Step-by-step explanation
The individual who is at the highest risk of exertional heat stroke is someone who is exercising in a hot and humid environment, especially if they are not acclimatized to those conditions. Additionally, factors that can increase the risk of exertional heat stroke include a lack of physical fitness, dehydration, certain medications or supplements, and underlying medical conditions.
Other factors that can increase the risk of exertional heat stroke include wearing heavy or dark clothing, being overweight or obese, and engaging in activities that require a high level of physical exertion, such as marathon running or military training. Therefore, it is important for individuals who are participating in activities in hot and humid environments to take appropriate precautions to prevent exertional heat stroke, such as staying hydrated, taking breaks in shaded or cool areas, and wearing appropriate clothing.
