"In colder climates and also when they are higher up in the atmosphere pulling Santa's sleigh, the increase in blood flow in the nose will help keep the [nose's] surface warm," said John Cullen of the University of Rochester.

Rudolph's red nose is a popular topic for songs at Christmas time, but what's the real story behind it ?
According to the song, Rudolph's red nose was so red and shiny that it was able to help guide Santa through the blizzards. While the noses of real reindeer aren't quite that luminous, it turns out that the concept isn't quite as far-fetched as it seems. Researchers in the Netherlands have discovered that in cold weather, the nasal mucosa of reindeer draw in blood to help keep the nose warm."In colder climates and also when they are higher up in the atmosphere pulling Santa's sleigh, the increase in blood flow in the nose will help keep the [nose's] surface warm," said John Cullen of the University of Rochester.
The study looked at the deer's nasal circulation and found similarities to the microvasculature in the region with that of humans.
