Galvanic Skin Reflex

The skin reflex is a reaction of the body for protection, which consists of an involuntary change in the condition of the skin and hair when irritated. This defensive reaction was called by scientists the skin-plaztonic reflex; it is facilitated by skin heat exchange and a feeling of moisture, as well as tension in the facial muscles. The reaction is expressed as a general dilation of blood vessels, mainly on the face and upper extremities, itching of the skin, headache and lethargy, and sometimes muscle weakness. If in this situation you increase the impact on the secretion point, the degree of the reaction will increase; the reaction will proceed similarly if you suddenly start pressing on the active points
