The Biological Roots of the Stress Response
Most people think of stress as a modern nuisance, but it is actually a deeply rooted biological program designed for survival. In the field of psychology, stress is defined as the body's physical and mental reaction to a perceived threat or challenge. While it originally served to keep humans safe from physical danger, it now manifests more frequently in response to school, work, and social pressures. Understanding the psychology of stress is essential for managing its effects on our health and our communities. Because stress is so common, it has become one of the most significant social issues in the modern world.
The psychology of stress begins with a physical process in the brain known as the "fight or flight" response. When we encounter a difficult situation, the brain triggers the release of hormones like adrenaline and cortisol. These chemicals increase the heart rate, speed up breathing, and sharpen focus to prepare the body for action. In prehistoric times, this helped humans escape predators or defend their homes. Today, however, the brain often reacts the same way to a difficult exam or a public speech. Because the body cannot easily distinguish between a physical threat and a mental one, many people live in a constant state of high alert.
