10 Dysautonomia Symptoms
Reviewed: Dr. Mera
Symptom #6: Swings in body temperature
Body temperature is partly controlled by the autonomic nervous system. When we find ourselves in a hot environment, the ANS regulates the blood flow to our skin by changing the tone of the blood vessels that supply it so they can dilate and produce a cooling effect to lower body temperature. The opposite happens in a cold environment (vasoconstriction). Also, it regulates the excretion of sweat which also plays an important role in thermoregulation.
In patients that suffer from dysautonomias, the ability of the ANS to regulate body temperature can be compromised. Thus, patients with this condition can experience swings in body temperature: either increases or decreases in core temperature.
