In extreme cold weather, CHS personnel may see an increase in which type of injuries?

• A. dehydration
• B. cold injuries (frostnip-severe frostbite, hypothermia)
• C. heat exhaustion
• D. combat stress

Answer: (B)

Extreme cold exposure drives a rise in cold-related injuries because the body's first response is to conserve heat, causing blood vessels to constrict and skin and exposed tissues to lose heat quickly. That environment makes tissues susceptible to freezing and body temperature to drop, leading to frostnip and frostbite in the extremities and to hypothermia if core temperature falls. Frostnip is the milder, early stage of freezing injury—numbness and pale skin that can be reversed with gradual warming. Frostbite involves actual freezing of tissue and can damage skin and deeper structures, potentially requiring medical care if severe. Hypothermia is a systemic condition where the core temperature falls, resulting in shivering, confusion, slowed movements, and eventually organ impairment if not addressed. dehydration can occur in cold weather, but it is not an injury type driven by cold exposure. Heat exhaustion is a heat-related illness from high temperatures, not extreme cold. Combat stress, while possible in any environment, is a different kind of condition and not a cold‑injury in the same sense. The injuries most associated with extreme cold are the cold-related injuries described.
