Verified step by step guidance1
Understand the General Adaptation Syndrome (GAS), which describes the body's short-term and long-term reactions to stress in three main phases: Alarm, Resistance, and Exhaustion.
Identify the role of cortisol, a stress hormone released by the adrenal glands, which helps the body manage stress by increasing glucose availability and suppressing non-essential functions.
Recall that during the Alarm phase, the body initially reacts to stress with a 'fight or flight' response, involving adrenaline more than cortisol.
Recognize that the Resistance phase is when the body attempts to adapt to the ongoing stress, and cortisol secretion is most dominant to maintain prolonged alertness and energy.
Note that in the Exhaustion phase, the body's resources are depleted, and cortisol levels may drop, leading to decreased stress tolerance and potential health issues.
