If You Can't Remember the Last Time You Changed Your Sheets, Read This

There's nothing quite like collapsing into bed at the end of a long day. Pulling up the covers, sinking into soft pillows and finally letting go of everything that's been weighing on you can feel like pure relief. But that cozy, restful feeling only really hits when your bedding is clean. If it's been a while since you washed your sheets, that sense of calm might be hiding more than you realize.
Sheets collect a lot over time. That includes sweat, dead skin cells, body oils and dust mites. Pillowcases can get even dirtier, holding onto makeup residue, hair products and facial creams. That buildup can affect your skin and your sleep quality. Experts generally recommend washing all your bedding at least once a week to keep things fresh and healthy. If you are unsure how to get started or want to make your laundry routine more effective, here are six simple tips to help you clean your sheets the right way.
How often should I change or wash my sheets?
The common rule of thumb is to wash sheets every other week. Ideally, sleep experts recommend changing sheets every week but agree that every two weeks is the absolute longest one should go sleeping on the same set of sheets.
When to wash all bedding Bedding type Frequency Sheets Once a week or every other week Pillowcases Once a week or every other week Duvet covers Once a week or every other week Comforters Once a month or every other month (or more frequently if you sleep with pets) Duvet inserts Once or twice a year Mattress pads Every three to four months
Why do we wash our sheets and bedding?
Hygiene is always important, even with our bedding. If you can't see stains or smell any odor, it doesn't mean your sheets are clean. Sheets can accumulate dead skin, mites, animal dander, pollen, makeup, bodily secretions and more grime, which may cause discomfort or skin rashes.
One of the biggest reasons to regularly clean sheets is because of sweat. In a May study, 41% of participants reported experiencing night sweats in a month, and generally, people tend to run hot when covered in blankets or living in warmer climates. Sweat can soak into the sheets which can clog up the fibers and make the sheets smell.

You have allergies or asthma
You have sensitive skin
You sweat or overheat frequently
You sleep naked
You sleep with a pet
You eat in bed
You get in bed before showering
You lay in bed wearing clothes you wore out in public
You have an infection or open wound that touches the bedding
What's the best way to machine-wash my sheets?
Most bedsheets are machine-washable and aren't much of a hassle to clean. Cotton and linen bedsheets are especially easy, while silk and satin are a bit more temperamental, requiring cold temperatures and slow spin cycles. It's best to always check the care tag on your sheets but this is the best method to machine-wash the majority of sheet sets:
1. Don't overwhelm the machine
It can be tempting to just throw every pillowcase, fitted sheet and comforter right into the machine but throwing everything in at once may be too much and you may not get a good clean. I recommend washing the fitted and flat sheets together with your pillowcases and then washing any heavier comforter, quilt or throw blanket separately.
Definitely don't throw in any clothing or towels with your bedding because it could leach color or have buttons and zippers that will damage delicate sheets.
Bulkier items like duvet covers should be washed alone.

2. Check the label
I always recommend checking the care label for the ideal washing temperature because some fabrics can shrink in the wash. It's best to use the hottest temperature the sheets can tolerate because hot water most effectively kills germs and bacteria. Colder cycles may not fully get rid of the grime.
Polyester blends are best in warm water, while cotton can tolerate hot water. Silk and satin sheets should be washed on a cold, gentle cycle.
3. Separate by color
Separate your sheets by color to preserve the colors and prevent dye from transferring. This means that you should make sure to put light-colored and dark-colored sheets together before washing.
4. Check bedsheets for stains
Stains are better when cared for pre-wash, so take a few minutes to examine your sheets or pillowcases for stubborn blemishes. You can use a gentle dish soap and water, or baking soda and water mixture to let sit for a few minutes if you spot a dark mark or makeup stain.
5. Measure out detergent
Less is usually more when using detergent. Too much detergent can lead to the machine using excess water or cause buildup in the washing machine's pipes. Most detergents are acceptable to use on cotton and linen sheets but choose a detergent for delicate fabrics to wash silk and satin sheets. There are many silk or satin-friendly detergents on the market.
A good rule of thumb is to use 2 ounces (1/4 cup) or half a cap full of liquid laundry detergent for a regular-sized load of bedding. You can also use 4 ounces (1/2 cup) or 1 full cap of liquid laundry detergent for a larger load of bulkier items.
I also recommend skipping the fabric softener because it can weaken the fabric.
6. Dry completely
For most sheets, you can use the dryer on low to medium heat. Satin and silk sheets would do best to air dry because they can be easily damaged even on a low-heat dryer cycle.
You can also throw in a few dryer balls with your bedding because they allow gaps, helping the bulkier sheets to dry more quickly and evenly (I always hate when I think I'm finally ready to make my bed and I realize one whole section is still damp from being bundled up).
You can avoid cleaning your bedsheets as often by making it a habit to not eat in bed, not sleeping with your pet and only cuddling down in the sheets after a shower. It may seem like a hassle to strip your bed every week but it's well worth the extra effort, so you can sleep and relax a little easier.

Can you wash sheets and clothes together?
While you can wash sheets and clothes together, many experts recommend washing them separately to prevent clothes from getting caught in the sheets and not being washed thoroughly. Sheets may also have different washing instructions from clothes so washing them separately can help preserve the different fabrics and prevent damage.
