Document Summary

Stress and stressors have both immediate and cumulative effects that can influence health. Stress: physical and psychological response to internal or external stressors. Chronic stressors have been shown to be linked to environments through environmental psychology. Sources of stress : major life events, catastrophic events, and chronic hassles, some of which can be traced to a particular environment. Stressors challenge you to do something about it having lack of control over the situation can add to the stress. Studies show that perceived control over stressful events can be related to more effective coping. Physiological reaction to stress reactions: hpa axis (walter cannon) Stress can produce changes in every system of the body and mind, stimulating both physical reactions and psychological reactions: fight-or-flight response: emotional and physiological reaction to an emergency that increases readiness for action. In selye"s theory, resistance to stress builds over time, but then can only last so long before exhaustion sets in.
