What is the most important thing to do in the light snow solar term?

Light snow and solar terms are the best ways to prevent colds.

The arrival of the "light snow" solar term means that the snowfall in winter officially kicks off, and it is also the time when you are most likely to catch a cold.

The first is that the temperature is too low. When cold air suddenly attacks, people's nasal mucosa is stimulated, and their ability to resist the invasion of external germs is reduced; Cold air can also promote the activity of germs.

The second is the dry climate. People suffering from chronic respiratory diseases, if the air humidity is too low, will easily cause phlegm to be sticky or form dry scabs, which will not only make the stored sputum a breeding ground for viruses and bacteria, but also fix the sputum forming dry scabs on the bronchial mucosa epithelium, so that the cilia at the top of the mucosa can not rely on normal movement to help discharge sputum, thus further destroying the physiological function of mucosal cilia.

In addition, the indoor ventilation is poor. In winter, most people don't often open windows for ventilation. Indoor pollution is dozens of times that of outdoor pollution in winter, which has a great impact on respiratory health.
