How Often Should You Change Your Sheets? More Often Than You Probably Think

Few things feel quite as good as climbing into a bed with freshly changed sheets. The funny thing is, your old sheets may not have looked or even felt dirty. Yet the minute you slide between fresh ones, you can tell the difference. Maybe it’s the clean scent, the cool, smooth fabric or simply that unmistakable feeling of freshness. And that difference hints at something we don’t always notice: sheets gradually pick up a lot often without looking obviously dirty.

So, how often should you actually strip the bed? Probably more often than many of us do.

The Status

In a 2011 Bedroom Poll, the National Sleep Foundation surveyed 1,500 U.S. adults and found that 62% changed their sheets weekly or more often and another 29% did so every other week. In other words, 91% said they changed them at least every two weeks.

More recent surveys suggest that fresh sheets are still firmly tied to the idea of a clean home. In a 2025 American Cleaning Institute survey of 1,000 nationally representative U.S. adults, 40% named washing sheets as one of the hygiene practices they prioritized to stay healthy. Among those planning to spring clean, 67% planned to tackle bed linens or their mattress.

But knowing you ought to wash them and actually getting around to it are two different things. In a separate 2026 American Cleaning Institute survey, nearly one in three Americans said they would be embarrassed to admit how long it had been since they last washed their sheets.

That may sound familiar. Sheets rarely come with an obvious “wash me now” signal, so it can be easy to keep stretching laundry day — especially if they still look and smell fine.

“Individuals with disorders that may result in excess sweating or who are confined to bed should consider washing or switching sets of sheets more frequently.”

Dr. Desmond Shipp, a dermatologist at the Ohio State University Wexner Medical Center.

The Ideal Frequency

There isn’t one official rule that fits every sleeper, but most guidance lands somewhere between once a week and once every two weeks.

The American Cleaning Institute, a trade group for cleaning-product manufacturers, recommends changing bedsheets about every two weeks, and more frequently if you sweat at night.

Medical guidance tends to lean a little more frequently, recommending changing sheets at least once a week. For a simple routine, think “weekly” for anything that regularly touches your body — your fitted sheet, top sheet, pillowcases and a duvet cover if you sleep directly under it.

Dr. Matt Hershcovitch, an ENT specialist and founder of SoCal Breathe Free Sinus & Allergy Centers, said weekly washing is sufficient for most people, but those with sensitive skin, pets in the bed or allergies — especially dust-mite allergies — may benefit from more frequent changes.

“Changing the pillow cases even more frequently is helpful due to the head and face contact,” Hershcovitch said.

The rest of the bed doesn’t necessarily need the same weekly treatment. Blankets and bedspreads that don’t touch your skin directly can generally be washed about monthly, while washable pillows, comforters and similar inserts may only need laundering every few months.

Check the care label, since some fillings and fabrics don’t tolerate frequent washing. And don’t let the calendar overrule common sense. If your sheets are damp, visibly dirty or contaminated with body fluids, change them even if laundry day was yesterday.

You may also want to change them more often if you:

• sweat heavily or have night sweats
• live in a hot or humid climate
• sleep with pets
• sleep naked
• have asthma or allergies
• have eczema or another skin condition
• are recovering from an illness
• have a weakened immune system

Older age alone doesn’t mean you need a different laundry schedule.

If you’re healthy and mobile, the same weekly routine works just fine. But the situation changes if you spend much of the day in bed, have incontinence, a wound or fragile skin. Wet or soiled sheets should be changed right away, and some people may need fresh linens daily or even more often.

“Individuals with disorders that may result in excess sweating or who are confined to bed should consider washing or switching sets of sheets more frequently,” said Dr. Desmond Shipp, a dermatologist at the Ohio State University Wexner Medical Center.

Why Regular Changes Matter

Your bed may look clean, but every night you leave a little bit of yourself behind.

Sheets and pillowcases collect dead skin cells, sweat, body oils, saliva, dust and residue from skincare and hair products. Over time, that buildup can lead to odors, irritation and a more welcoming environment for dust mites, especially when bedding stays warm and damp.

Dust mites feed largely on flakes of skin and thrive in warm, humid surroundings. They don’t bite, but their waste and body fragments can trigger sneezing, congestion and asthma symptoms in sensitive people. So if allergies have you waking up stuffier or itchier than usual, your bedding may be one place to look.

 Research showed that allergens removed from bedding by washing typically reappear within about a month, reinforcing why a strict weekly cycle — rather than an occasional deep clean —  is the effective intervention for allergy sufferers.

Zippered allergen-resistant mattress and pillow covers can also help, but they don’t replace washing your sheets. “Use mattress covers that prevent dust mites. And keep bedroom humidity under 50% and run a HEPA filter home air purifier,” Hershcovitch advised.

Clean, dry bedding matters even more with age, as skin becomes thinner, drier and easier to injure. For people who spend a lot of time in bed, keeping sheets dry, smooth and wrinkle-free can help reduce friction against fragile skin.

Choose with the Sleeper in Mind

If you’ve ever wondered whether 1,000-thread-count sheets must be better than 250-thread-count ones, don’t get too hung up on the number. Fiber, weave, breathability, washability and feel matter, too.

If you sleep hot, breathable cotton or cotton percale can feel cooler and lighter. If you prefer a smoother feel, cotton sateen may be more comfortable, though it can sleep warmer.

“Moisture-wicking fabrics also help remove bacteria, dead skin and dust mites. Fabrics that dry readily can also be useful because dust mites thrive in humid environments,” Hershcovitch said. For dry or sensitive skin, soft fabrics and fragrance-free detergent may help reduce irritation.

For frail older adults or those who spend more time in bed, prioritize smooth, lightweight, easy-to-wash bedding. Lighter layers are easier to change and may be safer to handle than one bulky comforter.

There’s another practical consideration that’s easy to overlook: changing the bed itself can be work. If pulling a fitted sheet over a heavy mattress means climbing, overreaching or wrestling with bulky bedding, choose lighter pieces or ask for help. Clean sheets aren’t worth a fall or a strained back.

A Fresh Start, Once a Week

For most people, changing the sheets about once a week is a simple, workable target. Think of the calendar as a reminder, not a deadline: if the sheets get sweaty, damp or dirty sooner, swap them sooner.

If changing the bed feels like a chore, at least it’s one with a reward waiting at the end: that fresh-sheet feeling when you climb into bed.
