Why are there more receptors in human skin that are sensitive to cold than heat? Why are most of them on the lips and face?

Under natural conditions, a person does not often come into contact with such a high temperature as to cause burns, and in the case of a cold winter, low temperatures can cause frostbite or stimulate inflammatory diseases, therefore there are more receptors that are sensitive to cold, as to a more dangerous factor. At the same time, the face remains open in the cold season, so there are more receptor endings.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
