This episode covers hypothermia, cold shock, and non-freezing cold injuries (NFCI). We break down the three stages of hypothermia (mild, moderate, severe), detailing symptoms and treatment strategies, including passive and active rewarming techniques. The cold shock response and its dangerous physiological effects in water immersion scenarios are also discussed. Lastly, we examine risk factors and prevention strategies, such as layering, limiting exposure, and recognizing early signs of cold-related illness.
