This might make difficult reading for some.
Because it turns out that even if you wash your underwear everyday, it's probably still dirty and you didn't even know it.
This is according to The Hygiene Doctor, Dr. Lisa Ackerley, who recently revealed the best practice when it comes to washing your undergarments, the Mirror reports.
The health expert explained that unless you set your washing machine to a certain temperature, it won't kill the bacteria on your pants - she added that because of this, you shouldn't put them in to wash with other household items.
Speaking to HuffPost, she said: "With knickers and pants, anything under 60 degrees won't kill the bacteria.
"Don't put the knickers in with the tea towels on a low wash, because you might have faecal contamination in your knickers and you wouldn't want that near your kitchen."
So all those times you washed your delicates at 30ºC or 40ºC, or shoved them in with the rest of your clothes, you weren't actually getting them very clean.
It's not a very pleasant thought, is it?
For those who aren't able to put their machine onto a higher setting for whatever reason, don't panic, you can still help your undies be faeces-free.
Instead of turning up the heat settings, Dr Ackerley suggests adding a laundry sanitiser to the wash load to remove germs.
These can be purchased from your local supermarket for about £3.
