The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
Is fight or flight sympathetic or parasympathetic?

Which branch of the autonomic nervous system is responsible for fight or flight?
sympathetic nervous system (SNS): One of the three parts of the autonomic nervous system, along with the enteric and parasympathetic systems. Its general action is to mobilize the body’s nervous system fight-or-flight response; it is also constantly active at a basal level to maintain homeostasis.
What are the 3 stages of fight or flight?

What is the difference between the parasympathetic nervous system and the sympathetic nervous system?
What is the major difference between parasympathetic and sympathetic nervous system?

The sympathetic nervous system, on the other hand, prepares the body for fight and flight response.

Studieshave shown that a deep sigh returns the autonomic nervous system from an over-activated sympathetic state to a more balanced parasympathetic state.
