In the alarm reaction stage, stress stimulates the body to send messages to the hypothalamus to the glands, which stimulates the sympathetic nervous system. Sympathetic nerve fibers charge up the vital signs at any hint of danger to prepare the body's defensesófight, flight, or freeze. The adrenal glands release adrenaline (epinephrine), which causes the body to take in more oxygen, dilate the pupils, and increase arterial pressure and heart rate while constricting the peripheral vessels and shunting blood from the gastrointestinal and reproductive systems and increasing glycogenolysis to release free glucose for the heart, muscles, and central nervous system. When the danger has passed, parasympathetic nerve fibers reverse this process and return the body to normal operating conditions until the next sign of threat reactivates the sympathetic nervous system. During the resistance stage of the generalized anxiety syndrome, if the threat has ended, the parasympathetic nervous system is stimulated and the body responses relax. If the threat persists, the body will eventually enter the exhaustion stage when the body stores are depleted as a result of the continual arousal of the physiologic responses and little reserve capacity.
