What This Episode Covers
Poor sleep is one of the fastest ways to age your body and tank your performance. In this episode, Austin dives into the science of core body temperature and reveals the exact protocol he uses to achieve consistently deep, restorative sleep. Learn how saunas can be your secret weapon for fixing your sleep tonight.
The Core Body Temperature Protocol
Your core body temperature naturally drops in the evening, signaling to your body that it's time to sleep. By strategically using a sauna 2–3 hours before bed, you create a rapid cooling effect that amplifies this natural drop. Austin breaks down:
- Why timing matters more than duration
- The ideal temperature and session length for sleep optimization
- Why the post-sauna cool-down is where the magic happens
- How to stack this with other sleep protocols for maximum effect
The 5 Key Takeaways
- Core Temperature Drop Triggers Sleep — A 1-2°C drop in core body temperature signals deep sleep onset. Saunas create this effect predictably.
- Timing Is Everything — Use the sauna 2–3 hours before bed, not right before. Your body needs time to cool and recover.
- Recovery Matters More Than Heat — The cooling phase after leaving the sauna is where deep sleep gains happen. Don't rush back inside.
- Consistency Builds Sleep Architecture — 3 sessions per week provides sustainable sleep improvements without overdoing it.
- This Stacks With Other Protocols — Combine with dark rooms, cool temps (65-68°F), and no screens 1 hour before bed for elite sleep performance.
