The fight or flight response refers to a specific biochemical reaction that both humans and animals experience during intense stress or fear.

During this reaction, certain hormones like adrenalin and cortisol are released, speeding the heart rate, slowing digestion, shunting blood flow to major muscle groups, and changing various other autonomic nervous functions, giving the body a burst of energy and strength. Originally named for its ability to enable us to physically fight or run away when faced with danger, its now activated in situations where neither response is appropriate, like in traffic or during a stressful day at work.

The fight or flight response, also known as the acute stress response, refers to a psychological reaction that occurs in the presence of something that is terrifying, either mentally or physically. The fight or flight response was first described in the 1. American physiologist Walter Cannon. Cannon realised that a chain of rapidly occurring reactions inside the body help mobilise the bodys resources to deal with threatening circumstances. In response to acute stress, the bodys sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulates the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline. This results in an increase in heart rate, blood pressure and breathing rate. After the threat is gone, it takes between 2. The fight or flight response is also known as the acute stress response.

Besides getting ready to run and fight, the body is preparing to think quickly and be aware of threats by hearing, seeing and smelling things better. Pulling blood away from the skin also helps decrease bleeding from cuts and scrapes. Sweating Running or wrestling with bears will certainly cause an increase in body heat.
