Duvet Facts: You Won’t Sleep Tonight!


Wrapping up in a warm cosy duvet on a winters day can be heaven on Earth. Your own little cocoon filled with love and happiness. But you might not be the only snug bug in that cocoon.

We’ve got some gruesome facts that will change how you treat your duvet forever. You may want to take a shower after this one.

Before we start diving into the nitty gritty it’s super important to remember to buy a new duvet to be hygienic and sanitary. We spend a lot of time in bed so it only makes sense that it has great potential to be one of the dirtiest places in our homes.

Anyway, let’s begin..

1. Washable duvets should be cleaned in 40 degrees wash at least every 3 months for children and every 6 months for adults. This will lower the bacteria level by 55% and house dust mite level to 0.

2. If your duvet is not washed at least every 6 months, then they can contain up to 20,000 live dust mites. Now we can all agree we don’t want to be in a bed with them wriggling around.


3. We all sweat in bed and those sweat stains are great for bacteria to spread. These bacteria can even infect eczema lesions and possibly cause conjunctivitis.

4. Each week humans shed half an ounce of skin and a lot of that is in bed. Combine that with the warm moist environment that is your bed, and it makes a great place for those pesky dust mites. Pulling back your duvet and opening the window each morning can help release moisture and prevent dust mite breeding.

5. Remember I mentioned that you should get a new duvet every 5 years and clean it every 6 months? Well, the University of Worcester National Pollen and Aerobiology Research Unit did a study and discovered 70% of people had not washed their duvet in 10 years. 10 years! That’s got to make you shiver.


Indeed, your bed can potentially be a very unhygienic place but if you make sure to clean your duvets regularly and replace them every few years you shouldn’t have a problem. If it has been several years since your last duvet clean, then you know what to do.
