Being able to keep warm is important, but along with that, so is being able to recognize the early warning signs of hypothermia. It doesnt have to be cold outside, hypothermia can begin in fairly mild conditions.
I had an experience this summer while fishing, a front came through, dropping temps to 65-70 degrees, along with 15-20 mph winds and rain. By the time we got to the dock after a 5 mile run in 4 ft waves, I was soaked to the bone and shivering. It was starting.
Early signs are subtle. Cold and /or pale hands,feet, ears, nose, or head are signs the body is shunting blood away from the periphery to maintain core heat. This is followed by shivering, increasing to an uncontrollable level. Loss of finger dexterity, and coordination soon follows. As blood is re-directed away from the extrmities muscle control and coordination fails.
Next, as the brain starts to cool, confusion begins, leading eventually to sleepiness and finally unconsciousness. Death isnt far behind.
You or your partner may have start showing signs by slowing your pace, drowsiness, stumbling more often, slurred or difficult speech. Irritability, hallucinations,or loss of perceptual contact with your environment may occur. Decreased shivering and muscle rigidity.
Late signs of a grave condition may include blue skin, dilated pupils, and decreased heart and rspiratory rates.
This is as urgent a medical emergency as a heart attack. With out treatment, death is likely.
Ok, so what to do? Get yourself or your partner out of the elements. Remove wet or froen clothing, keep dry and wrap in blankets or extra clothes. Call for help.
DO NOT POUND OR BEAT ON arms, legs or torso! Rough handling of severe hypothermia patients can trigger a fatal heart arrythmia.
Get the person to a hospital if symptoms are severe.
The problem with hypothermia is, it can cloud your ability to recognize serious symptoms. You tend to tough it out, until all of a sudden you cant stop shivering, you stumble and have trouble speaking. Your dexterity in your hands is failed or failing fast, and you cannot start a fire, or use your keys to start your car.
If you notice early symptoms, get indoors, warm up and prevent getting into serious trouble.Always carry a means to start a fire, or to get warm.
