Figure 11.1 General Adaptation SyndromeThe diagram at the top shows some of the physical reactions to stress in each of the three stages of the general adaptation syndrome. The graph at the bottom shows the relationship of each of the three stages to the individual ’s ability to resist a stressor. In the alarm stage, resistance drops at first as the sympathetic system quickly activates. But resistance then rapidly increases as the body mobilizes its defense systems. In the resistance stage, the body is working at a much increased level of resistance, using resources until the stress ends or the resources run out. In the exhaustion stage, the body is no longer able to resist as resources have been depleted, and at this point disease and even death are possible.

Stress and the Immune System
• Immune system: cells, organs, and chemicals of the body that respond to attacks from diseases, infections, and injuries– negatively affected by stress
• Psychoneuroimmunology: the study of the effects of psychological factors on the immune system

Stress and the Immune System
• Heart disease: stress puts people at higher risk for coronary heart disease (CHD)
• Diabetes: type 2 diabetes is associated with excessive weight gain– occurs when pancreas insulin levels become
less efficient as the body size increases
• Cancer: stress increases malfunction of natural killer (NK) cell – NK cell: responsible for suppressing viruses and
destroying tumor cells

Figure 11.2 Stress Duration and IllnessIn this graph, the risk of getting a cold virus increases greatly as the months of exposure to a stressor increase. Although a stress reaction can be useful in its early phase, prolonged stress has a negative impact on the immune system, leaving the body vulnerable to illnesses such as a cold. Source: Cohen et al. (1998).

Figure 11.3 Stress and Coronary Heart DiseaseThe blue box on the left represents various sources of stress (Type A personality refers to someone who is ambitious, always working, and usually hostile). In addition to the physical reactions that accompany the stress reaction, an individual under stress may be more likely to engage in unhealthy behavior such as overeating, drinking alcohol or taking other kinds of drugs, avoiding exercise, and acting out in anger or frustration. This kind of behavior also contributes to an increased risk of coronary heart disease.

Cognitive Factors of Stress

Psychology, Third EditionSaundra K. Ciccarelli • J. Noland White
Cognitive Factors of Stress
• Cognitive appraisal approach– primary appraisal: involves estimating the
severity of a stressor and classifying it as either a threat or a challenge
– secondary appraisal: involves estimating the resources available to the person for coping with the stressor

Psychology, Third EditionSaundra K. Ciccarelli • J. Noland White
Figure 11.4 Responses to a StressorLazarus’s Cognitive Appraisal Approach. According to this approach, there are two steps in cognitively determining the degree of stress created by a potential stressor. Primary appraisal involves determining if the potential stressor is a threat. If it is perceived as a threat, secondary appraisal occurs in addition to the bodily and emotional reactions. Secondary appraisal involves determining the resources one has to deal with the stress, such as time, money, physical ability, and so on. Inadequate resources lead to increased feelings of stress and the possibility of developing new resources to deal with the stress.

Figure 11.5 Personality and Coronary Heart DiseaseThe two bars on the left represent men with Type A personalities. Notice that within the Type A men, there are more than twice as many who suffer from coronary heart disease as those who are healthy. The two bars on the right represent men with Type B personalities. Far more Type B personalities are healthy than are Type A personalities, and there are far fewer Type B personalities with coronary heart disease when compared to Type A personalities.Source: Miller et al. (1991, 1996).

Become More Optimistic
1. When a bad mood strikes, stop and think about what just went through your head.
2. When you’ve recognized the negative statements, treat them as if they came from someone else—someone who is trying to make your life miserable. Think about the damage the statement is doing to you.
3. Argue with those thoughts.
