According to most dermatologists, the ideal shower temperature is anywhere between 98°F (37°C) and 104°F (40°C)—and no more than 105 °F (41°C). Rinsing under lukewarm water allows you to stay comfortable and maintain your body temperature while reaping all the benefits of both hot and cold showers.
But this general rule doesn’t mean you should stop taking cold or hot showers. In fact, the water temperature you use can deliver different health impacts, so varying your routine can be really beneficial.
