According to Marina Peredo, M.D., F.A.A.D, Associate Clinical Professor of Dermatology at Mount Sinai Hospital in New York and founder of Marina I. Peredo, M.D., P.C. Dermatology and Spatique Medical Spa in Smithtown, N.Y., continuously wearing jewelry really isn't a big deal -- as long as you clean it regularly and the materials don't irritate your skin. "You can potentially damage your jewelry by constantly wearing it, but there are no major health risks to wearing jewelry every day, which includes sleeping and showering," she says. Although "metals that are added to gold and silver such as nickel can be extremely irritating to the skin," says Dr. Peredo. We suggest removing your jewelry for sleeping to avoid any inconvenience.
