alarm reaction - flight or fight response to stress
resistance - continued exposure to stress leads to higher metabolic response to offset the stress
exhaustion - continued exposure to stress can negatively affect the body and lead to health problems
Hans made this discovery in the 1930s after studying the response of rats after the injection of hormones into them. He compared their cortisol and blood sugar levels in rats before and during the experiment.
He concluded that it was the stress that caused the rat to become ill and die
