The temperature is cold in winter. Personally, I think we should do the following to keep out the cold:

It gets colder every day after autumn, and you should wear more clothes in winter. Don't think about etiquette, don't worry about the temperature, your body is your own, don't ruin it. Besides wearing long trousers, you should also wear sweaters and down jackets. This can be decided according to the local temperature. In the south,

Besides using more clothes to keep warm, we should also start with physical exercise. When you have nothing to do, don't sit there and play mobile phones, games and dramas. You should go outdoors to exercise more. Whether it is running, cycling or ordinary walking, it has a certain effect on the body and can also warm the body.

If you have done the above two points, but you are weak, you can also consider eating more warm food to keep out the cold. For example, you can eat more beef and mutton, yam, jujube, fish soup, hot pot and so on. These ingredients and diet can make your body more effective in keeping out the cold.
