If you hate showering you’ll want to listen up. Researchers from Columbia University have found showering excessively can reduce skin hydration, causing it to become dry and cracked, which allows germs to enter. Study leader Dr. Elaine Larson says most people bathe in the belief that it will reduce their risk of illness, but in reality it doesn’t do much more than get rid of body odor. Dr. Brand Mitchell with George Washington University adds, “Your body is naturally a well-oiled machine. I think most people over-bathe,” and urges people who wish to shower daily to only do so if their skin feels healthy and hydrated.
