Dermatologists explain how often to change bed sheets, towels, and pajamas

Dermatologists recommend changing bed sheets weekly to prevent the buildup of sweat, oils, dead skin cells, and allergens. This practice is considered the cleanest and most skin-friendly routine, though some may extend it to every one to two weeks depending on personal factors like sweating and allergies. Towels should be changed after three to four uses, and pajamas once or twice a week, with proper drying being crucial for hygiene.
