Week 3

Introduction to Stress and Coping

This week’s focus is on stress and coping, with the key learning outcomes including:

1. Understanding how stress impacts physical and mental health, including both acute and chronic stress and their connection to disease.

2. Exploring models of stress coping, particularly the transactional model by Lazarus.

3. Recognizing the benefits of stress, reframing it from a solely negative viewpoint to an understanding of its evolutionary purpose.

Importance of Understanding Stress

Recognizing the prevalence of stress in everyone’s lives is critical for those training in health fields. From a health professional perspective, understanding stress is essential because it is universally experienced, varying in sources and expressions among individuals.From a personal standpoint, understanding stressors and coping mechanisms helps navigate significant life challenges, enhancing resilience.

The Nature of Stress

Defining stress can be complex due to varied interpretations across fields (e.g., mental health, medical, education). Empirically, stress is recognized as a physiological change disrupting homeostasis, impacting the body's balance and stability.

Neurophysiological Responses

The hypothalamic-pituitary-adrenal (HPA) axis plays a crucial role in stress responses. When activated, it releases hormones like cortisol, altering bodily functions and behavioral responses. The body subsequently undergoes a rebalancing process called allostasis, which is essential for returning to homeostasis after a stressor.

Types of Stress

1. Acute Stress: Short-lived experiences of stress (e.g., exams, deadlines) are manageable and can promote adaptive responses in preparation for future stressors.

2. Chronic Stress: Persistent stress without relief can lead to significant health challenges since the body remains in a heightened state without the chance to regulate.

General Adaptation Syndrome

This model illustrates how stress affects individuals in three stages:

1. Alarm Stage: Initial stress response activation.

2. Resistance Stage: Efforts to return to homeostasis.

3. Exhaustion Stage: Prolonged stress leading to fatigue and health issues.

Coping Strategies in Response to Stress

Understanding coping involves recognizing demands perceived as exceeding one’s resources.

Types of Coping Strategies

1. Problem-Focused Coping: Directly addressing and altering the stressor through confrontation, planning, or seeking support.

2. Emotion-Focused Coping: Altering emotional responses, which may include distancing, positive reappraisal, or self-control.

Effectiveness of Coping Strategies

Research indicates that active problem-focused coping generally results in better mental health outcomes compared to avoidant strategies. However, the effectiveness may vary based on stressor specifics, emphasizing that there is no one-size-fits-all approach.

Transactional Model of Stress

Lazarus' transactional model posits that stress arises from an individual's appraisal of a stressor and the resources available to cope with it. The appraisal process includes evaluating the threat, potential loss, and individual capabilities.

Emotional Repercussions of Appraisal Processes

Different emotional responses may stem from distinct appraisal components, such as anxiety from threats or hope from challenge assessments.

Impact of Stress on Physical Health

Exploring the link between stress and chronic diseases:

1. Cancer: Mixed evidence exists regarding stress contributing to cancer development.

2. Heart Disease: Evidence shows a clearer link between stress and heart-related issues.

3. Infectious Disease: Stress is associated with lowered immune response and increased illness susceptibility.

Conclusion

Understanding stress and coping mechanisms helps preserve mental health and improve well-being. As we navigate various stressors, it's crucial to employ appropriate strategies tailored to individual circumstances.
