Study Notes
Overview of Stress
- Eustress: Positive form of stress that stimulates and motivates individuals.
- Distress: Negative stress that causes anxiety and adversely affects well-being.
- Mind-Body Connection: Emotional, psychological states influence physical health and vice versa.
Physical Responses to Stress
- Acute Stress: Short-term response to immediate threats; intensity varies and subsides once the threat is removed.
- Chronic Stress: Long-standing response leading to sustained psychological and physiological impacts, linked to various diseases.
Selye’s Stress Response Theory
- Stressors challenge body adaptability; maintaining homeostasis is crucial.
- General Adaptation Syndrome: Comprises three stages - Alarm, Resistance, and Exhaustion.
Nervous System Response
- Activation of Sympathetic Nervous System (SNS): Triggers "Fight or Flight" response.
- Increases in heart rate, respiratory rate, alertness, and blood flow to muscles; decreases towards the GI tract and genitourinary system.
Endocrine Responses
- Adrenal Cortex: Releases cortisol, vital for increasing blood sugar and immune system modulation.
- Adrenal Medulla: Releases epinephrine and norepinephrine during stress.
- Posterior Pituitary: Releases anti-diuretic hormone (ADH), leading to decreased urine output and increased blood volume.
Stress Response Stages
- Resistance Stage: Ongoing response; relaxation occurs if stress abates, otherwise, the body's adaptive capacity declines.
- Exhaustion Stage: The body cannot sustain the stress response, leading to health deterioration and increased infection risk.
McEwen’s Stress Response Theory
- Allostasis: The process of achieving stability through change; frequent stressors alter physiological "setpoints," e.g., chronic stress may lead to hypertension.
Allostatic Load
- Represents cumulative wear on the body systems due to stress; reflects individuals' adaptive responses and prolonged stress reactions.
Societal Pressures and Stress
- Structural Racism: Societal systems that perpetuate racial inequities, contributing to health disparities and stress-related disorders.
Common Stress-Related Disorders
- Conditions include asthma, hypertension, atherosclerosis, autoimmune diseases, migraines, and diabetes.
Treatment of Stress: Lifestyle Practices
- Reducing caffeine, ensuring restorative sleep, engaging in psychotherapy, practicing yoga, maintaining work-life balance, and seeking social support are beneficial strategies.
Role of Serotonin and Tryptophan
- Serotonin: Neurotransmitter affected by stress; low levels can cause gastrointestinal upset and anxiety.
- Tryptophan: Amino acid that leads to serotonin production, with carbohydrate intake enhancing its uptake in the brain.
Pharmacological Treatments for Stress
- Sedatives: CNS depressants that induce relaxation, including alcohol.
- Antidepressants: Influence neurotransmitter levels and take approximately three weeks for therapeutic effects.
Benefits of Exercise
- Recommended 40 minutes of exercise several times a week; important to consult healthcare professionals if underlying conditions exist.
- Promotes healthier physiology through adaptations in various body systems.
Impact of Exercise vs. Inactivity
- Cardiovascular: Exercise lowers blood pressure and reduces cardiovascular disease risk; inactivity leads to heart deconditioning.
- Pulmonary: Increased oxygenation with exercise versus the risk of atelectasis and decreased function with inactivity.
- Musculoskeletal: Exercise enhances muscle strength and bone density; inactivity results in muscle loss and potential fractures.
Effects of Inactivity
- Risks of venous stasis, urinary stasis, gastrointestinal issues, and musculoskeletal problems arise from immobility.
Integumentary System Effects
- Prolonged immobility can lead to bedsores and decubitus ulcers, classified into four stages, requiring frequent repositioning and management.
Clinical Considerations
- Stressors from surgery, medication effects (e.g., cortisone), and immobility-related complications highlight the interplay between physical and psychological stress factors.
