Episode notes
Exercise Preserves Immune Cell Energy
- Lifelong moderate training preserves immune cell energy capacity by improving mitochondrial function in natural killer cells.
- Trained cells rely more on aerobic metabolism, enabling decisive response without burning out the body.
Calmer Inflammation Speeds Recovery
- Master athletes show steadier inflammatory responses and return to baseline faster after challenges.
- Smaller, regulated inflammatory surges reduce fatigue, soreness, and lingering post-illness symptoms.
Build A Daily Movement Streak
- Start a daily movement streak with short sessions like 10 minutes brisk walking to train immune cells by repetition.
- Use predictable routines so cellular training compounds over time and builds resilience.
