Which of the following is NOT a type of cold weather injury?

Heat exhaustion is not a type of cold weather injury because it occurs when the body overheats, typically in warm or hot environments. It results from the body's inability to regulate its temperature due to excessive heat and can manifest symptoms such as heavy sweating, weakness, dizziness, and confusion. In contrast, hypothermia and frostbite (both superficial and deep) are injuries related to exposure to cold temperatures. Hypothermia occurs when the body loses heat faster than it can produce it, leading to a dangerously low body temperature. Superficial and deep frostbite are injuries caused by freezing of body tissues, with superficial frostbite affecting only the skin and deep frostbite impacting deeper structures, potentially leading to severe tissue damage. This distinction makes heat exhaustion an anomaly in a list primarily focused on cold weather-related conditions.
