Thanks Dimitre! It's so special to be recognized for my sense of humor! As for your question - I agree 100% with your GP. I can honestly tell you that cold showers are less dangerous than sugar, alcohol, and driving. So, if you are willing to take those risks, you are likely going to be ok taking a cold shower. I also am a big believer in self-experimentation. I personally have not had or read about negative side effects but you should definitely verify it for yourself and report back!
