Showering too often is not recommended!
Especially in Spain, a daily shower is usual. Some people even shower 2 or 3 times a day. But, should we shower every day? No, on the contrary, a shower a day with hot water and soap damages considerably our skin. I often see patients who come to see me because their skin is too dry, with eczema, stinging, allergic reactions or with the sensation that their skin is very tight. Our skin has a natural layer of fat that provides hydration, flexibility and nutrients. It is our protection against fungus and bacterias. We destroy it when we shower with hot water and soap and even more so when we use a rough sponge or an exfoliating glove. We open the door to pathogens.
In other words, excessive hygiene is almost as bad as the lack of it. There is no doubt about the fact that we should wash off our sweat after we have a physical activity or the dust after working outdoors, but no more than that. Soap should be used with moderation as well: if we need to use it because of dirt or sweat, we should use soap with neutral pH in order not to damage the skin. A daily wash of our armpits, genital area and feet with a soft cloth or sponge and a short shower with lukewarm water is sufficient to be clean and well groomed.
