shoulders and neck? That’s known as pre-shivering muscle tone. It means your body temperature has hit 97 degrees.’
He began to move more. His legs shook against their bindings, his shoulders trembled, hunched and flexed. He was rubbing himself against the chair, the little that the ties would allow. His feet were shaking and kicking as best they could. His head swaying side to side.
‘Colder now,’ I told him. ‘Perhaps 96 degrees. Your body is shivering so that you generate heat by increasing the chemical reactions required for muscle activity. Amazing but that can actually increase surface heat production by 500 per cent.
‘The bad news is that you can only keep that going for so long because your muscle glucose gets depleted and fatigue kicks in.’
He was shivering so much now that the chair was dancing, shuffling an inch here and there as he did anything he could to get warmer. It was hopeless though.
‘Your hands are especially cold, aren’t they? Your palms will be no more than 60 degrees. Painfully cold. That’s because your body is instinctively sending blood coursing away from your skin, deeper inside you. It is deliberately letting your hands chill to keep the vital organs warm. It won’t be enough though.’
Now he was really shaking, trembling violently. It was almost as if he was having a fit.
‘Your body temperature has dropped to 95 degrees. You have hit mild hypothermia and your body is undergoing its maximum shivering stage. It is contracting your muscles to generate more heat. Don’t worry. It won’t last long.’
I waited and watched and waited some more.
The shivering was violent and broken by pauses. Then the pauses got longer and the shivering shorter.
Before long he had stopped all attempts at movement, no real efforts to move his legs. All he did was shiver. Then eventually, as I knew it would, the shivering stopped too.
‘Oh dear. Heat is draining away fast now. Half of it is disappearing through your head alone. Your ears must be so excruciatingly cold. You are below 95 degrees now. That’s bad. Every one degree drop below 95 means that your cerebral metabolic rate falls off by five per cent. You are losing it. When your body temperature hits 93 degrees then amnesia will start to prey on you. Pity that, I don’t want you to forget anything. Not just yet.’
He just sat slumped in front of me now, occasionally raising his head to look at me with a half-hearted glare. It was the best he could manage. His skin was turning blue. His pupils were dilated.
‘You’re in profound hypothermia now. Your temperature has fallen to 88 degrees and your body can’t be bothered trying to keep itself warm any more. Your blood is thickening. Feel it? Your oxygen intake has fallen by over a quarter. Your kidneys are working overtime. If you hadn’t already pished yourself then you would probably do it anyway. Your body is giving up the ghost.
‘In case you are wondering, and you probably are, there is no specifically defined temperature at which the body perishes from extreme cold. Nazi doctors, those sick bastards that experimented with cold-water immersion baths at Dachau, calculated death at around 77 Fahrenheit. Sometimes it’s lower, sometimes higher.
‘Chilling, isn’t it?’
His chest was heaving. His breathing was severely troubled.
I watched him intently.
‘You will now be about 88 degrees and your heart is in overdrive. Chilled nerve tissues are blocking the heart’s electrical impulses. It is becoming arrhythmic, pumping less than two thirds of the normal amount of blood. There’s less oxygen, your brain is slowing. You might be suffering hallucinations.
‘It’s going to get worse. Two degrees lower and you are going to feel really weird. It’s the strange bit. You are going to feel hot. Really hot. It’s at this stage that people freezing to death feel so hot that they start ripping their clothes off. Sadly that’s not an option open to you. You will just
