How often should you wash your bedding? A microbiologist explains

Washing bed linens regularly is crucial for health and sleep quality. We shed skin, sweat, and transfer microbes to bedding nightly, attracting dust mites and fungi. Sheets should be washed weekly in hot water, while mattresses need weekly vacuuming. Pillows, blankets, and duvets require cleaning every few months to remove allergens and irritants.
