Episode notes
Use Cold Therapy Based On Training Context
- Use cold therapy contextually: apply cryo/cold immersion to reduce excessive inflammation after very strenuous training.
- Avoid routine cold immediately after light workouts if hypertrophy is your goal, because it can blunt growth signals.
Cold Exposure Robustly Raises Norepinephrine
- Whole-body cold or immersion triggers a robust 2–3x increase in norepinephrine that persists across repeated sessions.
- Norepinephrine improves attention, mood, analgesia, and reduces inflammation centrally and peripherally.
Biological Age Diverges Widely By Your 30s
- Biological aging diverges strongly by mid-30s: people same age showed cellular ages ±10 years.
- Physical appearance correlated with measured biological age, linking lifestyle to cellular aging.
