Cleanliness is next to Godliness, or so the saying goes. But if you're someone who finds their morning scrub unnecessary, new findings suggest it may well be.
Whilst we are all brought up to believe that washing daily is just common decency, experts are now suggesting you may only need to do so once or twice a week.
Dr. Elaine Larson, infectious disease expert at Columbia University School of Nursing told Time: "I think showering is mostly for aesthetic reasons. People think they're showering for hygiene or to be cleaner, but bacteriologically, that's not the case."
She also said that while washing is necessary to remove odours after exercise or perspiring in heat, it won't necessarily help with protecting from illness. Her advice? Making sure you wash your hands which should be enough. Unless you're regularly rolling around in mud.
Further evidence damming regular bathing suggests that it in fact dries up your skin, opening gaps for germs to enter your pores.
"Your body is naturally a well-oiled machine. A daily shower isn't necessary," said Dr. C. Brandon Mitchell, assistant professor of Dermatology at George Washington University. He found in studies that washing too frequently disrupted the skin's process of fighting bacteria and stripped away natural oils.
That said, to the guy on the tube that everyone can smell two carriages away: deodorant is still not optional.
