But the body doesn't always cooperate. When triggered by a stressful event, it automatically prepares a chemical arsenal. And without an outlet, this automatic ammunition can turn back on itself, wreaking havoc on emotional and physical health. Just about any life change is a stressor. Even the anticipation of a lifestyle change, such as an award or a vacation, can cause stress.
Some stressors are negative, provoking anger, sadness, worry or fear.
The death of a loved one, loss of job, divorce, or an argument with a friend are all negative stressors. Other stressors are positive, evoking joy, elation or excitement. Marriage, pregnancy, job promotion and school graduation are examples of positive stressors. Researchers have developed a Social Readjustment Scale to evaluate common stressors in North American society. At 100 stress points, death of a spouse is the highest source of stress on the scale.
