Experts generally recommend washing bed sheets once a week to maintain hygiene and cleanliness. This frequency helps remove skin flakes, bodily oils, sweat, dust mites, and pet hair that accumulate on sheets
. Washing weekly is widely supported by multiple expert sources and books on laundry and cleaning
. However, washing every two weeks can be acceptable for some people, especially if they do not sweat much, do not have allergies, or sleep alone without pets
. People with allergies, pets, or who sweat heavily should wash sheets more frequently, ideally weekly
. Pillowcases often need more frequent washing than sheets, sometimes every few days, since they come into direct contact with the face
. Mattress and pillow protectors should also be washed periodically, but less often than sheets
. In summary:
- Ideal frequency: Once a week for most people
- Acceptable for some: Every two weeks if conditions are mild (no pets, low sweat, no allergies)
- More frequent washing: If you sweat a lot, have allergies, pets, or skin conditions
- Pillowcases: Change more often, about every few days
- Mattress protectors: Wash less frequently, every few months or as needed
Washing sheets in cold or warm water is usually sufficient, with hot water reserved for tough stains, allergies, or illness-related disinfection
. This routine helps keep bedding fresh, hygienic, and comfortable, contributing to better sleep quality and skin health
