A Professor of Virology at Queen Mary's School of Medicine and Dentistry, told The Times: "As long as people wash their hands often enough and pay attention to the area of the body below the belt, showering or bathing every other day would do no harm.
"Even twice a week would not be a problem if people used a bidet daily as most infectious bugs hang around our lower halves.
"We pay too much attention to the body beautiful and smelling good, with perfumes for men and women," he added.
Of course, you shouldn't shun a wash after a sweaty run. The every-other-day rule is flexible depending on your lifestyle.
Take me, for example. I don't sweat any more, partly due to lack of exercise in my advancing years, but also because of a healthy diet. For ten years of so, I've showered on alternate days prompted by reading similar advice. My skin is dry already, particularly the lower legs, and I don't need to make it worse.
It seems over-bathing can dry out and irritate skin, washing away the good bacteria and even heightening risk of infection by causing small cracks in the skin. (Love that. Good bacteria, not sweat and oils.)
On the whole, advice from dermatologists shows we're bathing a lot more than we need to. Would you skip the daily shower to improve your skin?
