Think Flushing Is Harmless? It Could Create a Microbe Cloud
What Happened
A review of 22 studies found that flushing a toilet can release tiny airborne droplets containing microbes, with some particles reaching adult breathing height and remaining in the air for at least 20 seconds. Researchers say the phenomenon is real, though the actual infection risk remains unclear.
Key Takeaways
Closing the lid before flushing may help reduce exposure, but does not completely stop aerosols from escaping. The concern is greatest in busy public bathrooms and healthcare settings.
