CHAPTER 9 Flashcards
(109 cards)
At the turn of the 20th century, infectious diseases were the leading causes of death, but over the years, advancements in healthcare reduced the annual death toll from infectious diseases. Instead, the focus has shifted toward understanding the substantial impact of psychological and behavioral factors on health and well-being.
Psychological and Social Factors That Influence Health
Psychological and social factors wield a significant influence over an individual’s health. This influence stems from the intricate interplay between biological, psychological, and social elements. These factors not only affect mental health but also exert a tangible impact on brain structure, neurotransmitter functions, and gene expression. Stress, lifestyle choices, and the presence or absence of social support all play pivotal roles in overall health outcomes.
The Impact of Psychological and Social Factors on Health
Various physical disorders are strongly influenced by psychological and social factors. For instance, endocrinological disorders like diabetes are closely linked to lifestyle choices and the stress an individual experiences. Cardiovascular disorders are profoundly affected by chronic stress, specific behavior patterns, and even social isolation. Immune system disorders, notably AIDS, demonstrate the role of psychological stress in disease progression. While these disorders have identifiable physical causes, it is crucial to recognize the substantial contribution of psychological and social factors in their development and progression.
Physical Disorders Influenced by Psychological and Social Factors
The field has evolved from its earlier iteration as “psychosomatic medicine” to encompass a broader understanding of the interplay between biological, psychological, and social factors in all types of disorders. Throughout its history, the field has reached key milestones, including the recognition of the powerful mind-body connection and the realization that mental and emotional well-being significantly impact physical health.
The Evolution of the Field
Psychosocial factors play a pivotal role in both the etiology and treatment of physical disorders. Notably, research has unveiled the potential of reducing stress levels to improve overall health and longevity. The presence of a robust social network has proven instrumental in supporting healthy aging and promoting general well-being. Understanding the complex interplay of psychological and social factors in health is of paramount importance. These insights are not confined to mental health but extend to physical health as well. They emphasize the necessity of a holistic approach to healthcare, recognizing that psychological and social factors are integral components of overall well-being. Further research and awareness in this field are vital for improving health outcomes and advancing the understanding of the mind-body connection.
The Role of Psychosocial Factors in Health
_________ ____________is defined as the application of behavioral science to healthcare. It involves a multidisciplinary approach, with psychologists, physicians, and health professionals collaborating to integrate behavioral factors into health treatment and prevention strategies. This field recognizes the critical role of behavioral and psychological factors in healthcare, emphasizing their importance in diagnosis, treatment, and prevention.
Behavioral Medicine
__________ _______________is introduced as a specialized domain within psychology. It focuses on studying how psychological factors can be utilized for health promotion and maintenance.
Health Psychology
_______ _______________play a key role in analyzing healthcare systems and policies, aiming to enhance their effectiveness.
Health psychologists
The relevance of________ ____________ extends to understanding how the mind can contribute to both health improvement and the etiology of diseases.
Health Psychology
Delves into how psychological and social factors exert an influence on health. It highlights their profound impact on biological processes and behavior patterns, underlining their contribution to the origination and perpetuation of diseases. This emphasizes the critical link between our mental state, social environment, and physical well-being.
Psychological and Social Factors
Genital herpes and AIDS are explored as examples of diseases influenced by psychological and social factors. Psychological and behavioral elements play a significant role in the spread of genital herpes and the recurrence of herpes symptoms. Stress is discussed as a direct influencer of the immune system, potentially promoting disease progression in AIDS. Additionally, the text delves into behavioral risk factors associated with AIDS.
Diseases Influenced by Psychological and Social Factors
The relationship between lifestyle factors and prevalent causes of death, such as heart disease, cancer, and diabetes. Smoking is recognized as a leading preventable cause of death. It is significant to comprehend how psychological factors can impact physical disorders and diseases. Stress, as well as the neurobiological aspects of the stress response, emerges as pivotal areas for research and intervention in the context of health and healthcare. Understanding these links between the mind and the body is essential for improving overall well-being and public health outcomes.
Lifestyle Factors and Leading Causes of Death
Hans Selye’s groundbreaking experiments with rats, which inadvertently led to the identification of the physiological problems associated with stress. Selye observed that the daily injections he administered to rats were causing health issues and realized that these health problems were related to a nonspecific physiological reaction. This also introduces the term “stress” to describe this reaction, marking the birth of stress physiology.
Hans Selye’s Observations
According to _________ _________ __________, the body goes through three stages in response to sustained stress: alarm, resistance, and exhaustion. It is emphasized that chronic stress can lead to permanent bodily damage or contribute to the development of diseases. This concept revolutionized our understanding of how stress impacts the body’s physiological processes.
General Adaptation Syndrome (GAS)
Highlights the evolution of Selye’s theory in later years, with a focus on the confirmation and elaboration of the link between chronic stress and health problems. It underscores the enduring relevance of Selye’s work and its contributions to stress physiology.
The Modern Understanding of Stress
________ is defined as a physiological response to stressors, aligning it with the context of health and biology. A comparison is also drawn between this physiological perspective of stress and stress in engineering and everyday life.
Stress
__________ is recognized as a physiological response to stressors, and its profound influence on health underscores the need for continued research and awareness in this vital area of study.
Stress
Elucidating how the _________ _________ ________ primes the body for immediate action during threatening situations. It emphasizes the heightened strength and mental activity experienced during the stress response, illustrating the body’s readiness for action.
The Role of the Sympathetic Nervous System
With a special emphasis on the hypothalamic-pituitary-adrenocortical (HPA) axis. It explores the significance of neuromodulators and neuropeptides secreted by glands into the bloodstream to convey messages within the body.
The Endocrine System’s Role in Stress
introduces the concept of ________ __________, with a primary focus on cortisol. It elaborates on the intimate relationship between cortisol and the stress response, shedding light on the hormone’s critical role.
Stress Hormones
It emphasizes the role of the hippocampus in managing emotional memories and its vulnerability to cortisol. This section underscores the complex interplay between these systems.
The HPA Axis and the Limbic System
delves into the feedback loop between the limbic system and the HPA axis, highlighting how it functions in response to stress. It also addresses the potential repercussions of chronic stress and elevated cortisol levels, including hippocampal cell death.
Feedback Loop and Chronic Stress
explores the long-lasting consequences of chronic stress, such as brain damage and impaired problem-solving abilities. It discusses the link between hippocampal cell death and conditions like posttraumatic stress disorder and depression, emphasizing the far-reaching effects on mental health.
The discussion concludes by underscoring the importance of comprehending the physiological effects of stress and their potential implications for both physical and mental health.
