The fight-or-flight response in humans prepares the body to fight off or run away from

a potential threat. This response results from a series of nerve and chemical signals that

direct how cells function. This, in turn, determines the actions of organs in these situations.

Some of the changes experienced by the individuals as part of this response include:

increased pulse rate

increased blood glucose levels

increased breathing rate

Once the threat has passed, another series of changes returns the body to its original state. Why must

this occur?

Our hormonal levels, and the abnormal state itself in which our body finds itself in once we're experiencing stress, have to go back to baseline levels because if they didn't, very serious consequences would be suffered from people for whom this wouldn't happen. An elevated long-term stress response is considered to be very bad and an unwanted state to be in, as there are negative consequences associated with it (weight gain, weakened immune system, being two examples).
