FLUSH WITH THE LID DOWN TO SAVE TEETH

Dr Charles Gerba, a microbiologist from the University of Arizona, warns that you should always flush the lavatory with the seat lid down.
If you don’t, a polluted plume of bacteria and water vapour erupts out of the loo. The polluted water particles float for a few hours around your bathroom before they all land, some on your toothbrush.

Dr Gerba says: ‘Droplets containing bacteria or viruses are ejected from the bowl when flushed and settle throughout the bathroom.

‘It doesn’t happen all the time, but E.coli and other faecal based bacteria really can make you ill, so unless you want to brush your teeth with what was in the toilet, it’s a good idea to close the lid.’


Microbiologist Dr Anthony Hilton, the head of biology and biomedical science at Aston University in Birmingham, says: ‘I’ve been involved with studies where we’ve put ultra-violet dye down the toilet.

‘After flushing, it’s possible to detect it all over the bathroom. And if you do keep the lid up, common sense would suggest it’s probably not the best idea to keep toothbrushes next to the toilet.’
