Stress can be caused by both physiological and psychological stressors. The body responds to stress through the release of stress hormones and physical adaptations. Prolonged stress can lead to exhaustion. People respond psychologically to stress through feelings like depression, anxiety, and difficulty focusing. Personality traits like optimism can act as a buffer against stress while traits like anger and hostility increase health risks. Coping strategies like problem-focused approaches, social support, and relaxation techniques can help manage stress.

1. Stress and Its Management

3. Stress Definitions (continued) Distress —events or situations that produce negative or unwanted outcomes and are difficult to control Eustress —events or situations that create demands on a person that result in positive outcomes (e.g., becoming a new parent, accepting a desired job) Eustress can still have negative effects on the body and mind because it requires physical and psychological adjustments.

4. Response to Stress Each person appraises a situation according to previous experiences and personality. Some situations can have positive, neutral, or negative outcomes for different people.

5. Physiological Stressors Exercise Illness Injury Exposure to pollutants Exposure to extreme temperatures

6. Psychological Stressors Extreme emotions Difficult social situations Troublesome thoughts and relationships

7. Physical Responses to Stress Release of stress hormones Cortisol, epinephrine, and norepinephrine Release of endorphins Physical adaptations Increased heart and breathing rates, blood pressure, sweating, blood clotting ability, and size of pupils Decreased GI tract movements and saliva production

8. General Adaptation Syndrome Three-stage response to stress Alarm — adrenal glands release stress hormones Resistance — body maintains protective reactions and recovers normal status Exhaustion — occurs when stress persists; the body’s defense mechanisms weaken, leaving individuals more susceptible to infections

9. Psychological Responses Typically, stressed out people feel: Depressed and anxious Frustrated Irritable and angry The “stressed out” person may: Eat too much food Abuse substances Have difficulty focusing attention, making decisions, and sleeping

10. Psychoneuroimmunology A field of medical research that studies the relationships between the nervous and immune systems. Stress changes the normal balance and functioning of the immune system. Certain chronic health conditions are linked to stress and may worsen or recur during periods of increased stress (e.g., ulcers, headaches).

11. Personality, Disease, and Stress People who only see negative aspects of stressor may be more vulnerable to stress than those who make more positive appraisals of the situation. People who are less vulnerable to stress have personalities that act as buffers. - These individuals generally have more positive outlooks on life.

12. Personality, Disease, and Stress (continued) People who harbor feelings of anger, hostility, resentment, suspicion, and mistrust have a higher risk of cardiovascular disease than people who do not have these feelings. “Type A” persons are not necessarily at risk. Chronic stress increases the risk of cardiovascular disease, particularly stroke.

13. Personality, Disease, and Stress (continued) Stress responses can reduce effectiveness of immune system. Most scientific studies, however, do not show association between personality and cancer onset. Cancer patients with optimistic outlooks and fighting spirits tend to survive longer than cancer patients without these characteristics.

14. Coping Strategies Coping strategies are behavioral responses and thought processes that people use to deal actively with sources of stress. Problem-focused (e.g., planning, confronting, problem solving, time management, journal writing) Emotion-focused (e.g., use of defense mechanisms, humor) Social support (e.g., seeking assistance from friends, relative, support groups, spiritual help, pets)
