If you value your health, it's time to stop being neat. At least when it comes to making your bed in the morning.

Researchers at Kingston University have found out that bed bugs, those things that literally make your skin crawl, can't survive in the warm and dry conditions that are found in an unmade bed. Around 1.5 million house dust mites are believed to reside in the average bed, surviving on flakes of human skin and producing allergens which are inhaled while we sleep.

Researcher Dr Stephen Pretlove told the BBC:

We know that mites can only survive by taking in water from the atmosphere using small glands on the outside of their body. Something as simple as leaving a bed unmade during the day can remove moisture from the sheets and mattress so the mites will dehydrate and eventually die.

The experts recommend leaving your bed unmade for the day while you're out and only making it when you're ready to get back in. That's obviously not going to go down well with the tidier people out there but if they're that bothered by it they can bang out the hoover and go full Monica on the bed before they make it.
