Why Sauna's Work

What's the secret to maximizing sauna benefits? Most people assume wet and dry saunas deliver similar results. Biohacker Bryan Johnson, who spends millions optimizing his biology, discovered why dry Finnish saunas are dramatically superior for longevity and performance when compared to wet saunas.
The difference lies in temperature gradients. Dry sauna hits your skin at 40°C within minutes while your core creeps up only 1°C. That forces your heart to pump 70% more blood - mimicking zone 3 cardio without moving a muscle. Your body produces up to 1 kg of sweat per hour for detoxification while activating heat shock proteins that boost cellular resilience.

The conclusion:
Dry saunas lead to: 1. Enhanced Blood Flow, 2. Increased Sweating / Detox, 3. Improved Heat Tolerance, 4. Activation of Heat-Shock Proteins, and 5. Longer Exposure at Higher Temperatures. Wet saunas can't match this intensity. Stop settling for steam rooms. Start optimizing with Finnish precision. Your cardiovascular system will thank you decades later.
