Stress, Health, and Illness

Stress and Health

Overview of Stress

• Stress is a physiological and psychological response to perceived threats or challenges.

  • Example: A tough math test can be viewed as either a threat or a challenge depending on one's mindset.

  • Threat response: "Yikes! This is beyond me!"

  • Challenge response: "I've got to apply all I know."

Understanding Appraisal of Stress

• Appraisal refers to how individuals interpret stressors.

  • A stressful event leads to different responses based on whether it is perceived as a threat or a challenge.

  • Different responses include:

  • Stressed, distracted for threat perception.

  • Aroused, focused for challenge perception.

Definition of Stressors

• Stressors: Any event or stimulus that disrupts an individual’s equilibrium, leading to stress responses.

Responses to Stress

• The body has various responses to stress, which can include:

  • Psychological responses (anxiety, worry)

  • Physiological responses (increased heart rate, elevated blood pressure)

The Connection Between Stress and Disease Vulnerability

• Autoimmune Diseases Linked to Stress:

  • Psoriasis: A skin condition exacerbated by stress.

  • Dermatomyositis: An autoimmune disease affecting the skin and muscles.

  • Rheumatoid arthritis: An inflammatory autoimmune disorder affecting the joints.

  • Sjögren's syndrome: Affects moisture-producing glands.

  • Multiple sclerosis: A neurological disorder where the immune system attacks the nervous system.

  • Myasthenia gravis: A chronic autoimmune disease that affects nerve impulses.

  • Type 1 Diabetes Mellitus: Body’s immune system attacks insulin-producing cells.

  • Graves's disease: A disorder leading to overactivity of the thyroid gland.

  • Ulcerative colitis: A chronic inflammatory bowel disease.

  • Crohn's disease: A type of inflammatory bowel disease that affects the gastrointestinal tract.

Stress and Heart Disease

• Stress may increase the risk of developing heart disease through mechanisms such as:

  • Heightened physiological responses (e.g., increased heart rate, blood pressure).

  • Unhealthy coping behaviors (e.g., smoking, poor nutrition).

Stress and Inflammation

• Influences of Stress on Health:

  • Chronic anger, pessimism, or persistent feelings of depression contribute to stress-related health issues.

  • Effective stress responses can mitigate physical impacts such as:

  • Headaches

  • High blood pressure

  • Inflammation

  • Immune suppression

  • Notably, while stress itself may not directly cause illness, it increases vulnerability and alters physiology and behavior.

Addressing Stress

• Various strategies can be employed to manage stress effectively:

  • Exercise: Known to enhance mood and physical health.

  • Relaxation and Meditation:

  • Meditation has documented effects on modifying brain function and emotional regulation.

  • Altered traits include changes in mindset, brain, and body as seen in studies.

  • Spirituality and Faith: May provide a coping mechanism and enhance well-being.

The Issue of Control in Stress Responses

• Consideration of control vs. challenge:

  • Flow component of experience involves managing challenge level against skill level.

  • High control leads to better management of anxiety and results in states such as flow.

  • Emotional responses can vary based on the perceived balance between challenge and skill.

Optimism and Pessimism in Stress Management

• Understanding one's outlook affects how stress is managed.

  • An optimistic viewpoint can buffer stress impacts, whereas pessimism may exacerbate them.

Emotion Regulation

• Techniques to manage emotional responses to stressors are essential for overall health.

  • Skills in emotional regulation positively influence stress outcomes.
