A recent study conducted by scientists at the University of Arizona has finally answered the age-old question of whether it is better to keep the toilet lid up or down when flushing. The findings of this study could potentially revolutionize our bathroom habits.

The researchers set out to investigate whether closing the toilet lid before flushing could reduce cross-contamination in the bathroom. They discovered that the toilet is a breeding ground for airborne bacteria and viral particles, known as toilet plumes, which are microscopic particles that are released into the air during flushing.

While it has been widely believed that closing the toilet lid can help mitigate the spread of these contaminants, the study revealed that there is no evidence to support this claim. However, the researchers did uncover an interesting finding – the addition of a disinfectant, such as a toilet bowl cleaner or a Rim Block, to the toilet bowl before flushing can significantly reduce cross-contamination.

Another study conducted by the University of Colorado Boulder used a bright green laser to illuminate the air above the toilet bowl during flushing, revealing the extent of pathogen dispersion. The results demonstrated the alarming potential for the spread of dangerous bacteria and viruses, such as E. coli and norovirus, through toilet plumes.

These findings shed light on the importance of maintaining proper hygiene practices in the bathroom and the potential health risks associated with toilet plumes. It is evident that further research and awareness are needed to address this concerning issue and ensure the safety of bathroom users.
