Showering daily is not necessary according to Stephen Shumack, the president of the Australasian College of Dermatologists. Showering too much can have negative consequences on hair and skin such as causing split-ends, building up of products and washing away of natural oils, so bathing should only be done when needed.
Shumack claimed that the idea of showering daily has become prevalent only in the last 50 to 60 years. People feel the need to shower out of social pressure rather than actual need, as the social need to smell good is crucial.
It’s only in the armpit and groin that body odors are emitted, contrary to some beliefs that the stench is produced all over the body. Because of this, people are actually doing more damage than good, risking themselves from “defatting” or rinsing oneself of the body oils which are important to protect skin cells and keep the skin moisturized.
Consequently, people who have done too much defatting make themselves more prone to bacteria or viruses and itchy, dry and flaky skin. In fact, this practice may even exacerbate skin conditions such as eczema.
Other experts agree with Shumack’s advice. John Oxford, professor of Virology at Queen Mary’s School of Medicine and Dentistry, said that as long as people are focusing on the right areas, showering too often is not of utmost importance.
The professor added that washing the hands and cleaning the area below the belt would suffice. If everyone does this, showering every other day is good enough.
Interestingly, a survey conducted in 2015 showed that four out of five women do not shower every day and a third claimed to go three days without washing. In another study, three-quarters of the participants of a study by the researchers at the Universities of Manchester, Edinburgh, Lancaster and Southampton, say that they shower at least once a day.
