Hypothermia is a state where the core temperature of the body is significantly lower than normal. This can happen if you are wet, exposed to heavy winds or have to sit still or lie down for a long period of time.

The body reacts even to small changes in the core body temperature. Normal body temperature is around 37.5°C when resting. When temperature falls below 35°C your body will start to shake and you will no longer have control of your muscles. Your ability to think rationally and concentrate will be affected.

If this hypothermic state persists, the shaking will decrease and then cease completely and you will then display signs of apathy and not be able to take care of yourself. Your ability to think clearly will disappear and you will not be able to answer simple questions. Advanced hypothermia is when the body temperature falls below 30°C.The person loses consciousness and it can be difficult to see if he/she is breathing or has a heartbeat.

In this situation the person must be handled with extreme care and professional medical care is necessary.

Check each other!

You are responsible for the other people in your group. Prevent hypothermia by making sure that everyone eats,drinks and constantly adapts their clothing to the weather.

Hypothermia gradually leads to a loss of mental and physical ability and it is one of the greatest dangers during a winter trek.
