Why are some people afraid of the cold and some people not afraid of the cold in winter?

There is a limit to everything. Physiologists warn that no matter how strong a person is, he can't live without clothes at MINUS 40 degrees Celsius for 15 minutes.

In the 1980s, a scientific seminar was held in London to study how long people who fell into the water at sea could live. Scientists' research results show that when the water temperature is zero, people can tolerate 15 minutes; At 5 degrees, you can stand 1 day and night. No wonder the little match girl in Andersen's fairy tale froze to death on Christmas Eve.

Surprisingly, there are very few people in the world who are not afraid of cold.

On the streets of Trieste, a coastal city in Italy, people reported to the patrolling police one after another that there was a little boy wearing only swimming shorts, carrying a schoolbag and going to school in the biting cold wind every day. He must have been abused by his parents.

The police were also very angry and stopped the 8-year-old boy.

"Tell me, son, if your parents don't give you clothes!"

"No, officer."

"Poor child, don't be afraid. This is a crime, and we are here to see you. " The police are getting more and more angry.

"Sir, you listen to me, not my parents don't dress me. It's that I'm not afraid of the cold since I was a child. I only wear these swimming shorts and slippers. I must be naked. "

"Is that really the case? Did your parents take you to the hospital for examination? " The policeman asked the little boy with concern.

"Many big hospitals have been there, and doctors don't know what's going on."

"Son, hurry home, how cold it is."

Looking at the child's unafraid back, the policeman shrugged inexplicably.

In fact, there are children who are not afraid of cold in cold weather in China.

There is a little boy in the suburb of Nanjing. He was born not afraid of the cold. He wears no clothes all the year round. Even in snowy weather, he still plays outside naked and has never caught a cold.

1979 In August, a little girl named "Huowa" was born in the suburb of Mianyang, Sichuan. She likes cold and hates heat, and she doesn't wear clothes in cold weather. If cold water is poured on her, it will be like nothing. Even if she sleeps in winter, she never covers herself, but only sleeps on straw mats. If you dress "Huowa" with a quilt, she will get sick with a fever.

In Anyi County, Jiangxi Province, there is also a girl named Xia who is not afraid of cold. When the temperature is MINUS 3 degrees, she only wears a single coat, a pair of rubber shoes and no socks. Her father told the visiting reporter that her daughter didn't like to wear clothes when she was born, and she cried as soon as she was dressed. I wanted to dress her before I was two years old, and then I managed to wear a thin coat, and then I didn't add any clothes.
