A Toilet Flush Can Launch Microscopic Particles Toward Your Face — and It Could Impact Your Health
Learn more about the particles a toilet flush can launch into the bathroom and how those particles could impact the health of adults and children.
When you flush a public toilet, powerful turbulence can spray microscopic particles into the air, potentially carrying disease-causing microbes. Researchers at Flinders University in Australia analyzed studies examining how high volumes of flushing affect the distribution and concentration of these aerosols.Researchers found that higher concentrations of aerosols were linked to both larger amounts of material in the toilet bowl and stronger flushes.
These airborne particles can linger in the breathing zone of an adult for over 20 seconds, and in some cases, were detected at distances up to 59 inches (150 centimeters) away and heights of 64 inches (163 centimeters) above the floor. This puts people, especially young children, at risk of inhaling the particles.While closing the toilet lid before flushing could help reduce inhalation exposure, the researchers note that it does not completely prevent aerosols from escaping.
They recommend regularly cleaning the toilet, ensuring proper ventilation, and selecting models with lower flush volumes to minimize the spread of potentially harmful microbes.
