“I’m Freezing To Death”

With the cold snap hitting most of the country, you're likely to hear that phrase.  But if you want to know what it is really like to freeze to death, read here.  It's horrifying.  Not at all like the supposedly "pleasant" experience of drowning.  An excerpt:

As you sink back into the snow, shaken, your heat begins to drain away at an alarming rate, your head alone accounting for 50 percent of the loss. The pain of the cold soon pierces your ears so sharply that you root about in the snow until you find your hat and mash it back onto your head.

But even that little activity has been exhausting. You know you should find your glove as well, and yet you're becoming too weary to feel any urgency. You decide to have a short rest before going on.

An hour passes. at one point, a stray thought says you should start being scared, but fear is a concept that floats somewhere beyond your immediate reach, like that numb hand lying naked in the snow. You've slid into the temperature range at which cold renders the enzymes in your brain less efficient. With every one-degree drop in body temperature below 95, your cerebral metabolic rate falls off by 3 to 5 percent. When your core temperature reaches 93, amnesia nibbles at your consciousness. You check your watch: 12:58. Maybe someone will come looking for you soon. Moments later, you check again. You can't keep the numbers in your head. You'll remember little of what happens next.

Your head drops back. The snow crunches softly in your ear. In the minus-35-degree air, your core temperature falls about one degree every 30 to 40 minutes, your body heat leaching out into the soft, enveloping snow. Apathy at 91 degrees. Stupor at 90.

You've now crossed the boundary into profound hypothermia. By the time your core temperature has fallen to 88 degrees, your body has abandoned the urge to warm itself by shivering. Your blood is thickening like crankcase oil in a cold engine. Your oxygen consumption, a measure of your metabolic rate, has fallen by more than a quarter. Your kidneys, however, work overtime to process the fluid overload that occurred when the blood vessels in your extremities constricted and squeezed fluids toward your center. You feel a powerful urge to urinate, the only thing you feel at all.

By 87 degrees you've lost the ability to recognize a familiar face, should one suddenly appear from the woods.

At 86 degrees, your heart, its electrical impulses hampered by chilled nerve tissues, becomes arrhythmic. It now pumps less than two-thirds the normal amount of blood. The lack of oxygen and the slowing metabolism of your brain, meanwhile, begin to trigger visual and auditory hallucinations.

At 85 degrees, those freezing to death, in a strange, anguished paroxysm, often rip off their clothes. This phenomenon, known as paradoxical undressing, is common enough that urban hypothermia victims are sometimes initially diagnosed as victims of sexual assault. Though researchers are uncertain of the cause, the most logical explanation is that shortly before loss of consciousness, the constricted blood vessels near the body's surface suddenly dilate and produce a sensation of extreme heat against the skin.

All you know is that you're burning. You claw off your shell and pile sweater and fling them away.

But then, in a final moment of clarity, you realize there's no stove, no cabin, no friends. You're lying alone in the bitter cold, naked from the waist up. You grasp your terrible misunderstanding, a whole series of misunderstandings, like a dream ratcheting into wrongness. You've shed your clothes, your car, your oil-heated house in town. Without this ingenious technology you're simply a delicate, tropical organism whose range is restricted to a narrow sunlit band that girds the earth at the equator.

And you've now ventured way beyond it.

Brrrrrrr…..
