When your body gets too cold, the natural defence mechanism is to try to keep the vital organs warm. In fact, the body pulls blood away from the extremities such as the arms and legs in an attempt to keep the rest of the body and more importantly, the vital organs of the heart and brain, warm.
If the body is exposed to extreme cold for a period of time, the individual could end up contracting severe frost bite or hypothermia. In more severe cases, it could even lead to death as the body becomes unable to pump blood and oxygen around the body to its vital organs.
A lot of people die when left in very cold water as the body stops pumping blood to their arms and legs. This means the muscles do not have enough glucose or oxygen in them to keep the individual moving. The body is trying to conserve as much energy as it possible can. In the same way, even on a normal day when a cool breeze blows and makes a person feel a bit cold, the hairs on their arms and legs may stand on end. This is sometimes known as ‘goose bumps’ and is the body’s way of trying to trap air to keep it well insulated and warm.
There are three stages of hypothermia. In severe cases where the individual contracts hypothermia, their body temperature can drop down as far as 32 degrees C in the worst cases. The person will have difficulty speaking and they may have trouble trying to use their arms and legs as the muscles have started to fade. The pulse rate may increase but their breathing may slow down. The major organs may then begin to fail and this could ultimately lead to death.
