High temperature and cold knowledge 丨 40 ° C is here your "temperature control center" is okay?

Zhejiang News Client reporter Chen Ning Zheng Wen

hot! hot! hot! The weekend just passed, Zhejiang's geothermal geothermal exudes a new height in history.

When the high temperature of 40 ° C "comes", how should the human body adjust? From today, some doctors say that the medicine focuses on "high temperature and cold knowledge" and talks with you about health -related things--

do you know? Faced with high temperature, the human body has a natural "barrier". Scientific research shows that the average temperature of the human body is about 37 ° C, and there are about 2 million to 5 million sweat glands on the human skin. They are "natural air -conditioners" and shoulders the heavy responsibility of regulating body temperature.

In summer, when the temperature of the outside world rises above 30 ° C, the human "temperature control center" will issue an alert depending on the external temperature. For example, the temperature of the first -level alarm is 36 ° C. In this temperature, the human body will heat dissipation by evaporating sweats to perform "self -cooling"; once the temperature rises to 38 ° C, it is the temperature of the second -level alarm. Normal body temperature, not only does the lungs say that the calories are exhaled, but even the heart must be accelerated; 39 ° C is a three -level alarm temperature. Sweat glands are not capable of working, no longer ability and failure ...

Medically, thermal radiation disease that has received more attention in recent years also belongs to the schedule of heat stroke, called severe heat stroke. In other words, the human "temperature control center" issued a strong alarm.

Zhang Mao, deputy dean of the Second Hospital of Zhejiang University, "knocked on the blackboard" to Youyi Jun. After seeing the heat of thermal radiation, it is especially important to learn high temperature self -rescue.

"Whether it is light heat stroke or severe heat stroke, we must first leave from high temperature environments and enter a relatively cool environment such as air -conditioned rooms." Zhang Mao said that if it is a light heat stroke, some liquid should be appropriately supplemented by some liquids. Of course, the simplest thing is to drink boiled water. When you sweat a lot, you need to drink some sugar and saline. If you cannot judge the symptoms of heat stroke, call the professional first -aid personnel as soon as possible to the hospital for treatment.

So, how should some outdoor workers who have to face the scorching sun be avoided by high temperatures? Zhang Mao suggested that trying to avoid working at the sun at the sun, and at the same time to reduce the time of continuous work, more importantly to replenish sufficient water in time.

Many emergency experts suggested to the medical monarch that high temperatures "strike", everyone should get some first aid knowledge. For example, once there are heat stroke around the surrounding people, the patient should be moved to the cool place and keeps ventilation; take off the mask, unbutton the buckle, and use multiple methods to help the body heat dissipate; appropriately take Huoxiang Zhengqi and other heatstrokes, and try pressing press Human acupoints and other methods help resume consciousness. If the symptoms are not reduced, the rescue call should be called immediately.

[Cool more every day]

Before the invention of the fan and air conditioner, humans defeated the heat with wisdom.

In the Spring and Autumn Period, people have understood how to collect ice cubes to accumulate winter. In the "Book of Songs" and "Zuo Zhuan", there are records of hidden ice in winter. At that time, there were "Ling people" hiding collection of ice cubes. Ice cubes were chilled every year in the winter. Wait for "ice room" and "ice well".

In the Tang Dynasty, there were more and more ways to prevent heatstroke and cooling. At that time, there was a wooden appliance that can be diversified and the house was sprayed with cold water to cool down. In "Tang Yulin", a "Liang Temple" built in the palace of Tang Xuanzong was built in the palace. The equipment that used the water -diverted house was "four stums of water, and the curtains were sprinkled". The fan was also installed in the palace.

After the Tang Dynasty, cold drinks became a fashion. Du Fu, a poet of the Tang Dynasty, wrote a poem "Grand Son adjustment of ice water, beautiful beauty snow ravioli". Yang Wanli, a poet in the Southern Song Dynasty, praised a cold drink called "ice cheese".
