Looking to make a good impression with the big guy in red? It might behoove you to learn a little bit more about life at the North Pole to best understand how to get in Santa Claus's good graces, said Oklahoma Medical Research Foundation scientist Hal Scofield, M.D.
Why does Santa crave milk and cookies? Well, the easiest explanation is that milk and cookies are delicious. But it might also be that grocery shopping is difficult to do in that isolated region. It's about 1,200 miles to the nearest city, so he can't just pop out to the store for Oreos whenever he feels like it.
That said, Santa probably gets reindeer milk fairly regularly … with a little help. Reindeer milk has a fat content of 22 percent, which is six times as much as in cow's milk. But he needs Mrs. Claus or one of the elves to lend a hand, since it takes two people to milk a reindeer — one to do the milking and the other to hold the reindeer's antlers!
“All that extra fat is necessary to keep warm, which may be why Santa stays so zaftig,” Scofield said. In addition to his heavy red coat, Santa has a layer of fat — much like polar bears do — as an additional protection from the cold.
How cold is it at the North Pole? The average temperature in the winter is -29 degrees Fahrenheit. Even during the summer, the North Pole doesn't get much above 32s degree — the same temperature at which water freezes.
Scofield said everybody at the North Pole is in danger of cold-related conditions, including frostbite. Did you know that shivering isn't just an involuntary reaction to the chill? It's activating muscles and creating heat.
“There's a reason everybody on those expeditions to the Arctic Circle are covered head-to-toe,” he said. “The cold weather is dangerous and it's only magnified when it's wet and windy.”
When exposed to those temperatures, the body takes precautions to ensure life continues, even at the expense of extremities — including fingers and toes, he said. Blood is drawn to the heart and brain (both vital for life) and away from hands and feet, which is why they seem to get colder so much faster than the rest of the body.
