    • 3.1: What Is a Stressor?

      Most of us feel stressed from time to time. Of course, the degree of stress we experience depends on our ability to cope with unwelcome or unexpected events or stressors. This tension affects our minds and bodies.

      You have probably heard of the fight or flight response to stress. Walter Cannon (1871–1945), an American physiologist, was among the first to explore stress and how our bodies respond to stressful events. He described the "fight or flight response" to stress, which suggests our body quickly arouses the sympathetic nervous system and the endocrine system when confronted with a stressful event so that our pupils dilate, our breathing quickens, we begin to sweat, our heart rate increases, and our muscles tense or tremble. These physiological responses prepare us to fight or escape from stressful events.

      This coping mechanism helps us protect ourselves from perceived or real threats (stressors). Examples include the fear of public speaking, phobias (such as spiders, snakes, bridges, and water), and fear of a lack of control in a given situation. Of course, some stress level is a healthy sign of realistic awareness. We may have to meet a physical or mental challenge that immediately demands our knowledge, ability, or experience. These same stressors that prompt us to run to safety motivate athletes to perform their best when facing competitors. Let's examine the causes of stress and ways to reduce unhealthy stress.
