Study Notes
General Adaptation Syndrome (GAS)
- Introduced by Hans Selye, GAS describes the body's three-stage response to stress:
- Alarm Phase: Fight-or-flight response, activated by hypothalamus, sympathetic nervous system, adrenal medulla.
- Resistance Phase: Body attempts to restore balance after stressor is removed.
- Exhaustion Phase: Prolonged stress without recovery leads to health issues like chronic inflammation, immune suppression, cortisol dysfunction.
HPAA Axis (Hypothalamic-Pituitary-Adrenal Axis)
- Chronic HPAA activation disrupts cortisol feedback, leading to inflammation and conditions like cardiovascular disease and depression.
- High cortisol levels impair insulin sensitivity, increase visceral fat, disrupt reproductive and immune functions.
Inflammation and Oxidative Stress
- Chronic stress increases inflammatory markers and oxidative stress, contributing to damage and diseases like rheumatoid arthritis and fibromyalgia.
Mitochondrial Dysfunction & Fatigue
- Mitochondria generate ATP (energy), dysfunction leads to fatigue, impaired organ function, and increased risk of chronic fatigue syndrome (CFS).
- Nutrient deficiencies, toxins, and oxidative stress compromise mitochondrial function.
Chronic Fatigue Syndrome (CFS) and Myalgic Encephalomyelitis (ME)
- Characterized by prolonged fatigue, muscle pain, cognitive impairment due to impaired energy delivery, mitochondrial dysfunction, and inflammation.
Key Supplements and Nutrients for Stress Management
- Vitamin C: Strong antioxidant, especially for CNS; reduces stress-induced free radical damage and cortisol levels, enhances immune response.
- Vitamin B5: Essential for adrenal cortex function, aids in production of adrenal hormones.
- Vitamin B6: Modulates neurotransmitters like GABA and serotonin, improving mood and reducing stress.
- Vitamin B Complex: Supports nervous system and energy production through the Krebs cycle.
- Magnesium: Attenuates HPAA activity, reducing cortisol; crucial for GABA synthesis, muscle relaxation, and serotonin-melatonin pathway.
- Phosphatidylserine: Normalizes stress response by buffering the HPAA, reducing cortisol and enhancing mood & sleep.
- L-theanine: Found in green tea; increases GABA, dopamine, and serotonin, promoting relaxation without drowsiness.
- Adaptogens like Rhodiola and Ashwagandha: Help modulate stress response, enhancing adaptation, reducing fatigue, and improving mood and resilience.
