Fight-or-flight response: This term refers to the body's physiological reaction to a perceived threat or stressor. It prepares the body for action by increasing heart rate, releasing adrenaline, and boosting energy levels.
Cortisol:This hormone is released by the adrenal glands in response to stress. It helps regulate blood pressure, suppresses the immune system temporarily, and increases glucose levels for energy.
General Adaptation Syndrome (GAS):GAS is a three-stage model that describes the body's response to stressors: alarm (initial shock), resistance (adaptation phase), and exhaustion (prolonged exposure leading to depletion of resources).
