A recent study has proven that, at any given time, there are an average of 1.5 million microscopic insects called dust mites living between your sheets. These tiny, beetle-like creatures feed off human skin cells and require a warm, damp atmosphere to survive and thrive.
When we sleep, we sweat. A lot. Rumour has it, the average person may sweat up to a litre of fluid per night. This creates an ideal breeding ground for the mites, who will begin to hump like Hugh Hefner and deliver their creepy, eight-legged offspring.
