So how often do you change your bedding it has come to light I am either a cleaning freek at once week or some of my work colleagues are filthy scumbags at month or more !
I have a pile of sacks that I sleep in. Every few days I just grab a new one and throw the old one away.
Once a week. I do have a friend who changes hers every day, she must be particularly sweaty.
(Tbh if I wasn't married or lived on my own it wouldn't be once a week...)
