What are the measures to prevent cold and keep warm when Shanghai is frozen into Aisha Castle after a cold wave overnight?

Recently, after a night of cold wave, a rare winter beauty appeared on the Dianshan Lake in Shanghai, which is not frozen all the year round. Some netizens said that Shanghai was frozen into Aisha Castle.

Before this winter came, it was already online. What will happen this winter? The coldest winter? Rumors. However, I have never felt the difference between this winter and previous years, or even felt that it came later than previous years, and everyone didn't put it in front? The coldest winter? The rumor is very serious. It was not until the end of1February that people really felt the cold of this winter. In addition to the local temperature drop of more than ten degrees, warnings of cold waves and strong winds were issued in many places, and the temperature also hit a new low since winter, and some areas also broke the record of the lowest temperature in previous years. It can be seen that the power of this cold wave cannot be underestimated. Netizens from all over the world have also exposed the lowest temperatures in various places, complaining about how it is so cold this winter. Some netizens even said that the weather was so cold that their doors were frozen. What is the difference between this cold wave and the past? Why is the impact of this cold wave so great? So cold?

It turns out that the main reason why this cold wave is so cold is that it comes from the North Pole? Delivery? Yes Because of its high latitude, the Arctic has no sunshine all the year round in winter and is the cold source of the atmosphere. A large amount of cold air has gathered in the Arctic, forming a large vortex system, which is the main source of cold air in China this time. Another important reason why it is so cold this time is that two cold waves have come one after another. The interval between two cold waves is very short. The low temperature brought by the previous cold wave has not dissipated, and another cold wave has followed, bringing strong winds, rain and snow. Coupled with the previous low temperature situation, it can be said that it is freezing.

In the face of such a low temperature, everyone must take out all the warm measures at home. First of all, we should add clothes in time, and pay special attention to the warmth of feet and hands to avoid frostbite. Secondly, in the face of the windy weather accompanied by the cold wave, try not to go out when you have to, and at the same time strengthen the doors and windows at home. If the window is airy, you can put a layer of plastic cloth outside (to be honest, this is the case in my house, because it is too cold), and you should also tidy up your belongings to avoid being swept away by the strong wind and protect the vehicles. If you are a crowd going out, put on more clothes if you can, keep out the cold in an all-round way, and just watch the road with your eyes open. At the same time, you can prepare more warm stickers and carry hand warmers, thermos cups and other items with you. Finally, pay more attention to the elderly, the weak and the sick. These people are relatively sensitive to temperature and should be taken care of.

Warm reminder, you can put aside your handsomeness and beauty. Keeping warm this winter is the most important thing.
