The Nature and Mechanics of Stress

Stress is a universal human experience, often described as a feeling of being overwhelmed or under pressure. In biological terms, stress is the body’s response to any demand or threat. When an individual perceives a challenge, the body undergoes a complex series of physiological changes designed to enhance performance and ensure survival. While contemporary society often views stress as a purely negative phenomenon, it is fundamentally an evolutionary adaptation. Understanding stress requires an exploration of its physiological mechanisms, the distinction between its various forms, and the long term impact it has on physical and mental health.
