I have had mild hypothermia (on a mountain bike race when I was a teenager) During this I'd describe the symptoms as flu like. I was quickly whisked down the mountain by mountain rescue to warm up and suffered no long/medium term ill affects.

I've never had "proper" hypothermia though (thank god) but I've read several books where the writer has suffered this, one of the best accounts I can think of is K2: Life and Death on the World's Most Dangerous Mountain. The books an account of the 2008 K2 disaster of which the writer was a survivor.

Hypothermia itself means that your core body temperature drops below the standard 35C. Hypothermia itself is a scale not an illness, so obviously there is a degree of scale between a 0.5 degree and a 2 degree drop of temperature.

Mild hypothermia is typically not overly dangerous in a healthy subject. The symptoms are vague and vary person to person. Most people who are described as hypothermic have mild hypothermia.

Past this point and into moderate hypothermia the bodies first reaction is to try and heat the core. So you shiver uncontrollably as your body attempts to produce heat though muscle usage.

As the hypothermia becomes more severe though your bodies nervous system starts to become affected. Once you stop shivering you're in this phase. Typically this means the hypothermic person(s) become increasingly groggy, confused and irrational. There's even a condition called paradoxical undressing where the hypothermic person thinks they're hot and removes all their clothes. Your heart rate, breathing rate and subsequently the amount of oxygen in your blood will decrease.

At some point past this your blood pressure will drop to the point where you become unconscious.

Below 30C your bodies cell's essentially cease to function, metabolic rate stops, and the cells begin to die. If this happens in your core your essential organs (heart, liver, lungs, etc) begin to shut down. By this point you will likely be unconscious and unaware of what's going on.

Death is typically caused by cardiac arrest. The heart (for multiple reasons) simply stops.

How unpleasant is it

Very.... It (potentially depending on circumstances) takes a long time with increasingly severe pain/symptoms until eventually you become delirious (you could argue by this point your probably don't care but you will of been in pain for a long time before that point) pass out and then have a heart attack...
