Alternating between sauna heat (15-20 min at 170-200°F) and cold plunge (2-5 min at 40-50°F) for 2-3 rounds. The temperature cycling creates a cardiovascular workout, flushes inflammation, and triggers massive endorphin and growth hormone release. r/Biohacking considers this the 'cheat code' for recovery and mood.
