“Showering for longer periods of time—or longer than 15 minutes—can adversely affect your skin, hair, and nails over time by over-drying them,” explains Anna H. Chacon, MD, a board-certified dermatologist and medical expert for ZELEN Life. According to Chacon, the ideal shower should only last around 5 to 15 minutes and should only be done once a day, at most. After all, showering is important to “maintain the health of your skin, hair and nails,” but showering incorrectly can also create problems. Jill Canes, NP, a nurse practitioner with more than 14 years of experience and founder of Face Forward Medical Aesthetics, says that even in lukewarm temperatures, long showers can dry out your skin by stripping away your skin’s natural oils. She says this causes your pores to open up, which allows moisture to escape, and then your skin may start to feel tighter and could even crack, if severely dehydrated. If you want to take longer showers, Cheryl Woodman, a skincare expert and formula scientist, says that you should absolutely turn the heat dial down. That’s because “cooler water reduces the negative effects of water on skin,” she explains. But just because the water is colder doesn’t mean you can spend too long in the shower, either. Woodman says a clear sign you’ve been in the shower too long is that your skin feels squeaky clean or tight afterwards. This can mean that “your skin barrier health is reduced,” which can actually leave you vulnerable to infection. Taking a long shower isn’t the only issue that can lead to infection-prone dry skin, however.
