That's the Polar Bear Club swim. (There are several cities
that conduct these events.) It's a kind of idiocy test.
And no, they don't throw you in. You have to enter on your
own. And volunteering to enter, is the "personality test".
Getting out is easy. These are generally done in shallow
water, so someone in a dry suit can pull you out if needed.
The fire departments here, are equipped to extricate fools
from cold water :-) (Zodiac, boat trailer, dry suits, there's
such a setup only a ten minute drive from me, ready to go.
Call 911 if you need help.)

Are you serious? 10 seconds? Water is never cold enough to get out
that quickly. I can swim in zero degrees C water for a couple of
hours. Humans are warm blooded. Shivering doesn't mean you're going to
die, it means you've lost 1 or 2C (out of 17C required to die) and your
body is shivering to prevent further heat loss, not to mention brown fat
cells generating heat, and of course limiting heat loss by adjusting
blood flow to the skin.
You're either exaggerating,
Nope, I'll make some videos next time we get wintry weather here in Scotland. I've just bought an HD video camera.
swim with a dry suit
Dry suits are for girls.
or actually a whale (or
have the blubber of one).
Fat people get colder, they don't have the metabolic rate to generate so much heat.
In winter weather people die in around 30
minutes when submerged in cold (10ºC) water.
The official bull**** is actually 15 minutes at 0C, 30 minutes at 5C, and a whole hour at 10C.
Hyper
Hypo, dimwit.
thermia kicks in when the core temp drops below 35ºC.
Wrong wrong wrong. You die at 20C.
Below 30ºC
you're unlikely to be conscious. At 20ºC you're long dead (except in
exceptional circumstances!).
