How To Determine When To Wash Your Bed Sheets
October 1, 2025

How often do you believe it is fine not to wash bedsheets?
This is an aspect that you are likely to ignore, but it plays a big role in your hygiene, your sleep quality, and the way you feel out of your home. Your sheets may be fresh from the laundry, say you’re being your best grown-up self, and washing them weekly (or at least every other week).
Still, sweat, skin cells, dust, and allergens accumulate there not to mention whatever invisible floater of filth has come on in to sit for a spell, knowing that it doesn’t have an appointment until regular laundry day. Find out here when you should wash them, and why it matters to begin with clean ones.
How Often Should You Wash Bed Sheets?

I want to wash my bed sheets. How many times should I do it?
The general recommendation is: Wash your bed sheets every week. But you know what, life will have to deal with. For example:
If you sweat a lot at night, take a bath every night.
If you share beds with pets, be sure to wash your sheets more regularly, and they will still feel fresh.
You can’t expect to eliminate dust and pet allergens now, but you can consistently reduce them, Ms. Sheehan said. Wash bedding. The more frequently a person washes their sheets, pillowcases, and blankets, the fewer of their own skin cells they will have around for food for the bugs (dust mites are tiny spiders that thrive on shed human skin).
If you don’t sleep in the bed much (like, super infrequent guest room stints and the like), then 2 weeks should be adequate. The frequency at which you should be washing your bedding will depend purely on your own schedule.
Signs It's Time to Wash Your Bed Sheets
Even if you aren’t currently following a routine, your bed might be showing signs that it needs some extra care and attention. Here are key signs:
Smell: If your linen smells, there is nothing against it, but do they ask you to wash them?
Skin problems: Dirty beds may have breakouts or rashes.
Allergies: Were you more upset with a flowing nose or crowd sneezing in the last week? You may be sleeping with allergens building up in your bedding.
Visible dirt/stains: If you notice sweat, makeup, or pet hair on them, then they’re due for a wash.
Half-sleep: There’s sleep, sure — but there is also probably not all that clean.
Knowing these signs leaves you capable of doing your own laundry and maintaining some personal hygiene.
Conclusion
Maintaining clean bed sheets is essential not just for keeping them smelling fresh and clean, but also for taking care of your body, ensuring quality sleep, and maintaining a healthy sleep environment. “If it’s only when it’s blatantly overdue by then a small animal has declared your bed its own or you get an asthma attack in the middle of the night that you discover is because last winter’s colonies of dust mites are now having spring break then once-a-week change is O.K.,” Dr. Tierno said. So the next time you’ve vacuumed off the last of your mattress and are about to trudge through five years’ worth of drooped, food-stained mattress, let it double as a reality check: Do not be that person for whom the clean slate offered by a never-slept-in bed really counts as something.
