Which of the following indicates hypothermia?

Hypothermia is defined as a condition where the core body temperature drops below the normal range, typically considered to be below 35°C (95°F). This drop in temperature can significantly impact both physiological and mental functions.

When the body's temperature falls, it struggles to maintain its normal metabolic processes, which can lead to symptoms such as shivering, confusion, and potentially life-threatening conditions if not addressed. The measurement of core body temperature is critical in diagnosing hypothermia; therefore, identifying a temperature below 35°C serves as a clear and objective indicator of this condition.

In contrast, symptoms such as shivering and numbness can be indicative of initial stages of hypothermia, but they are not definitive without temperature measurement. An elevated heart rate is often not associated with hypothermia; typically, as the body cools, the heart rate may decrease. Flushed skin can occur in other conditions, such as heat-related illnesses, but is not a sign of hypothermia. Thus, the most accurate indication of hypothermia is the confirmed core body temperature falling below 35°C.
