I fell into a discussion of how often folks change their bedsheets only to find I'm in the minority. I change mine weekly. Others in the conversation ranged from weekly, to biweekly, to monthly, to "about 5 or 6 times a year." I'm glad they couldn't see my facial expressions. My skin doesn't like it if I sleep on sheets for more than a week or so. It's hard to sleep when your dermatitis is flaring up.
@divisionbyzero Weekly. Sometimes more frequently. I do not want to know those other people.
@divisionbyzero Every Sunday new sheets (sometimes even more often - depending on weather and sweat factor). How sad people think that "monthly" is hygienic! Ugh!
