The highest surface temperature of this round in Henan is 74. 1℃. What effects will high temperature weather bring?

It will have a great impact on our health, water quality, crops and so on.

Personally, the hot weather affected my wallet. I'm very afraid of heat. As long as it is hot in summer, I feel like a deflated ball. I don't want to do anything, go out or go to work. I don't want to move on a hot day ~ ~ As a result, I didn't do much work, my income decreased, and my money ~ ~

What is hot weather?

The World Meteorological Organization's standard for high temperature weather is that the daily maximum temperature is higher than 32℃ and lasts for more than 3 days. China's standard is that when the daily maximum temperature reaches or exceeds 35℃, it is called high temperature, and it lasts for several days (more than three days) and is called high temperature heat wave. Generally speaking, there are usually two kinds of high temperature, one is dry heat and high temperature with high temperature and low humidity; The other is hot and humid, which is called "sauna day".

High temperature weather standard

China divides the early warning of high temperature weather into three levels: blue, yellow and orange. However, according to their own characteristics, some provinces and cities continue to use the early warning method of meteorological disasters in 2007, and divide the high temperature early warning signals into three levels, which are represented by yellow, orange and red respectively.

The yellow warning signal indicates that the weather is sultry, generally indicating that the daily maximum temperature will be above 35℃ for three consecutive days;

The orange warning signal indicates that the weather is hot, which generally means that the maximum temperature will rise above 37℃ within 24 hours;

Red warning signal means extremely hot weather, which generally means that the maximum temperature will rise above 40℃ within 24 hours.

The influence of high temperature weather

Hot weather will make you uncomfortable. As the body gets hot, blood vessels will expand. This will lead to lower blood pressure, and the heart will work harder to send blood to the whole body. It can cause slight symptoms such as swollen feet or prickly heat, which is caused by leakage caused by vasodilation. At the same time, sweating can also lead to the loss of body fluids and salt, thus breaking the balance between them, thus causing a series of physical symptoms such as dizziness, nausea, fainting, muscle spasm, excessive sweating and fatigue.

Easy to get heatstroke. Heatstroke is a disorder of body temperature regulation when the heat in the body cannot maintain thermal balance in a high temperature environment. Especially in the "sauna days" with high temperature and humidity, high humidity will hinder perspiration, make it difficult to dissipate heat, lead to heat accumulation in the body, and cannot be adjusted by itself, thus causing heatstroke.

High temperature weather will make a large number of cultivated land, grain and crops short of water, leading to land drought and grain failure, which will greatly affect people's economy. High temperature heat wave may also trigger complex extreme meteorological events, affecting energy, transportation, construction, agriculture, tourism and other aspects.

Under the condition of continuous high temperature, the increase of water temperature will change the physical and chemical properties of water quality, which will have adverse effects on aquatic organisms and aquatic ecosystems, including water circulation, water supply and drainage, industrial and agricultural water, human living water and human health.

What if the weather is hot?

The first is to reduce going out. Avoid exposure to the sun, and you can wear an umbrella or a hat when you go out during the day.

Second, pay attention to diet and eat more foods containing potassium, such as bean products, potatoes, watermelons and bananas.

Third, we must replenish water in time. Drink more boiled water, or drink some light salt water appropriately to supplement the salt in the body.

Fourth, some heatstroke prevention and cooling drugs can be used. Carry with you Huoxiang Zhengqi water, ten drops of water and cool oil. If you encounter heatstroke or discomfort, even if you treat yourself.

In short, pay attention to the hot weather, don't think it's just a little hot. It doesn't matter. Heatstroke can also cause life-threatening, which should not be underestimated.
