this is something i didn't realize until recently, but you really gotta be on washing that shit weekly. i used to think it wasn't a big deal, you could just do it every couple of weeks / once a month, but you sleep WAY better when you wash them weekly because your body and skin don't have to hold off a trillion bacteria trying to get into your body / getting allergies triggered by dust mites

although, to be honest, i would never have figured that out without dealing with a persistent vaginal infection because of it... 😭 at least i'm like 95% sure that's the cause atm. i guess i'll edit my comment in two months when i can confirm it (i'm testing this as of about a week rn)
