Bedding harbours dust mites, skin cells and sweat over time, making regular washing a genuine hygiene matter, not just a preference.
General guidance
Weekly washing is the standard recommendation for most households, keeping dust mite populations and allergen buildup in check.
Factors that mean more frequent washing
Allergies, pets sleeping on the bed, or hot weather causing more sweat all point toward washing more often than the weekly default.
Pillow and duvet care
Pillows and duvets need less frequent washing than sheets, but still benefit from periodic attention, every few months is reasonable.
