I started taking cold showers (very cold) about a month ago due to high gas bills. I have also done some research on the topic and have found that many cultures from India to Russia have practiced this for hundreds of years. Russian boxers do this for toughing up the skin before a fight and as the topic above Indians have been practicing this for health benefits mental and physical. The most dramatic benefit I have found is sense of smell. I never realized how smelly hot water is. Also after taking a warm shower, you smell as if you didn't clean yourself an hour later. Start taking cold showers help yourself and the environment!
