Bathing every day could be bad for you

Bathing every day may not be necessary for everyone and, in some cases, could contribute to dry, irritated skin by stripping away the skin's natural protective oils, according to health and skincare experts.

Some artisanal miners in Zimbabwe even associate frequent bathing with bad luck, although medical experts say decisions about bathing should be guided by hygiene needs and skin health rather than superstition.

Research from institutions including the University of Nottingham's Eczema Bathing Study, Harvard Health and the Cleveland Clinic suggests that while personal hygiene is important, excessive washing - particularly with hot water and harsh soaps - can damage the skin's natural barrier and microbiome.

Zimbabwean experts say the ideal bathing frequency depends on a person's lifestyle, skin type and occupation.

Bulawayo-based biologist, biochemist and cosmetic chemist Mercy Mabiza said daily bathing is not biologically necessary for everyone.

"From both a biological and cosmetic science perspective, I agree that daily bathing is not biologically necessary for every individual.

"The skin is a living organ with its own microbiome and protective lipid barrier that naturally maintains skin health," she said.

Although Zimbabwe's warm climate often results in increased perspiration, Mabiza said maintaining the skin's natural protective functions is just as important as keeping clean.

"Very hot water and harsh soaps remove the skin's natural lipids, increase trans-epidermal water loss and weaken the skin barrier.

"Over time this can lead to dryness, irritation, sensitivity, eczema flare-ups and even premature skin ageing.

"When these oils are stripped away repeatedly, the skin becomes dry and vulnerable.

"In some people, the skin responds by producing even more oil, contributing to acne. In others, especially those with sensitive skin, it can result in inflammation, itching and increased sensitivity.

"Healthy skin is not about removing every trace of oil; it is about maintaining balance."

Renowned gynaecologist Dr Solwayo Ngwenya also said excessive bathing may not be beneficial for skin health.

"Even our forebears did not bath every day. Overbathing removes the skin's protective barrier.

"Just keep good hygiene and find the sweet spot between showers and maintaining the skin's healthy bacteria that keeps it healthy and glowing," he said.

He also cautioned against excessive intimate washing.

"Women also have a belief that they should scrub and douche their privates constantly. That is not necessary. Nature takes care of itself down there; using plain water is the best."

Dr Ngwenya added that people with eczema, psoriasis, sensitive skin and older adults often benefit from shorter, less frequent showers.

For those who prefer to bathe daily, he recommended limiting showers to between five and 10 minutes, using lukewarm rather than hot water, and applying moisturiser immediately afterwards. Products containing ceramides, glycerin, hyaluronic acid or natural plant oils can help restore the skin's moisture barrier.

Skincare specialist Gamuchirai Rejoice Charunduka said daily bathing may still be appropriate for some people, particularly those with oily skin or physically demanding jobs, provided they avoid prolonged hot showers.

"Our sebaceous glands produce oils throughout the day. When these oils accumulate, the pores become clogged, making it difficult for the skin to function properly.

"On the face this can contribute to acne," she said.

Traditional healer Mhabhinyana said bathing habits should reflect an individual's occupation.

"If someone does physically demanding work and sweats a lot, they should bath every day. If someone works where they do not sweat much, daily bathing may not be necessary," he said.

Artisanal miner Platini Nyathi said some gold panners believe bathing every day brings bad luck, illustrating how cultural beliefs continue to influence personal hygiene practices in some communities.

Health experts, however, agree that there is no universal bathing schedule. Instead, they recommend tailoring bathing habits to individual needs while avoiding practices that unnecessarily damage the skin's natural protective barrier.
