Are you guilty of not washing your pillows as regularly as you should? Yeah, us too.
However, a recent segment on daytime magazine show This Morning may have prompted you to stuff your pillows in the washing machine immediately.
Consumer expert Alice Beer joined presenter Holly Willoughby and Phillip Schofield to discuss the best tried and tested pillows - and imparted a rather grim nugget of knowledge with viewers.
"Nano is the sleep specialist and they have said that 41 per cent of people have never washed their pillow," she said.

"Can I tell you that 10 per cent of a two-year-old pillow, if you don't wash it, is made up of dust mites and their droppings."
The news did not sit well with Holly, who looked physically repulsed at the revelation.
"Oh God!" she said as she pulled a face. "That is so disgusting!"
Alice continued: "You have to wash your pillows. It is disgusting not to. Truly disgusting."

Viewers shared the sentiment.
"Omg I feel sick - 41 per cent of British people have never washed their pillows and will be full of dust mites etc!" one grossed out fan wrote on Twitter.
Another was completely lost for words, and just posted a vomiting emoji.
Dust mites eat flecks of human skin, and can cause allergies in some people.
However, they are fairly easy to remedy. Doctors advise using allergen-proof bed covers made of tightly woven fabric as they prevent dust mites from colonising or escaping from the mattress or pillows.

Washing bedding weekly, including sheets, blankets, pillowcases and bedcovers in hot water will kill dust mites and remove allergens.
Freezing non-washable items for 24 hours also can kill dust mites, but this won't remove the allergens.
Looks like we're going to have to do a major spring clean this weekend...
