Most people flush the toilet without a second thought. But recent scientific studies show that this common habit could be exposing you to harmful germs without you even realizing it.
1. What Is a Toilet Plume?
When you flush with the lid open, it doesn’t just remove waste — it also sends a burst of aerosolized particles into the air. This phenomenon is known as a toilet plume.
These tiny droplets can contain:
- Bacteria like E. coli
- Viruses
- Fecal particles and other pathogens
2. What Science Says (University of Colorado Study)
A team of researchers at the University of Colorado Boulder used lasers and high-speed cameras to capture what the human eye can’t see. The results were shocking: flushing with the lid open can launch particles up to 5 feet into the air, and they can remain suspended for minutes or longer.
These droplets can land on:
- Toothbrushes
- Towels
- Skin care products
- And anything else near your toilet
3. How to Prevent It
To prevent this invisible spread, the solution is surprisingly simple:
Close the lid before flushing. This single action significantly reduces the reach of toilet plumes and keeps your bathroom cleaner and safer.
Conclusion
Flushing with the lid open might seem harmless — but science says otherwise. For the sake of hygiene and your health, make lid-closing a daily habit.
