Hypothermia: What you need to know

As body core temperature decreases, severe hypothermia sets in. You will be extremely weak, your skin will turn blue and eye pupils will become dilated. At this stage you will still deny that a problem exists and may become violent. Unconsciousness will gradually take over. Breathing will become so shallow that you will appear to be dead.

When hypothermia reaches this level, your only hope is to be taken to a medical facility where you can be warmed properly.

Diabetics often experience poor circulation. This makes them more prone to hypothermia because it is difficult for them to recognize numbness in their feet, arms and legs. Diabetics must be especially careful when outside in frigid temperatures.

Alcohol can also be a contributing factor in the onset of hypothermia. Alcohol numbs the senses and thins the blood. This makes it difficult for anyone under the influence to recognize the warning signs of hypothermia.

Hypothermia causes dehydration, which depletes the body of important nutrients. In most cases, this causes erratic heartbeat.

If you feel that you or someone you know may be experiencing the onset of hypothermia, call 911. Medical treatment is required immediately to prevent brain injury, heart attack or death.

Never attempt to bring a hypothermia victim's body back to normal temperature by placing him in hot water, giving him alcohol or wrapping him in an electric or hot blanket. If his body temperature rises too fast, it could induce cardiac arrest.

If someone is suspected of suffering from hypothermia, move him inside out of the elements. Remove wet or cold clothing and replace with clothes that are warm and dry. The victim should avoid all physical activity and lie in a prone position until medical help arrives.

Each year, hundreds of people in America suffer the adverse effects of hypothermia. Using your head, knowledge of your environment and dressing in layers can save your life. Severe hypothermia is often fatal. Don't become a statistic!
