General Adaptation Syndrome
by Dr. Hans Selye
Alarm phase – The theory concurs that the body naturally reacts to stress by activating its fight or flight response system.

by Dr. Herbert Benson
The response is defined as your personal ability to encourage your body to release chemicals and brain signals that make your muscles and organs slow down and increase blood flow to the brain.
