Close the toilet lid before flushing

If you use a flush toilet there is a simple habit you may want to follow close the lid before flushing.

Research from Flinders University in Australia found that flushing a toilet can send tiny particles into the air. Some of these particles may contain harmful germs.

Flushing can send particles into the air

When a toilet is flushed very small droplets and particles can become airborne.  They are too small to see but may remain in the air for more than 20 seconds.

Some particles can rise to a height where people may breathe them in.

What did the study find?

Researchers analyzed data from 22 previous studies that examined how toilet flushing releases particles and how these particles behave in the air.

The findings showed that flushing can spread tiny particles around the toilet area. Once airborne they may stay suspended for some time.

Why is this a concern?

If these particles contain germs they could potentially be inhaled or settle on nearby surfaces. However the actual health risk can depend on several factors and more research is needed to understand the impact.

Closing the lid may help

Researchers said closing the toilet lid before flushing can help reduce the spread of airborne particles.  Good ventilation in bathrooms may also help improve air circulation.

A simple hygiene habit

Closing the toilet lid before flushing is an easy precaution that may help limit the spread of tiny particles in the bathroom.

Keeping the bathroom well ventilated and cleaning surfaces regularly can also support better hygiene.
