202 1 Will 2022 be a cold winter year? Not necessarily.
La Nina phenomenon has a very important impact on global weather and climate. In China, there are two main factors in winter. First, the water vapor transport in South China is weakened, and the precipitation in Jiangnan and South China may be less than that in the same period. Influenced by La Nina in the later period, the southern region will have the possibility of drought and sustainable development. Secondly, La Nina, as a tropical SST anomaly, may have a certain forcing effect on the atmospheric circulation in the middle and high latitudes, leading to frequent and strong cold air affecting China.
Contrary to the well-known El Ni? o phenomenon, the so-called La Ni? a phenomenon is considered as an overcorrection phenomenon after El Ni? o. When La Ni? a occurs, the water temperature in the eastern Pacific will drop, which will bring more serious drought to the United States and other regions. In the western Pacific, water temperature will increase and precipitation will increase.
Although this force seems to be less powerful than El Nino, the disaster that La Nina may cause should not be underestimated. For China, La Nina may lead to Leng Xia fever in winter, and more tropical cyclones will land in China. According to the statistics of the past 70 years, there is a 70% chance that China will enter a colder winter in La Nina.
Climate experts point out that if La Nina really happens this year, we should be prepared for the cold winter. Winter in the northern hemisphere may be lower than in previous years, especially in southern China. At the same time, there may be dry weather in some areas, which also requires us to be vigilant.
How to keep warm in winter 1, and improve resistance.
Reason: The cold climate in winter is easy to induce the recurrence or aggravation of chronic diseases. Pay attention to cold and warmth. In order to keep warm, it takes less time to open the window and ventilate, and the air circulation is insufficient, which provides conditions for the reproduction of various bacteria. Secondly, whether indoors or outdoors, the air in winter is not moist enough, and the dry nasal cavity will leave more opportunities for bacteria. Third, the temperature difference between indoor and outdoor is large in winter, so the human body needs more energy to adapt to the change of temperature difference and is more vulnerable to bacterial invasion.
Methods: In particular, it is necessary to prevent the adverse stimulation of strong wind and cold weather to the body and prepare first-aid drugs. At the same time, we should pay attention to cold tolerance exercise, improve cold tolerance and disease resistance, and prevent respiratory diseases.
Step 2 get enough sleep
Reason: Sun Simiao, a famous doctor in the Tang Dynasty, said, "Don't go out early and come back late in winter, which offended Han Wei." . Go to bed early to nourish yang, and get up late to solidify yin essence. As the saying goes: spring is sleepy, autumn is sleepy, summer is sleepy and winter is sleepy, and there are still three months. Chinese medicine pays attention to spring hair, long summer, autumn harvest and winter storage. Winter should be a vibrant season.

3. Cold breeds from the soles of your feet
Reason: There is a folk saying that the soles of the feet are cold. Because the foot is the farthest end of the human body, with thin fat and poor heat preservation ability, Chinese medicine believes that the acupoint on the sole of the foot is closely related to the internal organs. If your feet catch cold, it will cause colds, abdominal pain, low back pain, dysmenorrhea and other diseases, so you should pay attention to keep your feet warm and cold.

4. Open the window for ventilation
Reason: In winter, the doors and windows of bedrooms are generally closed, which leads to insufficient indoor air circulation. People always breathe in this space, which will lead to a lot of carbon dioxide and hypoxia. People will feel dizzy and chest tightness, so they should be ventilated more.
Methods: Open the window 10 minute every morning, noon and evening to keep the indoor air fresh. Experiments show that 60% of harmful gases in indoor air can be removed by each ventilation. In addition, an appropriate indoor temperature must be maintained to avoid excessive temperature difference between indoor and outdoor. The indoor temperature is generally controlled at 16-22℃.
