If you recall the legend, Rudolph was a bit of an outcast thanks to his bright and shiny red nose. All of the other reindeer might not laugh and call him names if they knew his nose was really the result of an issue with the microvascular flow in his nasal mucosa.

According to the paper, “The exceptional physical burden of flying with a sleigh with Santa Claus as a heavy load could have caused cerebral and bodily hyperthermia, resulting in an overworked nasal cooling mechanism that resembles an overheated cooling radiator in a car: Rudolph suffered from hyperemia of the nasal mucosa (a red nose) under more extreme heat loads during flight with a sleigh.”
