Did you know that flushing the toilet with the seat up can send bacteria-laden water droplets up to a metre away? Many of us rush and skip closing the lid, but experts say it’s an important step that helps keep your bathroom cleaner and healthier.
- Flushing toilets release water droplets called 'toilet plumes' up to a metre high.
- These plumes can spread harmful gut bacteria and viruses onto nearby surfaces.
- Closing the lid before flushing dramatically reduces germ spread.
What happened
Research and expert insight reveal that flushing a toilet with the seat up causes a fine spray of water droplets, sometimes called the 'toilet plume,' to spread as far as a metre around the bowl. This plume carries bacteria and viruses originating from faecal matter, making surfaces like the toilet floor, seat, and nearby items potentially contaminated with harmful microbes.
Importantly, this risk persists regardless of whether the toilet was used for urination or defecation; the water plume can carry germs left behind from previous users. Microbiologist Primrose Freestone highlights that these droplets can settle on objects in the bathroom, including toothbrush holders close to the toilet, where they may linger, especially on moist surfaces.
Why it feels good
Understanding the science of toilet plumes can empower you to maintain a more hygienic bathroom environment with minimal effort. Simply closing the toilet lid before flushing significantly curtails the spray of bacteria-filled droplets, reducing the chance of germs landing on surfaces you frequently touch.
This small but effective change can provide peace of mind, knowing you’re lowering your family’s exposure to common gut infections and viruses like norovirus. While our immune systems are strong, it’s comforting to know you’re taking a simple step to help protect yourself and loved ones.
What to enjoy or watch next
Try making it a habit to always close the toilet seat before flushing to keep your bathroom fresher and safer. It can also be helpful to reconsider where you place items like toothbrush holders—keeping them covered and at least two metres from the toilet to avoid contamination from any stray splashes.
For anyone interested in bathroom hygiene, there are great resources and videos online showing how these invisible plumes spread germs and tips for keeping your space clean. Embracing these small changes makes your home healthier with very little effort.
