Does the cold weather and epidemic continue in the distance?
Cold wave is cold air from polar regions or cold zones in winter, which invades the middle and low latitudes on a large scale like tides. When a cold wave strikes, the temperature will drop sharply, accompanied by strong winds, rain and snow. It has a serious impact on industrial and agricultural production, people's lives and human health.
The cold wave invading China mainly broke out in the Arctic, Siberia, Russia and Mongolia. Most of these areas are located in the Arctic. In winter, there is no sunshine for a long time, and there is snow and ice everywhere. The air masses staying in these areas are getting colder and drier. When this cold air mass accumulates to a certain extent and the air pressure increases to a level much higher than that in the south, it is like a flood stored in a mountain. At the first opportunity, it floods to the south with lower air pressure, forming a cold wave.

In times of crisis, the body will release adrenaline. Cold is a stimulus to the body, which can also excite sympathetic nerves and increase the secretion of catecholamines.
Cold can also stimulate the secretion of growth hormone. We see that Europeans are taller. In addition to race, it has something to do with the cold weather in the local area. China northerners are generally taller than southerners, because cold can really stimulate the secretion of growth hormone, so children should not be afraid. Cold can make children grow taller and enhance immunity.
