If making your bed has always been a constant struggle, or the fight between you and your significant other, this news might just have you throwing that duvet to the floor. In fact, making your bed has now been proven to be harmful to your health. So how are the manners your mammy insisted on affecting your health? Apparently, there are on average 1.5 million microscopic dust mites living between your sheets, which feed off your skin cells. As researchers soon learned, we sweat a lot when we sleep, with the average person losing up to a litre of fluid per night. Requiring a warm, damp atmosphere to grow and multiply, the sweat and body heat from your bedsheets are just the right breeding ground to give these mites the chance to reproduce again, and again and again… Dr. Stephen Pretlove from Kingston University School of Architecture explains, “We know that mites can only survive by taking in water from the atmosphere ing 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.” Never making your bed won’t kill off all of those dust mites, but if you suffer from allergies, the airing of your sheets should help kill off some of those pesky insects. So now you don’t need to feel guilty that you never manage to tuck that duvet in every morning…
