Wearing underwear for two days in a row will not automatically cause a fungal infection, but it can increase skin irritation and discomfort.
Throughout the day, fabric absorbs sweat, natural oils, and dead skin cells, creating an environment that harbors bacteria and moisture.
Dampness from sweating or hot weather makes changing into clean, dry pairs even more important to avoid friction and maintain proper hygiene.
Opting for breathable fabrics like cotton alongside daily changes is a simple habit that protects skin and prevents unnecessary discomfort.
