Dr Browning says your bedroom should be a "sanctuary" for sleep, and "a wonderful, pleasant place where we feel happy".
I take serious exception to this concept. Most people can't afford to have a room set aside as some sort of sleep fantasy world. There is a global housing crisis going on. Rooms are multi purpose. People live in bedrooms, sleep in living rooms.
Sometimes i will go a month without washing my sheets. I have extra sets so i can immediately put on fresh sheets, but it's such a shitty and time consuming chore and I hate it. Laundry is the worst chore, but you reach a point where you have to clean your clothes because you have no clean underwear. Bedding is easier to convince yourself you dont really need to do.
Roughly, I suppose. Between a somewhat dirty job and a hobby of running, I do a lot of laundry as it is. Factor in me being the cook of the house and as politically involved as I can, some stuff is neglected. I'd say 4-5 times a year in my case, though.
