Psychiatrist and Harvard professor, John Ratey, calls exercise the single most important tool people have to optimize brain function. If you get your body in shape, he says, your mind will follow
His theory is straightforward: Humans evolved as physical creatures. When they're lulled into sedentary lives, their bodies -- and their brains -- get flabby from lack of physical exertion.
Exercise, particularly aerobic exercise, can improve cognitive performance, soften the effects of stress, help fend off addiction-related cravings and tone down the negative consequences of women's hormonal changes.
Trish, I have noticed the diference between not exercising and exciercising. When I don't workout for a week to two week period I get into a lazy rut and all I want to is do is watch T.V. I also get more emotional. But when I work out I am more alert and work doesn't effect me as much. One thing that sticks out when I don't work out I want to "drink" more as to when I do work out I don't have those desires. So Yes exercise is good for the brain.
