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.

I have a small amount of experience with it.

At 68F, I've swum for two hours. Days when no one else
at the beach would go in the water. The trick is to keep
moving, and if "standing" in the water, to jog on the spot.
That helps balance the heat loss.

At 49F, I could swim about 50 feet along a dock, and barely
had enough limbs left to grab the ladder and get out.
I had a helper on the dock, ready to assist if
necessary. And that's wearing swim trunks.

Go find some videos on the internet called "chillygirls" - there are
naked women (that's women, and I assume from your name you have a pair
of balls so should be braver) in 0C water (that's 9.5C colder than what
you were in) for far longer than it would take you to swim 50 yards.
Funnily enough they needed no help getting out, and thoroughly enjoyed
themselves. On youtube you can find videos of Russians playing chess in
0C water, and even primary school children swimming at 0C.

None of the videos show what temp the water is, so you've no idea what
it is. In fact, apart from the part of the water contacting the ice it's
likely to be between 1-4ºC.

When there's ice in the surface, the water won't be more than half a degree away from freezing. Water conducts heat very well, and it also convects well.

Also none of the videos show people in the
water longer than a couple of minutes. The russians and scandinavians
usually do it after being in a sauna so their bodies are superheated.

Couple of minutes indeed. This is 12 minutes, and he isn't even chattering his teeth:

Why don't you try it before you spout more ****e?
