Researchers say that Rudolph the Red-Nosed Reindeer really did have a shiny red nose.

LiveScience.com reports that the secret to the signature glowing nose is a dense network of blood vessels.

Scientists say that reindeer have 25 percent more capillaries carrying red, oxygen-rich blood in their nasal architecture than humans.

“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,” Dr. John Cullen of the University of Rochester told MedPage Today.

Researchers compared a couple of reindeer to two humans and found during the study that reindeer noses do turn a rosy red.
