1, wash your nose with cold water.

Nowadays, many people like to wash their faces with hot water first and then with cold water. In fact, this is not correct. When we usually wash our face, if we wash our nose with cold water, we will cool our nose first, but let the nasal cavity feel adapted to the lower temperature, so that it is not so easy to catch a cold in spring.

2. Wash your throat with salt water

Many people will have sneezing, runny nose, dry throat and other epidemic symptoms in spring, so we can gargle with light salt water every morning and evening, which can not only help you kill pathogenic bacteria in your mouth, but also prevent spring diseases and stomatitis.

3. Open the window for air.

Because spring is a season with high humidity, keeping indoor air circulation and fresh air is a good way to prevent colds. But when opening the window, you can't stand directly on the window and blow directly.
