Aaaah, it's sure that a good bath or a good shower in the morning or in the evening after a long day at work is nirvana. We rinse all the problems of the day and we smell clean. But, in reality, to be clean, it would be enough to wash… between two and three times a week. Stephen Shumack, President of the Australian University of Dermatology explains that, contrary to what one might think, rubbing the epidermis every day does not protect against bacteria. On the contrary, by washing the skin every day, you risk weakening the skin barrier and, in the long term, it dries out and you can even develop eczema. He also insists that it is the glands under the arms and in the groin that produce odor, not the whole body. On the other hand, for the hands and the face it is different:it is imperative to wash them several times a day to protect yourself from the surrounding microbes. There is still a union minimum to do daily:a small cat toilet including the feet, intimate areas, armpits, faces and teeth. Well yes, it's complicated to consider arriving at work all stinky, on the pretext that it's better for your health!
