Researchers in Sweden used thermal imaging cameras to learn about the heat flow from reindeer when they ate. They found that, while most of these animals' bodies were well protected by their fur, their noses would glow bright orange in the resulting pictures due to the large amount of heat emitted from them.

The phenomenon is due to reindeer having a high concentration of blood vessels in the nose and lips to keep them warm and increase their susceptibility when scouring in the snow to find food. Only in the nose position, the number of blood vessels of reindeer is 25% of the blood vessels of people.

According to Professor Ronald Kröger, a biologist from Lund University (Sweden), in some cases, this led to the reindeer's nose becoming flushed in cold weather.

Kröger explains further: "When reindeer searches for food in the snow, their noses are exposed to very low temperatures. They need to maintain sensitivity to know what they really are eating. They pump hot blood. The nose, which means the nose will be slightly red due to the large amount of blood rushing in. Thermal cameras show the heat coming from their bodies, in which the eyes and nose area are brighter and warmer than the rest of the body ".

Discovered above revealed, Santa's red-nosed reindeer can exist in real life. The story of Rudolph's reindeer with an unusual red nose stems from a 1939 book by Robert L May and is later portrayed in hundreds of stories, songs and movies about Santa and the sled. snow by his reindeer reindeer.
