Peripheral temperature is a useful measure for the evaluation of sympathetic/parasympathetic activity. A non-invasive tool that allows evaluating the peripheral temperature of a patient without contact with the skin is the infrared thermal image (iTF). Various negative affective states (pain, anxiety, depression, anger, alexithymia, social isolation) increase sympathetic activity (decreasing peripheral temperature) and thereby increase pro-inflammatory cytokines, such as interleukin 6 (IL-6) which has been linked to affective alterations; while relaxation promotes parasympathetic activity (increasing peripheral temperature). We present the bio psychosocial evaluation of six patients with different concentrations of IL-6 with diagnoses of chronic non communicable diseases, their iTF pre-post psycho physiological intervention in relaxation and their psychological profile for affective diagnosis. Patients with a higher level of peripheral temperature (hands, nose) or ability to increase it, showed a psychosocial profile without emotional disturbances. In contrast, the patients with the highest level of IL-6 concentration showed the lowest peripheral temperature in the hands and did not manage to increase it after the relaxation strategy. The iTF allows assessing the autonomic activity associated with various affective states. If the patient increases his peripheral temperature after relaxation, he has a better clinical prognosis than the patient who does not.
