If the temperature drops again, it will be even worse.

On the other hand, because they are strong, these two cold waves are part of the main body of the polar vortex heading south. They pass by the cold air "gas station" in Siberia and accumulate more energy, which increases the temperature of the cold air mass. Lower, stronger cooling ability.

Why do many people feel so cold?

Remind everyone that you must keep warm in this cold weather and do not stay outdoors for a long time to avoid frostbite. So what parts should we do to keep warm when we go out in winter?

1. Neck

The neck plays the role of connecting the upper and lower parts. Once caught cold, local blood vessels will constrict, reduce the blood circulation speed, cause dizziness and insufficient blood supply to the brain. Therefore, you should wear a warm scarf when you go out in winter to resist the invasion of wind and cold and prevent colds.

2. Abdomen

There are many important acupuncture points in the abdomen, which are susceptible to wind and cold, which can lead to abdominal pain. Cold in women's abdomen can easily cause dysmenorrhea, cold hands and feet, and irregular menstruation. Cold in the male abdomen can lead to prostate disease or sexual dysfunction. You can’t eat raw or cold foods in winter. You might as well eat more qi- and blood-enhancing foods such as mutton, dog meat, longan, yam, or red dates. You can also apply a hot water bottle to your abdomen.

3. Feet

As the saying goes, cold air originates from the feet. When the temperature drops, it will also slow down the blood circulation throughout the body, so that the peripheral parts do not get enough blood nourishment, which in turn causes the feet to Ice cold. Therefore, keep your shoes and socks warm and dry, and stand up and move for 10 minutes every hour you sit to promote blood circulation in your feet.

In this cold moment, you should not only rely on demeanor but not temperature to avoid frostbite on your skin. Every night before going to bed, you can soak your feet in hot water and massage the soles of your feet at the same time, which can achieve health care effects and warm the whole body.
