If you'd describe your sleep lately as "crappy," you have no idea how correct you are in your word choice. That's because, on average, ten percent of the weight of a two-year-old pillow is attributable to dust mites and their droppings.

Yes, that's right, ladies and gentlemen, we're sleeping on crap. And, it's not just on our pillows that mites seem to enjoy so much; mattresses are veritable party clubs for dust mites, gathering anywhere from 100,000 to 10 million of these tiny suckers inside. What is it these intrepid invaders want from us? Our dead skin. You're feeling itchy right now just thinking about it, aren't you?

Because dust mites are responsible for many cases of asthma, eczema, and many allergy problems, it's a good idea to either replace your old bed and pillow or wash them thoroughly with hot water as often as you can.
