The body\u2019s response to perceived threats or danger. During this reaction, certain hormones, such as adrenaline (epinephrine) and cortisol, are released, speeding the heart rate, slowing digestion, shunting blood flow to major muscle groups, and changing various other autonomic nervous system (ANS) functions, giving the body a burst of energy and strength. This response is often present in panic attacks or anxiety.<\/p>\n
The first stage in the Stress Response, in which the body prepares to cope with a stressor. Physiological and psychological responses appear. It is a basic survival mechanism.<\/p>\n
A series of physical changes that prepare the body to react to stress.<\/p>\n
The activation of the sympathetic division of the autonomic nervous system is typically triggered by fear. This response involves the release of adrenaline (epinephrine), noradrenaline (norepinephrine), and other hormones from the adrenal glands and nervous system. As a result, the heart rate increases, pupils dilate, and blood flow to the muscles rises. These reactions make the body more efficient in either fighting or escaping from perceived threats. Prolonged or excessive fight-or-flight responses are associated with anxiety disorders.<\/p>\n
