The term “fight or flight,” is often associated with circumstances under which adrenaline is released into the body.
The fight or flight response is a built-in mechanism dates back to our early ancestors allowing them to cope better with dangerous and unexpected situations.
With dilated blood vessels and air passages, the body can pass more blood to the muscles and increase oxygen in the lungs in a prompt manner, resulting in a boost in physical performance for short bursts of time.
For example, if we are attacked by a dog or involved in a severe auto accident.
We experience an energetic feeling that gives us the power and strength to either escape or attack. Because of this, an adrenaline rush can be intense and used to avoid danger or react quickly and even help rescue others.
