Household germs can get into your bed sheets through direct contact with contaminated surfaces, such as unwashed hands or clothing. For example, bacteria like Staphylococcus aureus, commonly found on skin, can transfer to sheets and potentially cause skin infections like cellulitis.
Dust and bacteria thrive in warm environments such as your bed and bedding, so unwashed bedsheets can contribute to existing health or skin problems. Pneumonia: pneumonia is a type of chest infection than can make breathing more difficult. Bedsheets can host a range of bacteria including Strep. Pneumoniae.
Bacteria and Germs: Bed sheets can harbor bacteria, viruses, and fungi from sweat, saliva, skin cells, and other bodily fluids. If sheets are not washed regularly, these microorganisms can proliferate, potentially leading to infections or illness.
'The typical adult sheds 1.5 grams of dry skin a day, and with a large amount of time spent in bed, a high amount is found in the bedsheets. These skin flakes attract dust mites, one of the most common causes of asthma and allergies,' explains sleep expert April Mayer from Amerisleep.
There's a possibility of re-infection, as the germs and bacteria lingering on the bed sheets and pillowcases can remain active for a significant duration. Allergens can accumulate, potentially leading to asthma attacks or allergy symptoms, further complicating the recovery process.
Your bed may host bacteria
Take Staphylococcus aureus, which is fairly contagious and can cause skin infections, pneumonia and worsen acne. Not only have S. aureus been found to live on pillowcases, research also shows that some strains are resistant to antibiotics.
Without regular cleaning, dirty sheets can contribute to allergies, skin breakouts, asthma, and more. For your health and sleep quality, it's important to keep things clean – but how often should you wash your sheets?
Ackerley says that the dust mites increase a person's risk of getting a cold or suffering from allergies. But that's not all; our bed sheets can also harbor bacteria that causes the flu or food poisoning. She calls this "Sick Bed Syndrome," and told the Daily Mail that most people don't realize it's happening to them.
Sickly Sheets
Most bacteria or viruses can survive on soft surfaces for minutes to hours. The duration varies based on the specific microbe. For example, flu viruses live on tissues for just 15 minutes, but some stomach bugs can survive on fabrics for 4 hours.
The presence of dust mites in your home (especially the bedding where you sleep) can make symptoms of allergies and asthma much worse. Constant exposure to these contaminants could even lead to allergic rhinitis, a condition that can cause severe sneezing, congestion or severe asthma attacks.
In 2018, scientists at the University of Ibadan in Nigeria found E. coli in unwashed hospital bed clothes, along with other pathogenic bacteria known to cause urinary tract infections, pneumonia, diarrhoea, meningitis and sepsis. Unclean linen represents a real infection risk in such settings.
How often should you wash your bed sheets if you're sick? If you or a member of your family is ill, then experts recommend that bedding is changed every day if possible or at least that your pillowcase is cleaned daily as germs and viruses can live for several hours and even survive a wash.
With the wrong bed sheets, sensitive individuals can find themselves awake in the wee-hours --coughing, itching, sneezing and wheezing. According to the College of Allergy, Asthma, and Immunology, dust-mites and bacteria are the primary offenders.
Failure to wash bedsheets regularly can leave skin exposed to dirt, sebum, cosmetic products, and debris which will not only cause dust mites to accumulate, but can result in outbreaks of conditions such as acne, rashes, as well as cause irritation and itching, and flare-ups or eczema.”
Over time, mattresses can become a breeding ground for dust mites, mold, and bacteria, potentially causing health issues like allergies, skin irritations, and respiratory problems.
The more your laundry piles up, the more it becomes a breeding ground for pathogens. These pathogens can survive for weeks in a pile, and this is a health risk to your family. Besides, laundry can transmit feces, blood, skin, and saliva-borne pathogens.
Viruses like influenza, the coronavirus and RSV can cause a fever, Jone said. "Fever is a sign that the body is fighting these viruses, and patients will have chills related to the fever. Staying warm will reduce the discomfort of the chills and help circulate blood to carry the immune cells to their destination."
"If you don't wash your bedsheets enough, your dead skin cells are going to build up in these sheets." Sound horrible? It gets worse. That build-up means small creatures known as mites can feed off those cells, causing discomfort and skin rashes.
“Not washing your sheets can cause 'sick bed syndrome'. “A warm bed containing dust mites, shed skin, other body debris, and faecal contamination, provide a welcome environment for bacteria and viruses to grow and reproduce.”
The bedroom is home to a slew of allergens including dust mites, pet dander, chemicals, dust, and molds.

Dirty sheets don't cause scabies because the disease isn't related to hygiene or cleanliness. But scabies can spread from person to person through bedsheets. If you have a rash and it's so itchy you can't sleep, make sure you contact your healthcare provider.
You may be thinking, can you get bed bugs from not washing your sheets? No—bed bugs have absolutely nothing to do with cleanliness levels. However, washing your sheets regularly gives you the opportunity to look for and remove any possible bed bug infestations.
Generally speaking, it's recommended to wash your hair once it's greasy or unclean to the touch. For some people, that means washing every other day. For others, it could mean shampooing once a week. You may be familiar with the idea that washing your hair less often will “train” it to be less oily.
