Meteorology in China generally refers to the high temperature when the maximum daily temperature reaches or exceeds 35℃. Hot weather will make people feel uncomfortable, reduce work efficiency and increase the incidence of heatstroke, intestinal diseases and cardiovascular and cerebrovascular diseases. At the same time, high temperature weather will also have a greater impact on agricultural production.

Matters needing attention when working at high temperature:

When working at high temperature, a series of physiological function changes will occur in human body. These changes are adaptive responses within a certain range, but if they exceed the range, they will have adverse effects and even cause lesions.

From the point of view of prevention, it is very necessary to do a good job of physical examination for high temperature workers before employment and in summer. Those who have high temperature contraindications such as cardiovascular diseases, central nervous system diseases and digestive system diseases are generally not suitable for high temperature operation and should be given corresponding prevention and treatment.

Provide refreshing drinks, cooling products and supplementary nutrition for heatstroke prevention and cooling: Salt soda, mung bean soup, soybean milk and sour plum soup should be selected for high-temperature drinks, and the drinking method should be small and multiple times. Towels, essential balm, Huoxiang Zhengqi water, Ren Dan and other heatstroke prevention and cooling products can be prepared. In addition, to establish a reasonable dietary system, protein and calories, vitamins A, B 1, B2, C and calcium should be supplemented in the diet.
