It's disgusting: Scientists reveal the mistake we all make near the toilet

A scientific review of 22 studies reveals that flushing the toilet produces a hidden cloud of tiny droplets that rise to breathing height for about 20 seconds. The spray can spread bacteria and viruses into the room and onto surrounding surfaces. Researchers explain why even lowering the lid is not completely safe, and warn of the significant risk in hospitals and nursing homes.

A comprehensive scientific review published in the journal 'Science of the Total Environment' analyzed 22 studies and found that flushing a toilet generates a powerful vortex that emits a cloud of microscopic droplets at breathing height. The droplets remain airborne for about 20 seconds and can spread bacteria and viruses to nearby surfaces, including toothbrushes and handles. Researcher Lira Adiani from Flinders University in Australia explained that the fact that the particles were detected at breathing height indicates a real pathway for inhalation exposure. A direct link was found between the concentration of microorganisms in the toilet and the amount of particles released, as well as between water pressure and the extent of dispersion. Closing the lid does not completely prevent dispersion, but directs the droplets sideways and downward instead of vertically. Researchers recommend regular disinfection and closing the lid as risk mitigation measures, emphasizing that the real threat is in hospitals and nursing homes for those with compromised immune systems.
