exercise.

With exercise, the body releases endorphins which improves your mood. This in turn increases your motivation and energy to engage in other enjoyable activities (hanging out with friends, journaling, meditating) which further enhances mood.

All of these behavioral changes work together to fight depression. Physical activity starts a virtuous cycle of health.

Restorative sleep is crucial to our health. During sleep, the body repairs muscles and tissues, releases human growth hormone, and replenishes energy stores for the next day. When you sleep well, you feel better both physically and emotionally. A great starting point for improving sleep is exercise.
