People with dysautonomia cannot resist the changes in temperatures. Our limbs serve as the radiators. Along with the rest of the body parts, they make sure the person has a healthy temperature which is 37C. Through remodeling the blood flow to the extremities, our organism regulates the temperature. The autonomous nervous system is the one to manage any fluctuations in temperatures. The result of the disorder is the lower thermal control, which makes the patients suffer from the sudden heat or, vice versa, extreme cold.
