Cleanliness: Bedroom, Sleeping area

IN THE BEDROOM
Now for suggestions in bedroom care:
If you sleep on a futon, the floor should be wiped after folding and putting the bedding away, a habit I was taught in my woman's asrama days. In any case, wiping the bedroom floor daily is a good habit.
If you sleep on a regular bed, it is a good idea to fix the bed right after getting up. 
Fluff pillows or put them out in fresh air and sunshine to freshen.
Whenever possible, hang bedding outside or at least once a month.
Flip the mattress over once a month for even wear.
I was initially trained to wash my sheets daily, but now washing takes place at least once a week. 
It's important to sleep with a top sheet or duvet to prolong cleanliness and the life of a blanket. 
Preferably, change into clean bedclothes before sleeping. 

A SIMPLE BEDMAKING SUGGESTION
1. Lift up and shake out the bottom or fitted sheet from the lower end of the bed, then tuck or fit it securely and smoothly once again. 
Here's the old fashioned way to secure the corners of a sheet when there is no fitted sheet:

2. Fluff the pillows. 
3. Fold the blanket used and put it away or carefully fold and place it at the foot of the bed. 

Ideally, the blanket should have a washable cover or duvet. Then an additional top sheet becomes unnecessary. The blanket also should be aired out often on sunny days.
4. Finally, smooth the bed skirt at the bottom of the bed (if any).
