Hypothermia
Hypothermia happens when your body temperature drops. Many reasons can make this happen, including rain and cold weather. It can also happen in temperatures as warm as 60 degrees F. Your body has many built in functions to help it regulate its temperature, including shivering and sweating. Increasing or decreasing your current activity will also play a role in your body temperature.
Some classic signs for hypothermia include shivering uncontrollably, complex motor functions are absent, and vasoconstriction has occurred. It is easy to watch for the "Umbles" . . . stumbles, mumbles, fumbles and grumbles, which will show changes in motor function and levels of consciousness. These people need to be re-warmed quickly.
Remove any wet clothing, as you will lose 25% more heat with wet clothing. Leave dry clothing in place and wrap the person in blankets. If they are able to swallow, warm sugar water can be given to them. The sugar will allow for quick bursts of energy and the warm water is just that, warm. The stomach can absorb these two items when hypothermic. The bursts of energy will help generate heat. Carbohydrates will provide longer bursts of energy and may take a little longer to absorb, and proteins will provide long lasting release of energy. It is wise to vary these kinds of liquids and foods to that energy is being released gradually and for a period of time.
Also remember to consult a family doctor, ER, or call 9-1-1 when faced with this type of emergency. Dress in layers that can be easily removed or added when necessary. In severe cases, death can occur.
