What happens in the extreme late stage of hypothermia?

In the extreme late stage of hypothermia, one of the most critical changes that occurs is the absence of shivering. Shivering is the body's natural response to cold, as it generates heat through muscular activity. However, as hypothermia progresses and the body's temperature drops significantly, the physiological responses start to decline. Eventually, the body can no longer generate enough heat, and shivering ceases.

This indicates a severe state of hypothermia, where the body's mechanisms to maintain a stable temperature have failed. The person may appear lethargic and unresponsive, further emphasizing the seriousness of their condition. Recognizing this phase is crucial for providing proper medical intervention, as immediate help is needed to prevent further complications or potentially fatal outcomes. In contrast, the other options suggest states of warmth, activity, or abnormal fever responses that do not align with the body’s reaction in extreme hypothermic conditions.
