What are the symptoms indicating someone may be suffering from hypothermia?

When assessing symptoms of hypothermia, it's important to recognize the body's response to extreme cold exposure. Shivering is a primary response as the body attempts to generate heat through muscle activity. Confusion can arise due to the effects of cold on brain function, impairing decision-making and cognitive abilities. Cold skin is a direct indicator that the body is losing heat and is unable to maintain a normal temperature, which is critical in identifying someone who may be in danger of hypothermia.

The other symptoms listed in the alternative choices do not align with the physiological responses associated with hypothermia. Elevated heart rate and excessive sweating are more typical of conditions like heat exhaustion, while increased energy and warmth contradict the very essence of hypothermia, where individuals typically exhibit decreased bodily functions. Similarly, headaches and stomach cramps can be symptoms of other medical conditions, not specifically linked to hypothermia. Recognizing the correct symptoms allows lifeguards and responders to act swiftly and appropriately in potentially life-threatening situations.
