14. Slide 14 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Stress and Illness Walter Cannon observed that, in response to stress, the sympathetic nervous system activates the secretion of stress hormones, triggers increased heart rate and respiration, diverts blood to skeletal muscles, and releases sugar and fat from the body’s stores, all to prepare the body for either “fight or flight.”

17. Slide 17 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Stress and Illness In addition to this first (and faster) track (fight or flight), the cerebral cortex operates on a slower track by stimulating the hypothalamus and the pituitary gland to trigger the release of glucocorticoid stress hormones, such as cortisol, from the outer part of the adrenals.

19. Slide 19 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Understanding Stress: Effects of Stress (Continued) Stress and the HPA Axis: Prolonged elevation of cortisol is related to: –increased depression, memory problems, etc. –impaired immune system, which leaves the body vulnerable to disease. 19

22. Slide 22 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Stress and Illness In addition to this first (and faster) track (fight or flight), the cerebral cortex operates on a slower track by stimulating the hypothalamus and the pituitary gland to trigger the release of glucocorticoid stress hormones, such as cortisol, from the outer part of the adrenals.

23. Slide 23 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Stress In Hans Selye’s general adaptation syndrome (GAS), the body’s adaptive response to stress is composed of three stages. In Phase 1, we experience an alarm reaction due to the sudden activation of our sympathetic nervous system. Heart rate increases and blood is diverted to the skeletal muscles.

24. Slide 24 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Figure 14.4 Selye’s general adaptation syndrome Myers: Psychology, Eighth Edition Copyright © 2007 by Worth Publishers

25. Slide 25 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Stress With our resources mobilized, we then fight the challenge during Phase 2, resistance. Temperature, blood pressure, and respiration remain high, and there is a sudden outpouring of stress hormones. If the stress is persistent, it may eventually deplete our body’s reserves during Phase 3, exhaustion. With exhaustion, we are more vulnerable to illness or even, in extreme cases, collapse and death.

26. Slide 26 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Extreme Stress Catastrophic floods, hurricanes, and fires are followed by increased rates of psychological disorders such as depression and anxiety. Those who experience significant life changes, such as the death of a spouse, divorce, or loss of a job, are vulnerable to disease. Experiencing a cluster of such crises puts one even more at risk.

27. Slide 27 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Extreme Stress Daily hassles, such as rush-hour traffic, long lines at the bank or store, and aggravating housemates, may be the most significant source of stress. Over time, these little stressors take a toll on our health and well- being.

28. Slide 28 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Extreme Stress Stress can increase the risk of coronary heart disease, the leading cause of death in many developed countries. It has been linked with the competitive, hard-driving, and impatient Type A personality. The toxic core of Type A is negative emotions, especially the anger associated with an aggressively reactive temperament.

29. Slide 29 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Extreme Stress Under stress, the body of the Type A person secretes more of the hormones that accelerate the buildup of plaques on the heart’s artery walls (epinephrin, norepinephrin, cortisol) The noncompetitive, relaxed, easy- going Type B personality is less physiologically reactive when harassed or given a difficult challenge and less susceptible to coronary heart disease. Pessimism and depression also can have a toxic effect on a person’s health.

30. Slide 30 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Health and Stress Management (Continued) Our emotional reaction to stress largely depends on how we interpret it. 30

31. Slide 31 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Style, Stress, & Health In comparison to pessimists, optimists report less fatigue, have fewer aches and pains, and respond to stress with smaller increases in blood pressure. Optimists also tend to outlive pessimists. Laughter (but not hostile sarcasm) may reduce stress and strengthen the immune system.

32. Slide 32 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Social Support & Stress Feeling liked, affirmed, and encouraged by intimate friends and family promotes both happiness and health. People with supportive friends and marriage partners eat better, exercise more, sleep better, and smoke less; thus they cope with stress more effectively.

33. Slide 33 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Social Support & Stress Social support strengthens immune functioning, calms the cardiovascular system, and lowers blood pressure. Even companionable pets help people cope with stressful events.

34. Slide 34 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Aerobic Exercise & Stress Aerobic exercise, sustained exercise that increases heart and lung fitness, can reduce stress, depression, and anxiety. It strengthens the heart, increases blood flow, keeps blood vessels open, and lowers both blood pressure and the blood pressure reaction to stress.

35. Slide 35 © 2008 The McGraw-Hill Companies, Inc. All rights reserved. Aerobic Exercise & Stress Research has linked aerobic exercise to higher levels of neurotransmitters that boost moods, to enhanced cognitive abilities, and to the growth of new brain cells in mice. One estimate suggests that moderate exercise adds two years to one’s expected life.
