Young foreigners are afraid of cold and heat.

The reason for being afraid of cold and heat is that high fever will be caused when the sun rises.

According to the website of Yue Health 360, Yang can cause high fever, and fever is afraid of cold and heat. Fever, fear of cold and fear of heat belong to two different stages of fever. In the early stage of fever, patients will be afraid of cold, mainly because their body temperature is rising, and when the patient's body temperature rises to a certain extent, patients will be afraid of heat. This is because the body has begun to dissipate heat, mainly through sweating, which can gradually reduce the body temperature.

Little foreigner originally refers to lively people, but in today's epidemic, it refers to people who are infected with COVID-19 virus and tested positive for nucleic acid.
