A cow in Guangdong was frozen to death alive. Why is it so cold in Heilongjiang, and all the cows are alive and well?

Because the weather in Heilongjiang is very cold every winter, cows are used to it.

A cow in Guangdong was frozen to death alive. How did this happen? As we all know, the weather this year is very special. Phenomenologically, the great cooling in Guangdong is caused by the continuous invasion of strong cold air in the north. The thickness of snow and ice in the north this year is deeper than in previous years. During the Lantern Festival, there was a phenomenon of MINUS 33 degrees in Hebei. It is precisely because the climate in northern China is extremely cold and influenced by strong cold air that the climate in southern Guangdong is further affected. Our country is located in the north temperate zone, and it makes sense that it belongs to warm spring at this time of last year. It is snowing in many places in the south now. Especially in Guangxi, Guangdong and Nanhai in the south, affected by the strong cold air mass in the north, it snows in many places. It is really strange that cattle in Guangdong are frozen to death in today's society. But if we start from the local climate in Guangdong, we can also see that animals may indeed freeze to death. Mainly because the weather in the south has always been warmer, ordinary animals are used to this temperature, and their bodies also have such basic immunity. As soon as the extremely cold weather comes, cows can't adapt to this change quickly.

How does low temperature cause death? In fact, there is also a process of hypothermia death. People's body temperature is generally maintained at around 36.3 degrees Celsius. When the temperature around us begins to drop, our body temperature will also change slightly. At this time, the body will quickly release heat to maintain the original body temperature and once ensure the normal operation of the body. When the body temperature is between 35 and 30 degrees Celsius, in order to maintain the normal operation of the brain, the body begins to gradually weaken its activity, blood pressure begins to drop, blood flow slows down, and the whole person feels very sleepy and eventually dies.

How to avoid this situation? Cows can keep out the cold, but not the wind. Anyone who has used real cowhide knows that cowhide is a very breathable material. Although it can play a good role in keeping warm, if there is no windproof design, wearing a cowhide coat will be very cold. After all, cowhide is too breathable, which is the fundamental reason why cows need to keep warm when they sleep at night. Finally, in winter, we must pay attention to repairing the cowshed, repairing the air leakage and laying a layer of hay for the cows.
