Temperature Sensitivity in Fibromyalgia & Chronic Fatigue Syndrome

When you’re exposed to heat, does it feel like you’re burning up? Does it seem impossible for you to cool off? Or maybe it’s cold that bothers you, chilling you to the bone, leaving you unable to warm up.

Or are you one of those people with fibromyalgia (FMS) and chronic fatigue syndrome (ME/CFS) who is cold all the time, or hot all the time, or alternately hot or cold while out of sync with the environment?

 If any of those scenarios sounds familiar to you, you may have a symptom called temperature sensitivity.We don’t yet know exactly what causes this symptom, but we do have some compelling research. Much of it suggests abnormalities in the autonomic nervous system, which deals with homeostasis and our bodies’ reactions to environmental changes, including the “fight or flight” reaction.

With that established, researchers are now able to look deeper into that system to figure out what exactly is going wrong, and they’re finding some interesting things.
