Dr. Adam Friedman, professor and chair of dermatology at George Washington School of Medicine and Health Sciences, also pointed to the limited science around contrast showers and warned against the potential for thermal burns if you aren’t careful.
“I don’t know how big a problem this is, but I would be concerned about the potential for burning the skin,” he said. “Cold showers can have a mild anesthetic component, so when you flip the switch and turn to hot water, you could potentially expose yourself to water that is hotter than you realize.”
Friedman noted that the cycling of extremes puts stress on the body, which could have potentially negative consequences.
