Why exercise?

Good exercise, meaning a kind that suits YOU, can help reduce your stress and lift your mood. Exercise that you actually LIKE to do, and not one you feel you HAVE to do, is chemically as good for your nervous system as an antidepressant that doesn't cause you side effects. It is somewhat cheaper too ;-) But of course it is hard to get off the couch to go exercise when you do feel down and depressed and don't feel there's any point in doing much else. But knowing that you can help low mood pass might be useful.

Here's an encouraging  booklet that has some good information about exercise.
