Thermal energy is primarily dissipated as infrared light which moves at the speed of light. There is no way for space to accumulate heat. If that were the case the entire solar system would be unlivable. The IR emitted by satellites is truly negligible in comparison to the electromagnetic radiation emitted by the sun.
Fix? No.
Focusing on ways to reduce neck and jaw tension has helped reduce the severity and hence disruptive force of mine though. Using a mouth guard at night helps my jaw tension and switching to a buckwheat pillow and posture improvements has helped my neck tension. Neck tension also frequently accumulates if I sit hunched forward and let my shoulders pull forward. Laying on my back on yoga mat with a small towel rolled up into a cylinder and lined up with my spine can help correct some of that. I will also sometimes run a pair of rubber lacrosse/massage balls up and down either side of my spine. I set them in place under me and scoot up down to roll them along my spine using my own weight to exert pressure. It hurts like crazy but releases tension more reliably than any stretch ever can.
