I know I could google this question, but I thought I would ask it here anyhow.
My oldest son is a freshman in high school. He plays baseball and football. Football season will be starting in 5 weeks. Now, would it be wise to come home from a physical practice and jump in 102° water and relax the muscles? How about after a game? I've heard of getting in a bath tub full of ice water after a game, so would this be a bad idea to heat up afterwards?
