After the death of two very close friends and a lot of stress, I ended up with stress induced psoriasis all over my head, neck and shoulder. I tried EVERYTHING OTC and nothing worked so finally, I gave up, and started saving money to go to the doctor. I came across the cold water therapy on this site and although I did not intend to use it to treat this issue, it sure cured it. I started taking cold water showers in the hottest months here in Virginia. Immediately I noticed the increase in energy and my hair is SUPER SOFT even after months of harsh psoriasis shampoos that had my hair turning to straw. Call me crazy, but it seems my shower doesn't get as grimy as it did before when I was using hot water. My complexion has improved, and there is an obvious difference in my pores. Basically, I have nothing bad to say about cold showers. After 2 months of them, I can't even STAND a hot shower now.
