How often should I wash my bed sheets?
The Weekly Standard
For most households, washing sheets once a week is the gold standard. This frequency helps remove dead skin cells, sweat, oils, and dust mites that accumulate over time. If you have allergies or asthma, weekly washing is especially important because dust mites can trigger symptoms.
If you sleep alone and shower before bed, you might be able to go up to two weeks, but weekly is still a good habit. In hot, humid climates or if you sweat heavily at night, wash more often—every 3–4 days.
- Weekly for most people.
- Every 3–4 days if you sweat a lot or have allergies.
- Every two weeks if you shower before bed and sleep alone.
Factors That Affect Frequency
Pets on the bed: If your dog or cat sleeps with you, wash sheets every 3–4 days to remove pet dander and hair. Illness: If you or your partner are sick, wash sheets daily to prevent spreading germs. Night sweats: If you experience night sweats, wash sheets every 2–3 days.
Also consider your bedding type: comforters and duvet covers can be washed less often—every 2–3 months—while pillowcases may need more frequent washing, especially if you have acne-prone skin.
- Pets: every 3–4 days.
- Illness: daily.
- Night sweats: every 2–3 days.
How to Wash Sheets
Always check the care label. Most cotton and linen sheets can be washed in hot water (up to 140°F) to kill dust mites, but high heat can shrink or fade some fabrics. For synthetic sheets, use warm water. Use a gentle, fragrance-free detergent if you have sensitive skin. Avoid overloading the machine so sheets get properly cleaned. Tumble dry on low or medium heat and remove promptly to reduce wrinkles.
Common mistakes
- Waiting too long between washes, allowing dust mites and bacteria to build up.
- Using too much detergent, which can leave residue that irritates skin.
- Washing sheets in hot water without checking care labels, causing shrinkage or damage.
