Your bed may look clean, but it can collect sweat, body oils, dead skin cells, and allergens every night. Since you spend hours sleeping in your bedding, keeping it fresh is important for comfort and hygiene. The right washing routine depends on your habits, skin, and whether you share your bed with pets.

For most households, washing sheets once a week is a good balance between cleanliness and convenience. However, you may need to wash them every three to four days if you sweat heavily, sleep with pets, eat in bed, have allergies or asthma, experience eczema, or are recovering from an illness. Pillowcases should be washed every three to seven days, especially if you have oily skin or allergies.

Other bedding needs regular care, too. Wash blankets every two to four weeks, duvet covers every one to two weeks, and covered comforters every two to three months. Washable pillows generally need cleaning every four to six months, while mattress protectors should be washed every one to two months or sooner if spills occur. Always check the care labels before washing to avoid damaging the fabric.

You can also keep your bed fresher between laundry days with a few simple habits. Shower before going to sleep, remove makeup, avoid eating in bed, and allow your bedding to air out briefly each morning. These small steps can help reduce the buildup of oils, moisture, and dirt.

Finally, make sure your bedding is completely dry before putting it back on the bed. Damp sheets and blankets can develop unpleasant odors and encourage unwanted microbial growth. By following a consistent washing schedule and adjusting it to your needs, you can create a cleaner, more comfortable sleeping environment without spending every day doing laundry.
