Hot and hot!High -temperature weather is here, please check this prevention of heatstroke guidelines

Recently, the Central Meteorological Observatory issued high -temperature warnings for more than 10 consecutive days. The maximum temperatures in Sichuan, Shanghai, Zhejiang, Jiangsu, Henan, Hebei and other places exceeded 40 ° C. Since June, high -temperature incidents have lasted for 30 days, covering an area of more than 5 million square kilometers in my country, affecting the population of more than 900 million people.

A total of 238 national meteorological stations in Hebei, Henan, Tianjin, Yunnan, Sichuan, Zhejiang, Xinjiang and other places exceeded the maximum temperature of the national meteorological station. The maximum temperature of 71 national meteorological stations exceeded the historical extreme value.

On July 14, the spray device was opened in Shanghai Yuyuan Mall for heatstroke prevention. On the same day, the Shanghai Central Meteorological Observatory issued the third high -temperature red warning signal this year, with a maximum temperature of more than 40 degrees Celsius.

The monitoring data of the National Climate Center shows that since June this year (as of July 12), the average number of high temperature days in my country is 5.3 days, the most historical time since 1961, and the comprehensive intensity has been the 6th since 1961.

The National Climate Center analyzed that since the 21st century, the typical year of a large -scale continuous high temperature event in my country includes 2003, 2013, 2017, etc. Generally speaking, this year's high temperature incidents began to be as early as the above three years, and the highest temperature and the highest temperature of the single station had exceeded 2003 and 2013.

Why is it so hot this summer?

According to the monitoring of the National Climate Center, in June of this year, the global average temperature was about 0.4 ° C higher than the usual year, the highest since 1979. The sixth evaluation report of the Special Committee for Climate Change of the United Nations (IPCC) pointed out that global warming in the past 50 years has occurred at unprecedented speeds in the past 2000, and the unstable climate system has intensified. The National Climate Center pointed out that global warming is a frequent climate background of the high -temperature heat wave incident in the northern hemisphere, and the abnormal atmospheric circulation is the direct cause of frequent high -temperature heat waves in many places in the world since June.

According to Yuan Yuan, the chief of the National Climate Center Dating Dating, since June, over the subtropical region of the northern hemisphere, the Western Pacific subtropical high -voltage (referred to as the auxiliary high) belt, the Atlantic high -voltage belt, and Iran's high -voltage average increasing increase, which has formed a large -scale global global worldwide Warm and high -pressure band. Under the control of warm and high voltage bands, the prevalence of sinking air is conducive to the heating of the ground. In addition, under the action of a large -scale high -voltage belt, the air is dry and the cloud is not easy to form. , And strong intensity, which causes high temperature heat waves in the northern hemisphere.

Specific to my country, the continuous La Nina incident has provided an important climate background condition for the development of high temperature in the south since June this year. According to statistical analysis, in the summer of most La Nina incidents, the deputy high is easy to north. Since late June, the deputy high north, especially the typhoon "Siaba" in early July, has strengthened the west extension, Iran's high pressure east, and combined with the high pressure of the mid -latitude continent to form a stable. Warm high -voltage belt, which causes a large range of high temperature weather. In addition, due to the water vapor carried by the vice -high high, the humidity of the central and eastern regions of my country makes the somatosensory temperature higher.

The sun is like a fire, a hot summer. When children enjoy a happy holiday, parents must pay attention to their children's safety protection. The following knowledge of heatstroke prevention should be collected!

What is heat stroke

Severing heat stroke is a series of pathological symptoms based on neurological and circulating dysfunction in the environment where high temperature and high fever and air are not circulating.

Reasons for heat stroke

Environmental reasons: increased atmospheric temperature (greater than 32 ° C) and (or) greater humidity (greater than 60%), and no air environment.

health issues:

1. The ability of the human body to adapt to heat decreases, and the body's heat production increases.

2. Long -term labor or physical activity in summer, insufficient heatstroke and cooling measures.

3. Human body heat dissipation disorders: wear tight and impermeable clothes, the elderly, weakness, obesity, dehydration, insufficient sleep, diabetes, hyperthyroidism, water and soil dissatisfaction, applied atropine and anticholine drugs, etc., can become heat stroke in summer Cause.

Children should be vigilant

① Children will have some threatened symptoms before heat stroke, such as: skin rash, which is the tweezers we often call; dizziness, chest tightness, nausea and vomiting, and sore limb muscles ... If it is not treated in time, it may lead to heat stroke!

② Light heat stroke: Children will have dizziness, headache, redness, thirst, sweating, general weakness, palpitations, fast pulse, inattention, and uncoordinated movements.

③ Severe heat stroke: Including heat spasm, heat failure, and thermal radiation disease, most of them are accompanied by symptoms of significant increase in body temperature.

Different heatstroke conditions can be handled like this

① Hot rash, also known as mule, is a skin irritation caused by sweating a lot in hot and humid weather. It can happen at any age, but it is common in children. This rash can disappear shortly after the skin is cool.

How to identify:

The mule looks like a red pimple, often appearing on the neck, upper chest, groin, and elbow folding.

How to deal with:

The best way to treat heat rash is to provide a cool, humid environment to keep the affected area dry. The treatment of heat rashes is very simple, and usually does not need to go to the hospital for professional rescue. ② sunburn. People should try to avoid sunburn. Although the discomfort caused by sunburn is usually mild, it can usually be relieved after a week, but it is still a kind of damage to the skin. Severe sunburn needs to be treated at the hospital for treatment.

How to identify:

The skin becomes red and feels pain, and the temperature rises abnormally after the sun.

How to deal with:

If you are less than 1 years old or have symptoms of fever, blisters, or severe pain, you should consult a professional doctor.

When dealing with sunburn skin, remember the following points:

Avoid repeated sun exposure.

Please apply cold compresses or soak in cold water.

Apply moisturizing lotion in the sunburn, do not use cream, ointment and other skin care products with too thick texture.

Don't squeeze the blisters.

③ heat spasm. When people do severe exercise and sweat a lot, the salt and moisture in the body are lost together with sweat. Low salt content in the muscles may be the cause of thermal cramps. In addition, heat spasm may also be a manifestation of heat failure.

How to identify:

The painful spasm of large muscle groups such as limbs, abdomen, and body temperature may rise, generally not exceeding 40 ° C.

How to deal with:

Moved to a cool and ventilated place, while replenishing the liquid, giving muscle stretching and massage.
