Overview

• Experts advise washing bed sheets at least once a week in summer, doubling to twice weekly for those with night sweats, allergies or pets in bed.
• A minimum washing temperature of 40°C is recommended to kill bacteria and allergens that 30°C cycles may leave behind.
• Adding white vinegar or tea tree oil can boost antibacterial action during cooler washes.
• Air-drying sheets outdoors in direct sunlight is preferred for its natural disinfecting UV effect, with tumble drying reserved as a backup for delicates.
• Pillows should be laundered at least twice a year according to their filling to maintain overall sleep hygiene.
