Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health. ... If you have certain allergies or especially oily skin, it may be a good idea to shower more often.
Is showering every day necessary?
While there is no ideal frequency, experts suggest that showering several times per week is plenty for most people (unless you are grimy, sweaty, or have other reasons to shower more often). Short showers (lasting three or four minutes) with a focus on the armpits and groin may suffice.
How often should I take a shower?
It may sound counterproductive, but a shower every day could be bad for your skin. Some dermatologists only recommend a shower every other day, or two to three times a week. Many people hit the shower at least once a day, either in the morning or at night before bed.
