Do Ice Swimmers Have Bigger Brains?

Researchers found that the brains of newborn seals (Leptonychotes weddellii) are large when they are born. The baby seal's brain size is relatively large compared with adult seals and, remarkably 70% the size of adult brains.

What is remarkable about these seals are that they are the only mammal that swims long distances under the sea ice, holding their breath for up to 20 kilometers until they pop up in breaks in the Antarctic ice. Their big brains help them navigate these marathon distances in the icy cold waters at the bottom of the Earth.

So we thought, are there any implications of brain size and the ability to swim in cold waters among humans?

Does that imply that human ice swimmers also have larger-than-average brains? Do their brains enable them to go long distances in extremely cold waters? There are some sharp cookies among the ice swimming crowd, so perhaps they are born with large(r) brains?

The Other Shore

The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.

2014 Open Water Swimming Almanac

An Almanac for Open Water Swimming

An almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.

This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.

But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.

In fact, there is even one for open water swimming...

The trends are very clear.
The tide is rising for open water swimming.
