How often should I wash my sheets? Now we are getting personal. So let’s talk about your sheets. When was the last time you changed them? I wouldn’t be surprised if you don’t remember. Are you in the group of washing your sheets ‘every week’ or ‘when I feel like it’? Whichever group you fall into, let’s see what the research tells us about how often should you wash your sheets and what does it mean for bed hygiene.
I know a guy that changes his sheets every 3 days. When I researched the question “How often should I wash my sheets?” I realized there was a world of difference between “should” and “need to” wash your sheets.
How Often Should I Change My Bed Sheets?
The answer is probably not enough.
In informal polls, only about ⅓ of us are changing our sheets every week or every other week. Once a month changers make up another ⅓. The rest change when they feel like it.
Here are some shocking findings from a survey run in the UK
- Males aged 18-25 were the grubbiest, changing their sheets once every 3 months. How gross! When any 18-25 male ever asks you the question “How often should I wash my sheets?” or “How can I attract women?”, be sure to tell them that changing sheets once every 3 months is unhygienic. And, smelly sheets are a total turn-off for the opposite sex!
- The group that washed their sheets weekly were mostly aged 35-50 and mostly women.
- On average the men interviewed in the survey only owned one sheet set whereas the women owned 3, on average.
- Couples change their sheets every 2 weeks, on average.
How Do Sheets Get Grimey?
Skin oil and shed skin is the short answer.
Each night we shed ten of thousands of skin cells onto our sheets. As much as one-fifth of an ounce of skin residue can accumulate on sheets in just one week. This becomes food for microscopic critters like dust mites. So when you ask yourself, “How often should I change my bed sheets?”, doesn’t that fact alone, move you to change them. Washing your sheets removes those dead skin cells from the food supply for dust mites.
If you don’t shower right before bedtime, you might also bring dirt onto your sheets or pollen in your hair. If you share your bed with your dog or cat, animal dander is left on your sheets and if they have been mixing with dirt…well you get the picture.
What Happens If You Don’t Wash Your Sheets?
If you don’t wash your sheets, bacteria will build up and you may have a swarm of bed bugs as unwelcome bed partners! In the long term, both of these are bad for your health.
As your shed skin cells build up over time, they create a great habitat for dust mites. They thrive on those skin cells as food. Dust mites can create allergic reactions, rhinitis, and asthma. I can verify this. Being an asthmatic, I have a horrible allergy to dust mites. I sneeze and wheeze and need to take Ventolin. And when I wake up in the morning, my eyes are itchy and bloodshot. Needless to say, I wash our sheets weekly!

So I’ve addressed the answer to “How often should I wash my sheets” but what about your mattress cover, pillows etc?
You can wash your pillows. That’s recommended to be done at least twice a year. Check the care tag on the pillow because different pillows have different requirements.
For a general guideline, you can wash the pillow in cold water and dry it in the dryer on low heat. Also, replace your pillow at least every 18 months. Don’t skimp on your pillow. It cradles your head while you sleep and can make you wake up happy or with a pain in your neck.
If you have acne, change your pillowcases every 3 or 4 days. Otherwise once a week is a good idea. Our faces have more oils than our bodies. And if we put our face on old oil, it could aggravate your skin to break out more often.
Most people wash the mattress pad when they wash their sheets.
If your mattress has a removable cover, also wash it with your sheets.
You should wash comforters when they start to smell musty or at least twice a year. If you let pets up on your bed, you may want to wash them more often as the pets bring in dirt and pollen.
If you have very large comforters and duvets, you may want to find a laundromat and use the large capacity machines.
And wash throw blankets a few times a year according to care tag directions.
And when you’re sick
Finally, wash everything after you’ve been sick.

Hospital staff need to change beds quickly. So we can learn some important tips from them.
- Move the covers down off the bottom of the bed. Then move the pillows to the middle of the bed.

- About the midpoint, you can then take the pillows out of the pillowcases and move the pillows onto the mattress at the head of the bed. Leave the pillowcases on the sheets and continue rolling it down.
- Then take a clean fitted sheet and hook one corner on the bottom of the mattress. Stretch it over to the other corner and hook that in. Then you can pull one side up. (OK, you are going to have to move the pillows at this point onto the sheets. Just try and keep them off the floor.)
