Here's sad news for everyone who likes to linger in a hot shower or bath: Hot water strips the natural oils from your skin. While that might sound like a great idea if you have oily skin, hang on. Hot water also causes your skin to lose moisture. The result of your relaxing bath? Add flaky, rough patches to already oily, acne-prone skin.
How is it that you could lose skin moisture while sitting in a hot bath? Water that's hotter than 100 degrees Fahrenheit (37.8 degrees Celsius) may be a luxurious bath, but when your body temperature begins to climb, your body instinctively tries to cool off. The sympathetic nervous system responds to the heat by dilating the blood vessels in the skin in an effort to lower the body's temperature. That's a fancy way of saying the body senses it's too hot and is trying to cool off -- kiss your skin's hydration goodbye at the hands of evaporation.
Water temperatures that are between 85 to 95 degrees Fahrenheit (29.4 to 35 degrees Celsius) -- or even room temperature if you can handle it -- are optimal for keeping skin hydrated and healthy. Keep showers short, and keep face washing to less than one to two minutes.
