Some outdoor workers live in cold areas, and many people think that drinking will increase the heat in our bodies and play a good role in preventing cold. In fact, this method is unreasonable, because drinking will accelerate the blood circulation in our body, and there is an obvious feeling of burning all over the body, which is the role of alcohol. However, after drinking, our body will feel very cold at this time because a lot of heat is emitted to our body, which means it will be even colder after drinking.

Step 2 Wash your face with hot water

When we go home at night in winter, we can wash our face with a basin of hot water and then steam it, which will make us feel very comfortable, because the hot air can relax the pores of our face and promote our microcirculation system. However, we can't wash our face with hot water when we get up in the morning, because the blood vessels in our body contract under the invasion of cold air, and will stretch quickly when we meet hot water. I will go out to work soon after washing my face, so there will be cold air outside.
