Understanding Stress

• Eustress: Positive stress that motivates and enhances well-being.

  • Associated with positive feelings, optimal health, and performance.

  • Moderate stress can improve performance and recall of educational material, as shown in studies by Hupbach & Fieman (2012).

• Distress: Negative stress that is debilitating and counterproductive.

  • Occurs when stress levels exceed optimal levels, leading to fatigue and burnout.

  • Example: Severe test anxiety can impair concentration and negatively affect scores.

Stress and Performance Curve

• Performance increases with moderate stress until an optimal level is reached, after which excess stress causes performance to decline.

Prevalence of Stress

• Stress levels have been rising; nearly half of U.S. adults report increased stress over five years (Neelakantan, 2013).

• Common sources of stress include financial difficulties, job pressures, and personal crises (e.g., failing to prepare for an important exam).

Physiological and Psychological Responses to Stress

• Responses to stress can be:

  • Physiological: Accelerated heart rate, headaches, gastrointestinal issues.

  • Cognitive: Difficulty in concentration and decision-making.

  • Behavioral: Increased substance use, avoidance behaviors.

• Chronic stress is linked with various illnesses including cardiovascular diseases (Cohen & Herbert, 1996).

Health Psychology

• Health psychology is dedicated to understanding how psychological factors influence health, illness, and responses to being ill (Taylor, 1999).

• Aims to bridge the gap between physical health and psychological influences.

Identifying At-Risk Groups

• Differences in stress levels can be measured by demographic factors such as income, education, and employment status.

• Studies suggest women generally report higher stress levels than men, while the unemployed have consistently high stress levels across various demographics (Cohen & Janicki-Deverts, 2012).

Historical Perspectives on Stress

• Pioneers like Walter Cannon and Hans Selye contributed to our understanding of stress responses:

  • Fight-or-Flight Response: Cannon's concept outlining the body's physiological reaction to stress.

  • General Adaptation Syndrome: Selye's model of stress response comprising three stages:

    1. Alarm Reaction: Immediate response to stressor.

    2. Resistance Stage: Adaptation to ongoing stress.

    3. Exhaustion Stage: Depletion of resources leading to health deterioration.

Physiological Mechanisms of Stress

• Key bodily systems involved:

  • Sympathetic Nervous System: Activates the fight-or-flight response.

  • HPA Axis: Triggers cortisol release; prolonged activity can weaken the immune system.

Psychological and Emotional Effects of Stress

• Stress can lead to psychological disorders, including PTSD, depression, and anxiety (Cohen et al., 1998).

• Individuals coping with stress often show symptoms connected to physical health risks, including heart disease and weakened immune function.

Regulation and Coping with Stress

• Effective stress coping strategies fall into two categories:

  • Problem-Focused Coping: Managing or altering the source of stress (e.g., studying for a test).

  • Emotion-Focused Coping: Reducing negative emotional responses (e.g., distraction, mindfulness).

• Social support plays a crucial role in stress management and health outcomes (Uchino, 2009).

The Connection Between Stress and Happiness

• Happiness involves greater emotional well-being, resilience, and engagement in fulfilling activities.

• Enhancing life satisfaction often involves managing stress effectively, pursuing meaningful experiences, and maintaining strong social ties.
