Ways exercise helps your brain stay in shape 
  • Memory. Do you have a big test you’re preparing for? Try exercising a few hours after studying.  
    • Exercising after you study can improve your ability to retain information.  
    • Regular exercise increases the volume of your prefrontal cortex, which is the area in the brain that deals with memory and thinking.  
    • Exercise can help lower risk of dementia, a condition related to memory loss. 
  • Mental health. Studies show exercise can help reduce symptoms of depression and anxiety. Specifically, exercise reduces cortisol in the body, the body’s stress hormone. It also stimulates the production of endorphins, the body’s natural mood elevators, in the brain. However, if you think you might be experiencing symptoms of depression or another mental health condition, make sure to talk to a health professional.  
  • Overall wellness. Regular exercise can help you sleep better, increase your energy level, and offer mental health benefits. Exercise helps you feel better all around – not just physically.
