Re: Dousing with cold water: Who does it?
I've never done it for medicinal reasons... but yeah, I know the feeling. =)
I've read that submerging the face in cold water triggers a reflex response. Various mood and physical altering chemicals, the constriction of blood vessles, etc. Whether or not this is good I don't know, but it's certainly a documented effect. (Is there a brain surgeon in the house?)
Reasoning aside, I've always been of the opinion that a little shock does a body good.
