Ever had that lazy Saturday or Sunday when you just can’t motivate yourself to get off the couch and into the shower? Don’t sweat it. “Long, hot showers and harsh soaps can destroy the natural oils that keep the skin moisturized and maintain its barrier function,” says Jill Weinstein, M.D., a dermatologist at Northwestern Memorial Physicians Group. “This, in turn, can make the skin dry and sensitive.” Weinstein recommends keeping showers short (10 minutes tops), and using warm rather than scalding-hot water. And as long as you’ve brushed your teeth, it’s OK to skip that weekend-morning shower—granted your only plans that day are watching the game at home.
