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.
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.
In general, showering every other day or every few days is enough for most people. Keep in mind that showering twice a day or frequently taking hot or long showers can strip your skin of important oils. This can lead to dry, itchy skin.
According to Shirley Chi, MD, a board-certified dermatologist in Los Angeles, there isn't a one-size-fits-all approach. Showering "once every three days is fine." If you have a skin condition, the answer is different, however.
When you skip showering for a couple days, it can lead to your body releasing potentially unpleasant odors. Dr. Muhammad says, “Body odors form naturally as a result of bacteria on the skin breaking sweat down into acid. By not washing while continuing to sweat, bad smells will just get worse and worse.”
"Showering less helps strengthen your immune system by keeping disease-fighting bacteria living on your skin. It also allows us to preserve more of our microorganisms and the skin's natural oils," she says.
“Humans tend to perspire at night,” Dr. Goldenberg said. “When you wake up in the morning, there's all this sweat and bacteria from the sheets that's just kind of sitting there on your skin.” So take a quick shower in the morning, he said, “to wash all of that gunk and sweat off that you've been sleeping in all night.”
There's no one-size-fits-all answer to this question. 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.
Occasionally, the refusal to shower could be linked to certain mental health problems. For example, teens with serious depression may lack the interest and energy to shower. 2 But taking a shower won't be the only problem they'll struggle with; depression could also lead to academic and social problems.
In the United States, most people bathe daily but, in other countries, many people bathe only 2-3 times per week or less. Many times it can come down to habit and ritual, as daily showers can help people feel more awake, avoid body odor, relax tight muscles or simply because that's what they've been taught to do.
Dead skin cells, bacteria, and even sweat can accumulate quickly on your towels, so using a fresh one about every three days is a simple rule of thumb—for all kinds of towels. You can of course change them more often.
A daily shower isn't necessary. ' Mitchell suggested showering or bathing once or twice a week, and experts generally say a few times a week rather than daily is plenty. Also, keep showers short and lukewarm, as too much water, particularly hot water, dries out the skin.
If you don't wash your body, it makes it easier for germs that cause actual skin infections to flourish. If you didn't wash at all, dirt, sweat, dead skin cells and oil would start to accumulate, and infections or ongoing skin conditions can become more serious, more difficult to manage, and harder to undo.
"The average individual can typically go 2 to 3 days without shampooing their hair. However, if your hair is visibly oily, you may not want to wait that long," she says. "Usually, you can go longer without washing your hair when your hair is styled up, but no one should ever go more than 14 days."
When incorporated into a bedtime routine, a nighttime shower may help send your brain the signal that it is time to sleep. Showering at night also ensures you will be cleaner when you go to bed, reducing the buildup of sweat, dirt, and body oils on your bedding.
Benefits of Showering in the Morning
Another benefit to morning showers is that you cleanse yourself of any night bacteria. Research shows that humans tend to sweat more at night than in the morning. A quick morning shower can help you feel less sweaty.
Cold showers can help reduce inflammation, relieve pain, improve circulation, lower stress levels, and reduce muscle soreness and fatigue. Hot showers, meanwhile, can improve cardiovascular health, soothe stiff joints, and improve sleep.
Rokhsar said your stench likely would come as a result of the bacteria and dead skin accumulating on you. After a year, he said, you'd have a build-up of skin stratum corneum, or dead skin on top of your skin. It includes a build-up of a protein our skin produces that has a funky odor to it.
