Your Immune System Listens to Your Nerves
Your immune system is not floating alone; it listens to your nervous system every day.
The Science
- The immune and nervous systems talk both ways, with the vagus nerve as one route.
- Stress signals can shift inflammation, while sleep and safety signals support repair.
- The body reads context, so recovery basics act as real biological signals, not moral tests.
The Protocol
- Protect sleep, hydration, real food, sunlight, gentle movement, and support during hard weeks.
- Use slow breathing when stress is high to shift body state.
- Seek medical care for serious symptoms; that is a power move, not weakness.
