In this episode, we integrate key concepts from Unit 2, covering heat stress, acclimatization, and safety strategies. We discuss the mechanisms of heat exchange, physiological responses to acute heat stress, and the benefits of gradual acclimatization for improving thermoregulation and performance. Real-world scenarios, like athletes training in heat, illustrate the importance of hydration protocols, workload adjustments, and early recognition of heat-related illnesses. Emphasizing prevention and proactive planning, we highlight how to reduce risks and optimize safety in hot environments.
