A hygiene expert asserts that changing bed linens weekly is not medically necessary. The expert states that health risks are minimal even after two months without a change. Proper drying of bedding is far more critical than striving for complete sterility. The focus should be on ensuring adequate ventilation to prevent moisture build-up, which fosters bacterial growth. Complete elimination of germs is unrealistic and not the primary goal of bed hygiene. This challenges common household routines and suggests a shift in perspective on cleanliness standards. Ultimately, prioritizing thorough drying over frequent washing can maintain a healthy sleeping environment.
