Flushing a toilet sends aerosolized droplets into the air, possibly carrying harmful bacteria like E. coli and Staphylococcus aureus. A study in China examined two types of toilets—squat and bidet—and found that flushing a toilet with human waste increases airborne bacteria concentrations significantly. Enhancing bathroom ventilation can reduce these risks. The researchers highlighted the health implications of bioaerosol exposure in public restrooms and recommended optimizing ventilation systems to lower contact with harmful bacteria.
Flushing a toilet releases harmful bacteria into the air, increasing the risk of stomach bugs and respiratory infections, especially if the seat isn't down.
Researchers found significant reductions in airborne bacteria after flushing an empty toilet compared to one with human waste, highlighting health risks.
