Kelly Mieloch, 42, said that since the pandemic began she had showered only “every couple of days.” What is the point of daily showers, she said, when she rarely leaves the house except to run errands like taking her 6-year-old daughter to school? “They’re not smelling me — they don’t know what’s happening,” Ms. Mieloch said. “Most of the time, I’m not even wearing a bra.” What’s more, she said her decision to stop daily showers had helped her appearance. “I just feel like my hair is better, my skin is better and my face is not so dry,” said Ms. Mieloch, a mortgage loan closer in Asheville, N.C.
