If you're showering every day, you're probably over doing it. In fact, showering too often can actually hurt your body in the long run.
As Time's public health column explains, daily showers are common due to social norms more than any proper health need. We connect being freshly showered with being attractive and pleasing, so we tend to showering often to feel better.
But what's the ideal shower frequency? In terms of your health — not how you look or smell — probably once or twice a week, assistant professor of dermatology at George Washington University, Dr. C. Brandon Mitchell says. “Your body is naturally a well-oiled machine,” he says. “A daily shower isn't necessary.”
Of course, your situation may vary. If you have a job like car maintenance or construction, you'll obviously have a visible layer of dirt you'll need to wash off every single day. Similarly, if you work out every day, you may not have any health risks by washing every day, but you'll still be smelly. If you feel like you need to take daily showers for aesthetic（审美的）reasons, at least make most of them light showers. “I tell patients who shower daily not to soap their whole bodies,” Mitchell says. Hit your pits, butt and groin, which are the areas that produce strong smells. The rest of your body doesn't need much soaping, he says.
Too much time spent under the hot water can dry out your skin, cause cracks（裂纹）that can lead to infections or germs getting into your skin, and take away the natural oils on your skin that help keep it healthy. So, even if you're aiming to be your most presentable, be sure to keep it moderate to avoid hurting your skin in the long run.
