How often should you wash your pillow? The answer may surprise you

Pillows accumulate sweat, oils, and allergens, necessitating cleaning every three to six months, or more frequently for those with specific sensitivities. While pillowcases should be washed weekly, the pillow's filling dictates the cleaning method. Regular washing and proper drying are crucial, but pillows eventually wear out and should be replaced every one to two years to ensure hygiene and support.
