These “invisible roommates” might be living in your duvet cover.
Our bed sheets, duvet covers, and pillowcases can easily become a breeding ground for various microorganisms over long-term use. While we sleep, our bodies naturally shed skin flakes and secrete sweat and oils. These substances provide a rich source of nourishment for the “uninvited guests” of the microscopic world.
- Bacteria: Common staphylococci and streptococci found on the skin surface, as well as certain bacilli present in the environment, can attach to bedding through body contact or by settling from the air. Under suitable temperature and humidity conditions, they can reproduce rapidly. Studies have shown that after just one week of use, the bacterial load on bedding may already have reached a considerable level.
- Fungi: Moisture-loving fungi such as Trichophyton rubrum and Candida albicans may also be present. This is especially true for individuals with athlete’s foot; if proper care is not taken, these fungi can contaminate the bedsheets through contact and may even indirectly affect other parts of the body.
- Dust mites: These tiny creatures, almost invisible to the naked eye, feed mainly on the dead skin flakes shed by the human body. Beds are their ideal habitat. Dust mites themselves, as well as their droppings, are common and potent allergens.
- Viruses: When someone has a respiratory infection or certain viral skin infections, viruses may also contaminate bedding through droplets or direct contact. Although their survival time outside the body is relatively limited, there is still a risk of indirect transmission.
How Often to Wash Bedding and Duvet Covers for a Cleaner, Healthier ![]()
Sleep
To ensure a hygienic sleep environment, it is recommended to establish a reasonable bedding washing schedule based on the season and the specific needs of different groups of people
General recommendations:
- Summer (or during hot, sweaty seasons): It is recommended to wash bed sheets and pillowcases once a week. The duvet cover can be washed every two weeks.
- Winter: Bed sheets and pillowcases are recommended to be washed every two weeks. The duvet cover can be washed once a month.
Key groups:
- Infants and young children, elderly people, pregnant women, and individuals with weaker immune systems: It is recommended to wash the bedding once a week.
- Patients with allergic conditions (such as asthma, allergic rhinitis, or eczema) or other skin diseases: It is advisable to shorten the interval to once every 3 to 5 days.
- Households with pets: It is recommended to wash the bedding once a week.
How should you wash duvet covers, bed sheets, or pillowcases?
- Water temperature: Washing with hot water at 55–65°C can effectively kill most dust mites and bacteria. For bloodstains and other protein-based stains, it is recommended to soak and pre-treat them in cold water first to avoid high temperatures setting the stains and making them harder to remove.
- Detergent: It is recommended to use a neutral laundry detergent and avoid products that are too strongly alkaline, as they may damage the fabric fibers and reduce cleaning effectiveness.
- Thorough drying: After washing, it is best to dry the bedding in direct sunlight during peak daylight hours (such as from 11 a.m. to 3 p.m.), making use of ultraviolet rays for additional disinfection. Avoid drying in damp, shaded conditions for long periods to prevent mold growth.
