One of the most common mistakes when you go to the bathroom is to leave the toilet seat open when you flush.
According to what experts have revealed to Martha Stwear's website, the practice is unadvised for hygiene reasons. Understand why.
What happens when you flush?
According to what Bruce Hirsch, an infectious disease specialist, revealed when flushing, the mechanisms create a powerful vacuum.
“ This turbulence raises and spreads droplets and pieces of feces in a cloud of aerosol that reaches up to one and a half feet high (...) allowing bacteria to deposit on the walls of the bathroom, on the floor and on towels”.
Why is it always better to close the toilet seat
Pulling the toilet flush with the open toilet cover spreads an aerosol and microscopic swarms of enteric bacteria, including E. coli, Klebsiella, Salmonella and Shigella through the walls, sink, towels, magazines and toothbrushes.
“ They spread everywhere in the bathroom, ready to contaminate hands and faces with microbial gut waste,” says Hirsch.
Dissemination of the bacterium Clostridioides difficile is another risk. “It is the bacteria that causes suffering, sometimes explosive diarrhea and very strong odor, which causes a toxic colitis that makes the body sick,” he explains.
The expert advice is simple: always close the lid.
Tips for maintaining toilet hygiene
In spite of the previous recommendation, it should be noted that there is no need to disinfect the entire bathroom every time you flush the toilet. Yes, it should maintain regular cleaning, and it should be intensified every time someone gets sick.
Here are some of Hoang's healthier habits:
- Include the outside toilet in your cleaning routine: in addition to the inside of the toilet, it must disinfect the outside, both on the side and behind;
- Separate a cleaning cloth into the toilet: after cleaning the toilet, you should not use the same cloth for other surfaces;
- Always follow the time instructions: when disinfecting the surfaces, comply with the recommendations of the packaging for maximum efficacy;
- Always wash your hands: Rub your hands at least 20 seconds, including between your fingers and around your nails. Don't forget to dry them.
