It turns out that simply throwing a dirty pair of knickers into the wash isn’t enough.
That’s because, according to The Good Housekeeping Institute, our underwear is actually a breeding ground for nasties like E. coli with 83 per cent of “clean” underwear containing up to 10,000 living bacteria.
It’s why washing them regularly just isn’t enough anymore. At least if you want to avoid contracting urinary tract infections and thrush.
It’s now recommended that underwear be replaced each and every year, no matter how well or how often you think you are washing them.
The Good Housekeeping Institute says that extra care should be taken when washing the underwear of a sick family member to avoid the spread of bacteria.

Pyjamas should be washed after three wears, or once a week as a woman, as our skin cells shed at a vast - and fast - rate.
