Changes in heart rate (pulse) are logical symptoms of hypothermia. Body temperature can affect even the way our heart works. It is hard for the primary organ to survive the low temperatures. It is an unbelievable stress. Because of the restricted blood flow, the patient may feel his heart running too fast or vice versa. This organ requires more oxygen, so the person may feel breathless as well.
Problems with breath are the outcomes of the fact that patients diagnosed with hypothermia experience problems with heart rate. As the blood flow is limited, the heart stops achieving required amount of oxygen. It prevents the person from breathing in a regular manner. During the acts of breathlessness, the person may start trembling and shaking – that is the initial symptom of the disease. Blood pressure also goes up, causing this discomfort.
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.
