The scientist described GAS together the body’s way of adapting come a perceived threat to much better equip it to survive. A document on Selye’s GAS theory was released in The newspaper of Clinical Endocrinology in 1946.

The three stages the GAS

The 3 stages that GAS are:

alarm reactionresistanceexhaustion

What happens in ~ the body throughout each of these stages is discover below.

Alarm reaction stage

At the alert reaction stage, a distress signal is sent out to a component of the mind called the hypothalamus. The hypothalamus permits the relax of hormones called glucocorticoids.

Glucocorticoids cause the release of adrenaline and also cortisol, i m sorry is a tension hormone. The adrenaline gives a person a an increase of energy. Their heart rate increases and their blood pressure rises. Meanwhile, blood sugar levels also go up.

These physiological changes are governed by a component of a person’s autonomic nervous mechanism (ANS) referred to as the forgiveness branch.

The alarm reaction stage of the GAS prepares a person to respond to the stressor they space experiencing. This is often known as a “fight or flight” response.


During the resistance stage, the body tries to counteract the physiological transforms that happened during the alert reaction stage. The resistance phase is administer by a component of the ANS called the parasympathetic.

The parasympathetic branch the the ANS tries come return the human body to typical by reducing the quantity of cortisol produced. The heart rate and also blood pressure start to return to normal.
