Exercise helps you focus.
For 2 to 3 hours after a workout, it’s much easier to focus on the task at hand.
You can think far more clearly after a run, that if you have a difficult problem to work through, this is when you want to do it.
Exercise has also been shown to help slow down the effects of Alzheimer’s Disease.
The way exercise is helping your mind is to improve the blood flow in the brain, providing more oxygen, and helping to move hormones and brain chemicals around properly.
