Sheets and pillowcases
Sheets and pillowcases sit closest to your skin, so they collect dead skin cells, sweat and body oils. A weekly wash is the comfortable baseline. During Jeddah summers, when people sweat more and the air conditioner runs all night, every three to five days can be sensible for anyone with nasal allergies or asthma.
If the sleeper uses hair oil or night cream, a faint yellow shadow often appears on the pillowcase over time. Washing early makes those marks far easier to remove, because oxidised oil bonds to the fibre and becomes stubborn when left for weeks.
Changing the sheets also will not help much if dust is sitting on the bed frame and under the bed, since it moves onto the clean linen within days. Wipe the frame and the floor beneath it on the same day you change the bedding, and lift soiled sheets gently so you do not shake dust back into the room.
Wash earlier than planned when:
- someone has been ill, feverish or sweating heavily
- a dust event has blown through open windows
- a stale smell remains even after airing the room
- small children or pets have slept on the bed
