Is it true that winter is extremely cold?

Winter is expected to be cold, so it will be especially cold;
-The winter of 2022 is expected to be a cold winter, mainly because this year may be a "La Niña year". The so-called La Niña year means that the probability of colder winters in the south is higher than in the north, which will make extreme cold weather very likely to occur. When in a La Niña state, the sea temperature in the equatorial eastern Pacific region is 0.5° lower than usual. This phenomenon has a very obvious impact on China's climate. Under the influence of La Niña, the meridional circulation in East Asia is abnormal. Such a circulation situation is very conducive to the southward movement of cold air from northern China. It causes us to have a cold winter, so we can see that this cold winter has arrived.

Tips on keeping warm in winter

1. The room should be ventilated , because an environment with poor air circulation can cause problems in the body. In severe cases, it may cause difficulty breathing and lesions in lung function.
2. Soak your feet in winter . In winter, you must take measures to keep your feet warm, because the cold air can easily enter our body through our feet. At this time, you can soak your feet to keep your feet warm. At the same time, in addition to soaking your feet, you can also put some heating pads on the insoles to keep your feet warm.

In winter, if you want to increase body temperature, blood circulation must be accelerated, and the associated factor of blood is iron. Iron deficiency in the blood can easily lead to coldness, anemia and other phenomena.
4. Don’t do morning exercises too early . Now with the rapid improvement of living standards, many middle-aged and elderly people like to do morning exercises in the morning. Even though it is said that exercise can make people live longer, we still have to distinguish the temperatures of the four seasons before exercising. The temperature in winter is relatively low, and the temperature in the morning is very low, which can easily cause a cold.
5. All-round warmth . Keeping warm in winter is a long process. You should have all the necessary warming supplies, such as hot packs, heating pads, air conditioners, electric heaters, outer cold-resistant clothing, socks, gloves, hats, scarves and quilts on the bed, etc. It is recommended that you wear high-top warm shoes.
