Study: Red Noses Help Reindeers Cope With Polar Air

Rudolph is of course known as the red-nosed reindeer, and scientists say they may know why that’s the case.

Physiologist Dan Milstein with the University of Amsterdam and a group of colleagues examined the noses of several living reindeer.

“There was a much richer amount of blood vessels present inside Rudolph’s or reindeer’s nose in comparison to humans,” Milstein says.
