I tried Prickles idea of using a heat lamp when I take a nap, I cover my eyes and sun bathe...extremely refreshing. I place the bulb ~3 feet (1m) away from my back. I rotate like a rotisserie chicken. My armpits sweat and smell real bad afterwards but I believe that its toxins coming 'cause I FEEL BETTER! Heat lamp bulb runs $4 at Walmart. There is a red glass model which is easier on the eyes for $8. 250W of infrared heat! Just make sure that the bulb is properly secured so it can't accidentally fall on you. I used a garage type clip on fixture and also secure the cord as a back up so NO accidents.
