But keep in mind that silver jewelry is softer than gold, platinum and titanium, and it's likely to tarnish without proper care. Do not store jewelry in the bathroom. Keeping pieces stored in individual plastic bags will help prevent oxidation and scratches. Store outside of the bathroom to avoid the steam and humidity dulling or rusting them prematurely. ... The humid environment will speed up the oxidation process and cause jewelry to tarnish faster. "The accumulation of dirt, bacteria, oil or fogging in jewelry can affect your skin," says Dr. Peredo of Quora... But there is at least one good reason not to sleep on your jewelry. "Wearing your jewelry while you sleep is the number one cause of losing precious stones and abrading the barbs!"
