How Often Should You Wash Your Bedding?

Ever wondered how often you should be washing your bedding? Most people wash their bedding far less often than they should. Your sheets, pillowcases, and duvet collect dead skin cells, sweat, oils, and dust mites every single night. 

If you care about clean, fresh bed sheets, here's exactly how often you should be washing every piece.

Key Takeaways

• Sheets and pillowcases should be washed every 1 to 2 weeks. Once a week is ideal.

• Duvet covers need washing every 2 to 4 weeks.

• Duvets and comforters can be washed every 2 to 3 months.

• Pillows should be washed every 3 to 6 months.

• Mattress protectors need washing every 1 to 2 months.

• Blankets and throws should be washed every 2 to 4 weeks depending on use.

• If you have pets, allergies, or sweat a lot, wash everything more frequently.

How Often Should You Wash Each Bedding Piece?

Sheets and Pillowcases: Every 1 to 2 Weeks

This is the most important one. Medical experts recommend washing your sheets at least once a week. 

Sweat, body oils, dead skin cells, and everything else your skin picks up during the day ends up on your sheets every night. That builds up fast, especially on pillowcases, which are in direct contact with your face for hours every night.

If you sweat a lot while you sleep, have oily skin, or are getting over an illness, wash your sheets more frequently, not less.

Duvet Covers: Every 2 to 4 Weeks

Your duvet cover acts as a barrier for your duvet, so it doesn't need washing as often as your sheets. But it still picks up oils and sweat from your body, so don't let it go longer than a month between washes.

If you sleep without a top sheet and your duvet cover is in direct contact with your skin every night, treat it like a sheet and wash it weekly. Quality duvet covers are designed to be washed regularly, so don't hold back.

Duvets and Comforters: Every 2 to 3 Months

Your duvet itself doesn't need washing as often because the cover protects it. Every 2 to 3 months is the standard recommendation.

Always check the care label before washing. Most duvets can go in a large-capacity washing machine at home, but some require professional cleaning.

Pillows: Every 3 to 6 Months

Pillows absorb sweat, oils, and saliva over time. Even with a pillowcase on, they need washing every 3 - 6 months. If your pillow smells off or has yellowed, wash it sooner.

Most synthetic and down alternative pillows can be machine washed. Memory foam usually can't, so check the label first.

Mattress Protectors: Every 1 to 2 Months

Your mattress protector catches everything that gets through your sheets. It's doing a lot of work. Once a month is a good target, and it's one of the easiest things to add to your regular laundry routine.

Blankets and Throws: Every 2 to 4 Weeks

If you use a blanket on top of your duvet, wash it every 2 to 4 weeks. If it's more of a decorative throw that doesn't touch your skin much, once a month is fine. Most bed linen including throws and blankets is machine washable, making it easy to keep everything fresh.

Quick Reference: Washing Frequency Guide

When You Should Wash More Often

The guidelines above work for average use. These situations call for more frequent washing:

If you have pets in the bed. Pet dander, hair, and dirt all end up on your sheets. Wash them at least once a week, ideally twice.

If you have allergies or asthma. Dust mites thrive in bedding. Weekly washing in hot water at least 130°F kills dust mites and reduces allergens significantly.

If you sweat a lot. Night sweats mean your sheets get saturated faster. Don't wait two weeks.

If you eat in bed. Crumbs attract bacteria and insects. Wash your sheets after any food spills.

If you're sick. Wash your bedding as soon as you start feeling better to clear out any bacteria or viruses in the fabric.

If you have acne-prone skin. Pillowcases in particular should be changed every few days if you're dealing with breakouts.

What Happens If You Don't Wash Your Bedding Often Enough?

Dust mites build up quickly. These microscopic creatures feed on dead skin cells and thrive in warm, humid environments like your bed. They're one of the most common triggers for allergies and asthma, and you can't see or feel them until symptoms start.

Bacteria and fungi can grow in unwashed bedding, especially in warm, damp conditions. This can irritate your skin and contribute to breakouts or rashes over time.

Your sleep quality suffers too. Fresh, clean bedding just feels better, and that comfort affects how well you actually sleep.

Tips to Make Your Life Easier

Have two sets of sheets. When you strip the bed, put the clean set straight on. No waiting for laundry to dry before you can sleep. If you're not sure which bed sheet material washes best and lasts longest, that's worth knowing before you buy your second set.

Wash on a schedule. Pick one day a week for bedding laundry and stick to it. Once it's a habit you don't have to think about it.

Use the right temperature. Hot water at 130°F or above kills dust mites and bacteria. Check your fabric's care label first, as some materials need a cooler wash.

Dry thoroughly. Damp bedding put back on the bed before it's fully dry develops mildew quickly. Make sure everything is completely dry first.
