Neat freaks obsessed with making their beds each morning could be courting tiny critters that cause asthma and allergies, according to new research. As many as 1.5 million house dust mites, which eat flakes of dead skin and cause respiratory problems in humans, can thrive in the warm, damp conditions of an occupied bed. But being too lazy to straighten the sheets every day can dry out bedclothes and lead to a dust mite massacre. “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,” said a researcher. Chalk one up for the slovenly.
