Also one major thing overlooked is your mattress. Unless you've made the effort to buy an all cotton or natural rubber mattress, you're sleeping on pure synthetics.

Consider the lenght of time the synthetics are entering your system through your pores while you're sleeping.
(I actually remember having slept on a synthetic/cotton blend futon and getting night sweats.)

Look online. You can get a 100 % natural latex rubber topper (2") for under 200.00
