But Americans are sudsing up way too much. Compared to other well-off countries, people in the US admit to showering an average of around seven times a week -- like, every freaking day, sheesh -- which is more than the five times a week for people in China, Britain, and Japan. And while French and Spanish people shower around the same number of times as Americans, they shampoo much less frequently -- the French, for example, shampoo just twice per week.
The desire to be clean could backfire
All that bathing isn't just excessive compared to other developed nations; it can end up being worse for your skin and hair.
"Daily washing is not necessary for most people," dermatologist Dr. Tsippora Shainhouse says. "It washes off natural oils, and leaves skin dry and at risk for irritation." She recommends showering every other day. "This will help to rinse off dead skin cells and grease, as well as superficial bacteria and yeasts, which can lead to body odor, acne-type flares, and rashes in some people," she adds. You only need to shower more frequently if you work a physically strenuous job, or exercise for an hour every day.
