Do you routinely line public toilet seats with toilet paper before sitting down?
This habit offers little protection. Toilet seats are designed so bacteria can't survive long on their smooth surfaces. Other spots—like flush valves or walls—often harbor far more germs. Flushing aerosolizes bacteria onto walls and even toilet paper rolls, where they persist longer than on seats.
No cause for alarm
Public restrooms may seem grimy, but the risk of infection from seat contact is extremely low, according to hygiene research. Prioritize thorough handwashing afterward—your hands unwittingly touch your face and mouth, the true transmission route. Even then, your immune system neutralizes most bacteria harmlessly.
