General Adaptation Syndrome (GAS): A three-stage model proposed by Hans Selye that describes how organisms respond to stressors over time. It includes stages of alarm, resistance, and exhaustion.
Cortisol: A hormone released during times of stress that helps regulate metabolism and suppress inflammation. It's like having a natural energy booster and anti-inflammatory agent in your body.
Stressor: Any event or situation that triggers the stress response. Stressors can be physical (e.g., injury) or psychological (e.g., exams), and they vary from person to person.
