So your mattress and your sheets are all wrong. Go get yourself a set of organic, or untreated cotton sheets (also called Green Cotton). Now your body will at least rest on something bit a cleaner. Eventually, you should consider pillows, comforters and a mattress systems that use no petro-chemicals. Replace foams and synthetics with wool, cotton or hemp. These natural fibers breathe better, and so do their owners.
