Introductory (College) Psychology: Health Psychology - Stress and Illness, Immune, Cardiovascular, Ulcers

Concept Summary

• Chronic stress can weaken the immune system, making individuals more susceptible to illnesses such as the common cold and flu.
• Prolonged stress can lead to cardiovascular disease, including high blood pressure, heart attacks, and strokes.
• Stress can cause the development of stomach ulcers by increasing the production of stomach acid and reducing the protective lining of the stomach.
• The hypothalamic-pituitary-adrenal (HPA) axis plays a crucial role in the body's response to stress, releasing hormones such as cortisol and adrenaline.
• Chronic stress can have a negative impact on mental health, contributing to anxiety and depression.

Questions

WHAT (definitional)

• Question: What is the hypothalamic-pituitary-adrenal (HPA) axis?
• Answer: The HPA axis is a complex neuroendocrine system that regulates the body's response to stress, releasing hormones such as cortisol and adrenaline.
• Real-world example: The HPA axis is activated when an individual experiences a stressful event, such as a public speech or a car accident.
• Misconception cleared: The HPA axis is not just responsible for stress response, but also plays a role in regulating other bodily functions, such as appetite and sleep.
• Question: What is the primary function of cortisol in the body?
• Answer: Cortisol is a hormone released by the adrenal gland that helps the body respond to stress by increasing blood sugar levels and suppressing the immune system.
• Real-world example: Cortisol levels increase in response to a stressful event, such as a job interview or a medical procedure.
• Misconception cleared: Cortisol is not just a "stress hormone," but also plays a role in regulating other bodily functions, such as metabolism and inflammation.
• Question: What is the difference between acute and chronic stress?
• Answer: Acute stress is a short-term response to a stressful event, while chronic stress is a prolonged response to ongoing stressors, such as work or financial problems.
• Real-world example: Acute stress might occur when an individual experiences a car accident, while chronic stress might occur when an individual is dealing with a long-term health issue.
• Misconception cleared: Chronic stress is not just a matter of "being stressed," but can have serious physical and mental health consequences.

WHY (causal reasoning)

• Question: Why does chronic stress increase the risk of cardiovascular disease?
• Answer: Chronic stress can lead to increased blood pressure, inflammation, and cardiovascular disease by activating the sympathetic nervous system and releasing stress hormones such as adrenaline.
• Real-world example: Studies have shown that individuals who experience chronic stress are more likely to develop cardiovascular disease, including high blood pressure and heart attacks.
• Misconception cleared: Chronic stress is not just a risk factor for cardiovascular disease, but can also contribute to other health problems, such as anxiety and depression.
• Question: Why does stress cause the development of stomach ulcers?
• Answer: Stress can cause the production of stomach acid to increase, while also reducing the protective lining of the stomach, leading to the development of stomach ulcers.
• Real-world example: Individuals who experience chronic stress are more likely to develop stomach ulcers, which can be painful and debilitating.
• Misconception cleared: Stress is not just a cause of stomach ulcers, but can also contribute to other gastrointestinal problems, such as irritable bowel syndrome.
• Question: Why does chronic stress weaken the immune system?
• Answer: Chronic stress can suppress the immune system by releasing stress hormones such as cortisol, which can interfere with the functioning of immune cells.
• Real-world example: Individuals who experience chronic stress are more likely to develop illnesses such as the common cold and flu.
• Misconception cleared: Chronic stress is not just a risk factor for illness, but can also contribute to other health problems, such as anxiety and depression.

HOW (process/application)

• Question: How does the HPA axis respond to stress?
• Answer: The HPA axis responds to stress by releasing hormones such as cortisol and adrenaline, which help the body respond to the stressor.
• Real-world example: When an individual experiences a stressful event, the HPA axis is activated, releasing cortisol and adrenaline to help the body respond.
• Misconception cleared: The HPA axis is not just a simple response to stress, but involves a complex interplay of hormones and neural pathways.
• Question: How does chronic stress contribute to the development of stomach ulcers?
• Answer: Chronic stress can cause the production of stomach acid to increase, while also reducing the protective lining of the stomach, leading to the development of stomach ulcers.
• Real-world example: Individuals who experience chronic stress are more likely to develop stomach ulcers, which can be painful and debilitating.
• Misconception cleared: Stress is not just a cause of stomach ulcers, but can also contribute to other gastrointestinal problems, such as irritable bowel syndrome.
• Question: How does chronic stress affect the immune system?
• Answer: Chronic stress can suppress the immune system by releasing stress hormones such as cortisol, which can interfere with the functioning of immune cells.
• Real-world example: Individuals who experience chronic stress are more likely to develop illnesses such as the common cold and flu.
• Misconception cleared: Chronic stress is not just a risk factor for illness, but can also contribute to other health problems, such as anxiety and depression.

CAN (possibility/conditions)

• Question: Can chronic stress contribute to the development of anxiety and depression?
• Answer: Yes, chronic stress can contribute to the development of anxiety and depression by activating the sympathetic nervous system and releasing stress hormones such as cortisol.
• Real-world example: Studies have shown that individuals who experience chronic stress are more likely to develop anxiety and depression.
• Misconception cleared: Chronic stress is not just a risk factor for anxiety and depression, but can also contribute to other health problems, such as cardiovascular disease.
• Question: Can stress cause the development of stomach ulcers in individuals who are not prone to them?
• Answer: Yes, stress can cause the development of stomach ulcers in individuals who are not prone to them by increasing the production of stomach acid and reducing the protective lining of the stomach.
• Real-world example: Individuals who experience chronic stress are more likely to develop stomach ulcers, even if they are not prone to them.
• Misconception cleared: Stress is not just a cause of stomach ulcers in individuals who are prone to them, but can also contribute to other gastrointestinal problems, such as irritable bowel syndrome.
• Question: Can chronic stress weaken the immune system in individuals who are otherwise healthy?
• Answer: Yes, chronic stress can weaken the immune system in individuals who are otherwise healthy by releasing stress hormones such as cortisol, which can interfere with the functioning of immune cells.
• Real-world example: Studies have shown that individuals who experience chronic stress are more likely to develop illnesses such as the common cold and flu.
• Misconception cleared: Chronic stress is not just a risk factor for illness in individuals who are otherwise healthy, but can also contribute to other health problems, such as anxiety and depression.

TRUE/FALSE (misconception testing)

• Statement: Stress can only cause physical health problems.
• Answer: FALSE
• Real-world example: Stress can also contribute to mental health problems, such as anxiety and depression.
• Misconception cleared: Stress can have a negative impact on both physical and mental health.
• Statement: Chronic stress is not a risk factor for cardiovascular disease.
• Answer: FALSE
• Real-world example: Studies have shown that individuals who experience chronic stress are more likely to develop cardiovascular disease, including high blood pressure and heart attacks.
• Misconception cleared: Chronic stress is a risk factor for cardiovascular disease, and can also contribute to other health problems, such as anxiety and depression.
• Statement: Stress can only cause stomach ulcers in individuals who are prone to them.
• Answer: FALSE
• Real-world example: Individuals who experience chronic stress are more likely to develop stomach ulcers, even if they are not prone to them.
