(Music playing). What is you probably you do not realize it. But hypothermia kills more people and the wilderness and out burst setting than any other kind of situation. Hypo means depress, thermia means temperature and that is exactly what happens to body temperatures start to fall but typically the cold temperature. So that is what is going on. When thus it occur? It occurs in situation that may seems quite settle. And maybe wet or maybe raining. You maybe wet from perspiration, you maybe out winter cold. Any numbers of situations that causes to occur or maybe you are fell in the water and of course it makes it happen very rapidly. So now, what do you see? What are the sign of this as it begins to happen. Speech becomes sword, people start to stumble they are not coherent. Hey, look a little bit like they are drunk. So if you see this happening when you out of on a party this what to do. I think we have a worry about as hypothermia victim. And if she still moving and has not come along to far with it too much of that dropping cold temperature. We need to add some clause but typically a cap on her head or a scarf on under neck and close on her hands. Because those are, areas are great heat leakage. Now if she is gone to the point or we need to lye her down and we need more close for the airway we can get our hands on the insulator from the grown. At the point then, we want to prepare hot drink and food that are very much on a sure you decide in order to bring her blood sugar level backup. Then a sleeping bag and heat water to fell our water bottles and also heat small rock wrap it into a cold some item like that and get those in the bag with and sit that bag up and she were really warm very rapidly.
