How high is the temperature in the car in summer when children are suffocated in the car of kindergarten?
4hw.org: it's hot in summer, especially in the car. When the car is exposed to the sun, the temperature inside the car is more than twice as high as the outside. Recently, a tragedy happened in a kindergarten in Xiong county. A child was forgotten in the school bus, and the child was suffocated by the high temperature air. Let's have a look at the details!
On the afternoon of June 28, a human tragedy happened in a kindergarten in Xiongxian county. A child was left in the school bus and was not found until after school. Finally, the child was sent to the hospital for rescue and died.
It is understood that the child is from Yuanzhuang village, Xiongxian county. On the morning of June 28, he took the minibus used by the kindergarten for transfer to go to the kindergarten. When he got off, he was left in the car. It was only after school that afternoon that the child was found still in the car.

Previously, on July 11, 2016, a 3-year-old boy died in the car of the "little angel" kindergarten in Dahe Town, Rongcheng County, adjacent to Xiongxian county.
When the closed environment temperature is higher than 38 ℃, the human body will be uncomfortable
It can be seen from the experiment that under the high temperature weather in summer, the temperature in the closed car will gradually increase with the parking time. Can the human body bear such high temperature?
During the experiment, when the car was parked in the open parking lot for 20 minutes, the temperature in the car exceeded 40 ℃, a stream of hot gas rushed out when the reporter opened the door, at this time, the thermometer placed in the car had been baked hot. The reporter sat in the car and closed all the doors. The window left a gap of palm width. Only ten minutes later, the reporter's head was covered with sweat beads, and there were dry mouth and rapid heartbeat symptoms. After another 5 minutes, the reporter's sweating was obviously reduced, but the whole person felt dizzy and nauseous, so the experiment stopped.
In response, some doctors said that people's body temperature is generally around 36 ℃. When the ambient temperature reaches 32 ℃, the human body will sweat and sweat to cool itself. If the environment temperature is too high and the ventilation is not good, the high temperature in the human body can not be released, it will cause 'heat radiation disease' or heat spasm.
The doctor said that when the temperature reaches 38 ℃, multiple organs of the human body will participate in the cooling activities. At this time, it is difficult to keep the normal body temperature by sweating. The lungs will breathe out heat in a short time, and the heart rate will speed up. 60% more blood will be output to the body surface than usual to participate in the cooling. At this time, people with weak constitution may have heatstroke.
When the temperature reaches 39 ℃, the sweat gland system of human body will be on the verge of failure, sudden heart disease, heart failure and other dangerous situations will occur at any time. When the temperature reaches 40 ℃, the regulating function of brain will start to be paralyzed, resulting in dizziness, standing instability and other phenomena. At this time, you must immediately turn to a cool place or use better cooling measures to cool down.
When the temperature reaches 41 ℃ ~ 42 ℃, it is the maximum limit for human body to bear. If the temperature is kept for a long time, human life will be seriously threatened. All organs and metabolic systems such as perspiration, respiration, blood circulation, etc. of human body may be lost, and people with poor constitution can have accidents at any time.
For children, in a hot vehicle, 20 minutes will cause brain and kidney damage, when the temperature reaches 42 ℃, the child will die.
