What is Hypothermia

You may have heard about many cases of people who collapse in the intense heat of the sun. When this happens, people complain that they are suffering from problems like dizziness, physical fatigue and exhaustion. The problem is that of hyperthermia and its main adversity is dehydration or reduction of water levels in the human body. But do you know about hypothermia? Well, it is the condition that is borne out of a reduction of the body temperature. This happens especially when it is rather cold and the body fails to regulate the normal temperature. When such a thing happens, the person would suffer from a number of physical and mental problems.

When it is severely cold and windy, the body would still be able to regulate its normal temperature which should be ideally about 37 degrees celsius. Minor fluctuations in the range would be completely normal. However, hypothermia sets in when the temperature of the body declines steadily below the given range of temperatures. There are also many types of hypothermia.

The first type of hypothermia is known as mild hypothermia. This condition is not marked by any dramatic or drastic fall in the body heat. At the most, there will be slight fluctuations beyond the range of normal temperatures. The symptoms observable are most of the human body’s reactions to the general feeling of cold. There will be shivering and also hypertension. However, there could also be other effects like diuresis, which is the rapid and involuntary passing of urine and other fluids in the body. There will also be some mental confusion and also high level of sugar in the blood, as it is not used by the cells and tissues in the body.

As the condition progresses to a slightly greater intensity, the body temperature begins to decline from 28 to 32 degrees. This sees the individual now shivering profusely and violently. The confusion and mental imbalance may become slightly more profound. Parts of the human skin and the veins and arteries may also become blue. When the person begins to suffer from the severe hypothermia, the situation further worsens and it leads to dizziness, physical numbness, profound mental confusion and also marked failure in the functioning of the crucial organs. In the most extreme cases, the individual may die or become insane almost to the point of undressing himself or hiding in closed and snug spaces.

There have been no real causes to be identified for the problem of hypothermia. Severe winter can be one of the causes. But the loss of heat in the body results from some factors. One of them is alcohol or water which help a person to feel warm but actually bring down the heat in the body. The best cure would be to use warming fluids and other such medicines. These help to bring up the temperature of the body back to normal. The individual should keep them handy when he is facing winter and a windy weather. These should be immediately used when a person begins to fall prey to the problem of hypothermia and its different stages.
