The conversation also explores heat acclimation, particularly relevant for fighters and athletes competing in hot environments. French recommends gradual exposure—starting with short (5-minute) sauna sessions, progressing to longer durations—to enhance heat tolerance and sweating capacity. This not only protects against heat-related illnesses but also improves performance by enabling better thermoregulation. He notes that heat adaptation is achievable through consistent training and environmental exposure over several weeks, typically 8-10, with noticeable physiological improvements.
