There's a couple of people with the physiological capability and the necessary mindset (combining derring-do, ability to handle pain, courage, and a dash of nuttiness) to swim in extremely cold (life-threatening cold) water.
Most recently, Lewis Gordon Pugh swam in a glacial lake in the shadow of Mount Everest, taking it slow due to the altitude:

Pugh is a physiological freak: his body heats up when he just thinks about swimming in cold water. Because of this, he has also swum a mile in Antarctic waters, immersed for 30 minutes, and a mile in Arctic waters off Spitzbergen, immersed for 21 minutes.

The other swimmer who has done a couple of these is Lynne Cox, who swam from the United States to Russia in the Bering Sea (between the Diomede Islands) and also a mile in Antarctica. In the Bering Sea, she was in the water about 2 hours, covering 2.7 miles. You can't swim fast in water that cold.

It should also be noted that both Pugh and Cox have done more conventional long-distance swims. Cox was the first person to swim the Straits of Magellan in Chile, and she has also been an English Channel record holder -- twice. Pugh has also done a Channel crossing.
