After being confronted by a dangerous dog, heart begins to race and beat strongly, pupils dilate, and hairs stand up, are not the result of increased levels of epinephrine in the blood. Those signs are the result of the fight-or-flight response.

What is the fight-or-flight response?

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. The parasympathetic nervous system acts like a brake.

During the fight-or-flight response, our blood flow is being redirected so we might experience feeling cool or like our hands and feet are cold and clammy. Our face might also appear flushed as blood and hormones circulate throughout our body. Blunt pain response is compromised.
