We are experiencing a heat wave in California as I write this. While working I take frequent breaks to cool off. I have found that putting my trunks on and hosing myself off or running through the sprinklers has the same effect as jumping in the ocean or hopping in a pool. A cold shower works, too. (No, I don’t have air conditioning, but wish I did right now.)
It just goes to show that we can get the feeling of doing something big by doing a smaller version of it (swimming in a pool versus making it rain with a hose) the aftermath is the same (we’re outside, wet, and cooled off).
