Ear frostbite

The reason that the ear is most prone to frostbite is closely related to the structure of the ear. Because the entire auricle has adipose tissue in the earlobe to keep warm, the rest has only thin skin that wraps with cartilage, and the blood vessels inside are very fine, so the heat preservation ability is very poor. Especially in winter, the ears are stimulated by cold weather, the blood supply of blood vessels in the ears will be less than other parts, the blood circulation at the end will be impaired, and the qi and blood will not run smoothly, which will cause frostbite.
