How Often Should You Wash Your Sheets?
Wash sheets about once a week for everyday use, and more often for pets, sweat, allergies, illness, hot weather, or heavy skin and hair product transfer.
Wash sheets about once a week for a bed used nightly. Wash more often when pets sleep in the bed, someone sweats heavily, allergies or asthma are flaring, the weather is hot, someone is sick, or the sheets smell or feel oily. Guest beds can go longer while unused, but wash after every guest stay.
Sheet washing schedule
Everyday bed
About once a week
Balances hygiene, skin oils, sweat, and normal fabric wear
Pets in bed
Every few days to weekly
Fur, dander, soil, and outdoor debris build up faster
Heavy sweating or hot weather
More often than weekly
Moisture and odor develop faster
Allergies or asthma
Weekly or more often
Bedding can hold dust mites, pollen, and dander
Guest room
After each guest stay
A clean reset matters more than calendar frequency
Care labels still matter
The wash frequency is not the wash method. Cotton, linen, bamboo, silk, flannel, and specialty sheets can need different water temperatures, detergents, and dryer settings. Use the care label before assuming hot water or high heat is safe.
Simple weekly sheet routine
- 1Strip sheets and pillowcases from the bed on the same day each week.
- 2Check the care label before choosing water temperature and dryer heat.
- 3Pretreat makeup, sweat, body oil, or pet stains before washing.
- 4Dry fully before folding or remaking the bed.
- 5Keep a spare sheet set so weekly washing does not depend on finishing laundry the same day.
FAQ
Is every two weeks too long for washing sheets?
For a low-use bed, two weeks may be workable, but weekly is the better default for a bed used every night. Wash sooner for sweat, pets, illness, allergies, skin irritation, or hot weather.
Should pillowcases be washed as often as sheets?
Yes, and sometimes more often. Pillowcases collect face oils, hair products, sweat, and allergens, so weekly is the baseline and every few days can make sense for acne, allergies, or heavy sweating.
How often should guest room sheets be washed?
Wash guest sheets after each guest stay. If the room sits unused after clean sheets are put on, refresh them before guests arrive when they have collected dust or stale odors.
