Episode notes
Three-Layer Immune Architecture
- The immune system has three layered defenses: skin, mucus-lined openings, then innate and adaptive responses.
- These layers act sequentially to block, rapidly attack, and then specifically remember invaders.
Protect Mucus With Nasal Breathing And Ferments
- Maintain healthy mucus and microbiomes by nasal breathing, avoiding touching your eyes, and eating fermented foods.
- Aim for two to four servings daily of low-sugar fermented foods like sauerkraut, kimchi, or natto to support mucus health.
Sickness Behavior Is Purposeful
- Sickness behavior (lethargy, loss of grooming, photophobia) is a motivated state driven by vagus signaling to the hypothalamus.
- That signaling promotes fever and rest to optimize recovery rather than being mere malaise.
