I prefer to keep my jewelry on but it depends. I am a side sleeper so no earrings to bed, I take off all rings before bed as well because my fingers swell at night.
I wear a DBTY look alike from BabyGold all the time; I got it six months ago and I take it off once a week to clean it. If a necklace is short in length and light I will leave it on.
I can leave most bracelets on if they are on my left wrist; I tend to tuck my right arm under my pillow and would be worried about messing up a bracelet but for some reason when I sleep on my left side I always lay my left arm out straight so anything on my left wrist is fine and dandy lol!
I wear a traditional “slide over the hand” bangle on my left and I never remove that as when I have done that in the past to other bangles, it has gotten warped and bent out of shape so that one never leaves my wrist. The other 2 bracelets I am wearing on the left are memory wire, so I prefer to leave them on so that they don’t get warped either. And the 4th bracelet I wear is hinged, so I take it off once a week to clean it.
If I were planning on cooking something that involved my using my hands like dough, swimming in the ocean or pool, or doing some manual labor then I do remove my jewelry.
