If you’re fact-checking that claim, there isn’t one universal schedule for everyone. For most people, washing bed linens about once a week is a reasonable guideline.
A practical schedule
- Sheets and pillowcases: About once a week.
- Duvet covers: About every 1–2 weeks, depending on whether you use a top sheet.
- Blankets: Every few weeks or according to the manufacturer’s care instructions.
- Pillows: Wash or clean according to their care labels, often every few months.
- Mattress protector: Every 1–2 months, or sooner if soiled.
You may want to wash sheets more frequently if you sweat heavily at night, have allergies, sleep with pets, are ill, or have skin conditions.
Regular laundering helps remove sweat, skin oils, dead skin cells, dust, and allergens that accumulate in bedding. Always follow the care label for the appropriate washing and drying method.
