People under the threat of hypothermia may feel tired and exhausted. The brain cannot function as it should due to the irregular temperatures. It may simply ‘shut down,’ so the person may feel rather weak or no energy at all. Fatigue and drowsiness follow these patients everywhere. Usually, this is the symptom of medium and severe hypothermia rather than a mild one.

People who may suffer from hypothermia reject the daily routine. They feel apathetic, without having any desire to do anything. It often leads to failures in education, work, or other daily activities. They lack emotions as the brain stops working as it should due to the drops in body temperature. Full mental numbness characterizes this condition the best. Such individuals demonstrate entire absence of concern about their own lives, families, and environment.
