While cold water or ice baths might work for some, I believe it is a basic fact that cold slows circulation and warmth enhances it. Think stories you've read about drowning victims in winter surviving because the cold slowed their bodily functions. Think cancer patient stories of avoiding hair loss or neuropathy by using cold caps or mitts to reduce the amount of chemo drugs to the scalp, hands or feet. You'll find stories of the latter here on Connect.
