Signs It’s Time to Replace Your Everyday Cotton Underwear
Signs it is time to replace your everyday cotton underwear include stretched elastic, thinning fabric, persistent stains, and a fit that rolls or bunches.

Cotton is a natural fiber. It breaks down faster than synthetic materials like polyester or nylon. Each wash and dry cycle causes tiny fibers to snap and weaken.
Important: Heat from washing machines and dryers accelerates fiber breakdown. Cotton loses about 10% of its tensile strength after 50 washes, according to textile engineering studies.
