On average, people spend 6-8 hours sleeping each night. During that time, your bed sheets collect dirt, sweat, oils, and dead skin. This buildup of dirt and grime can eventually lead to allergies, acne, dust mites, and even a decrease in your health.

To stay healthy, and keep your bed sheets free of allergens and dust mites, you should regularly clean your bed sheets. This will not only improve your hygiene, but it will also help you sleep better. This guide will walk you through the why and how of washing your sheets.

How Often to Wash Your Sheets

We recommend you wash your sheets at least once a week. If you have pets who sleep on the bed with you, you sleep without clothes, or if you share the bed with someone else, you might want to wash your sheets two times a week.

Cleaning your sheets frequently is also important if you suffer from allergies. Even a small amount of dust or dander can trigger allergies, and regular cleaning, especially of your mattress and sheets, can limit allergens in your home.

It also helps to have an extra set or two of sheets to swap out while washing the current set. This will make sure your bed is protected from potential spills or dirt, and you won’t have to worry about remaking your bed right before you go to sleep.

Why Is It Important to Wash Your Sheets Regularly?

Washing your sheets regularly will help you maintain better hygiene and keep you healthy. It will also prevent the buildup of a number of things you don’t want on your bed or on you:

  • Dead skin
  • Dirt
  • Allergens
  • Body oils
  • Dust mites
  • Pet dander

Because you spend a large amount of time in bed night after night, these things can build up quickly and cause a variety of problems. Allergies, acne, skin irritation, and eczema are just a few of the negative side effects dirty bed sheets can cause.

How to Wash Bed Sheets

Now that you know how often you should wash your sheets, it’s also important to know HOW to wash your sheets. Depending on the type of sheets you have (i.e. silk versus cotton) will determine how you go about washing your sheets. We recommend always checking the manufacturer tag before washing to make sure you clean them properly.

Here are other important steps to follow while washing your bed sheets:

  • Read the manufacturer tag for cleaning instructions.
  • Pre-treat stains, like blood or urine stains, with the proper cleaning solutions and methods.
  • Always wash sheets on a gentle cycle to prevent any tearing or fraying.
  • Wash your sheets with cold water, because cold water is better at removing stains.
  • Dry sheets on a low heat setting to prevent shrinking.

How Often to Wash Other Bedding

Now that you are comfortable washing your sheets, the rest of your bedding is just as important. Your pillow and pillowcase, as well as your comforter and any blankets, can collect dust and grime, too. Cleaning them regularly will help you stay healthy and sleep better.

Here are a few tips for washing bedding other than bed sheets:

We recommend cleaning your pillows every three to four months. You will wash your pillow differently depending on the type you own. We always recommend vacuuming your pillow with the upholstery attachment on your vacuum first. Spot treat second. Then wash it in the washing machine or by hand and let air dry or place it in your dryer. Be sure to check the pillow's manufacturer or tag for washing instructions.


Wash your pillowcases as often as you would your bed sheets. If your pillowcases come with your set of bed sheets, follow the same instructions you would with your bed sheets, as well. Otherwise, always check the manufacturer tag before cleaning.

We recommend washing your duvet once a week to once a month. You will wash your duvet differently depending on the fill inside. Again, we recommend reading over the manufacturer tag to prevent ruining it during cleaning.

If your bed stays fairly clean, you only have to wash your comforter three to four times per year. You can, however, follow a similar once-a-month schedule like a duvet cover. The important thing is to make sure your bed stays clean year-round, so you stay healthy year-round. Make sure to check the manufacturer tag on your comforter, because some comforters can only be dry cleaned.

Mattress Protector

Mattress protectors should be cleaned as regularly as your bed sheets. It will help keep your mattress cleaner longer but should be washed often to prevent any buildup of dust or dander. Make sure to check the manufacturer tag for proper cleaning instructions so that your mattress protector will last a long time.


Don’t forget about your mattress! Your mattress should be cleaned regularly, too; at least every six months. Not all mattresses are created equal, though, so make sure to read your mattress tag for proper cleaning and care.
