I heard about cold showers being good for you but...not sure if I could do it. If my life depended on it, I would but now...not sure. I do have to say that I dislike hot showers...I tend to shower with luke warm water which my husband describes as cold. LOL (he takes incredibly hot showers...he sometimes looks like a lobster when he comes out of the shower) I might have to try to shower with even colder water and see if I like it
