Which of the following is NOT a line of defense against hypothermia?

• A. Wearing multiple layers
• B. Avoiding alcohol consumption
• C. Engaging in strenuous activities
• D. Avoiding exposure

Answer: (C)

Engaging in strenuous activities is not considered a reliable line of defense against hypothermia. While physical activity can generate heat and temporarily raise body temperature, it can also lead to increased perspiration. This sweat can result in cooling as it evaporates, especially in cold environments. Furthermore, engaging in strenuous activities may cause fatigue, which can reduce the body’s ability to generate heat and increase vulnerability to the cold. In contrast, wearing multiple layers helps to insulate the body, avoiding alcohol consumption prevents the dilation of blood vessels that can lead to heat loss, and avoiding exposure limits the risk of being in cold environments altogether, all of which are effective methods for preventing hypothermia.
