I have had RA for two years now and I was in such pain at night that I couldn't sleep. My husband got me a ChiliPad because I was blasting the AC at night to try and cool down the room - and freezing him out in the process. The ChiliPad lets you set the temperature of your bed between 46 and 118 degrees. It's been a lifesaver, having some comfort at night and getting better rest helps a lot with the symptoms, and anytime I get a flare I can lie down in a cool place. You can get more info at **edit**
