Sympathetic arousal (i.e., activation of the sympathetic nervous system) is associated with the so-called fight-or-flight response, as the body anticipates and prepares for action, either mental or physical (Hanoch and Vitouch, 2004, Poh et al., 2010).
What is sympathetic release?
When a subject is heated, the stimulation of temperature-sensitive nerve endings in the skin, and the raising of the central body temperature, results in the reflex release of sympathetic vasoconstrictor tone in the skin of the extremities, causing a measurable temperature increase at the site of release.
What causes sympathetic overactivity?
The sympathetic nervous system becomes overactive in a number of diseases, according to a review in the journal Autonomic Neuroscience (opens in new tab). These include cardiovascular diseases like ischemic heart disease, chronic heart failure and hypertension.

What is sympathetic response?
The sympathetic nervous system connects the internal organs to the brain by spinal nerves. When stimulated, these nerves prepare the organism for stress by increasing the heart rate, increasing blood flow to the muscles, and decreasing blood flow to the skin.

- Splash cold water on your face.
- Take a cold shower.
- An ice pack against your face and middle of your forehead.
What are some sympathetic responses?
Physiological changes induced by the sympathetic nervous system include accelerating the heart rate, widening bronchial passages, decreasing motility of the large intestine, dilating the pupils, and causing perspiration.
What are sympathetic symptoms?

- Increase heart rate.
- Dilation of the pupils.
- Secretion of sweat glands.
