1, keep the proper temperature. The indoor temperature should be controlled between 18-23 degrees, and it must not be too hot. Originally, we did it. The hotter the weather, the more water evaporates, and the difference between indoor temperature and outdoor temperature is large, which makes it easy to catch a cold.

2, suitable humidity, virus bacteria are more likely to reproduce under dry conditions, so keep moisturizing or humidifier, put a basin of water in the bedroom and drag it with a wet mop.

3. Strengthen ventilation. Indoor doors and windows were closed for six hours, and oxygen dropped by 20%. We work 24 hours a day. If the doors and windows are closed, you will be seriously deprived of oxygen. Therefore, it is necessary to open the window in the morning and evening 15 minutes for ventilation. On the one hand, oxygen and fresh air are sufficient, and the density of viruses and bacteria reduces the incidence of diseases.

You can put some flowers and plants in the house to moisten the air, but remember not to put them in the bedroom at night.
