I have been going to an outdoor pool with the kids a lot this summer. At first I was very apprehensive. A pool with lots of screaming kids was a guaranteed headache I thought. Surprisingly, it's almost turned out to have the opposite effect. Sometimes I arrive with a slight headache, and it disappears after jumping in the cool, refreshing water.... despite the fact I'm surrounded by kids yelling, splashing, and clinging to me. I've found it very therapeutic, as others have mentioned.
