What is adaptation syndrome model?

The adaptation syndrome model, proposed by Hans Selye in the 1930s, describes the body's physiological response to stress in three stages: alarm, resistance, and exhaustion. In the alarm phase, the body detects a stressor and initiates a fight-or-flight response. During the resistance phase, the body attempts to adapt to the stressor, maintaining a state of heightened alertness. If the stress persists and the body cannot adapt, it enters the exhaustion phase, leading to decreased function and potential health issues.
