It has been mentioned many times before that leaving the toilet lid open while flushing is harmful. Scientists have demonstrated how dangerous this can be for human health, with a bright green laser and high-resolution camera recording.Researchers from the University of Colorado Boulder say these invisible splashes contain microscopic particles of urine and feces. The published video revealed that water droplets gushed into the air at a speed of 2 meters per second and rose to a height of about 1.5 meters.
It invites the spread of disease
The largest droplets tend to settle on surfaces within seconds, while smaller particles can remain suspended in the air for minutes or longer. These particles, which can carry pathogens such as coli, C. difficile, noroviruses and adenoviruses, are very dangerous for human health.
The situation in public restrooms is even more risky. Because even ten flushes is not enough to clean the toilet from the aerosol particles left behind by previous visitors. As a result, it should be a habit to keep the toilet seat closed while flushing the toilet.
The scientists hope that sanitary ware manufacturers will take this research into account and consider how to improve the design of toilets, while public health professionals will consider developing disinfection and ventilation strategies for public restrooms.
