Experts say this is where your sleep and health can be at risk.

How often should bed sheets be washed and changed?
According to experts, duvet covers, pillowcases and bed sheets should be washed at least every two weeks, using the hottest temperature listed on the bedding care instructions to effectively remove germs.

If you have allergies, infections, sleep naked, or don’t shower, wash your sheets more often. For pillows, wash them in hot water every three months to kill bacteria.

If you want to skip this, note that studies have shown that one-third of your pillow’s weight can be made up of “dead skin, dust mites, and bugs” — which can be prevented with regular washing.

Blankets should be washed at least twice a year because dead skin cells and bacteria can build up on them. This should be done more often if you tend to sweat a lot, spill coffee or food on your blanket, share your bed with pets, or if you have allergies.

Finally, depending on the individual situation and condition, mattresses, bedding, and pillows should always be cleaned regularly to ensure sleep and health for yourself and your family.
