What should I do if I turn on air conditioning and heating in winter?

When air conditioning is running, doors and windows are usually closed to save electricity, which may be the main reason for lack of oxygen, especially in small and crowded indoor spaces. If the sulfur dioxide exhaled by the human body cannot be discharged indoors in time, it is easy to feel hypoxia, dizziness and chest tightness. Every two hours when the air conditioner is turned on, you have to open the window for a while.

1, because the human body is very sensitive to air temperature and humidity, ventilation can not only dilute harmful gases, but also restore the environment to a certain humidity and gradually restore the self-regulation function of the human body. In a small space (about10m2), it is generally recognized that the best ventilation period is about two hours. If you can breathe 15 minutes in two hours, it is the most environmentally friendly and healthy to keep the indoor air fresh without increasing too much power consumption.

2. The room should be humidified to improve or adjust the dry and wet conditions suitable for people's lives. You can add an ultrasonic humidifier, or drag the floor and ground several times to put more pots of water to evaporate, and create a suitable living environment through manual conditioning.

Extended data:

There are several reasons for this phenomenon:

1. The user has a basic heart and lung disease and is weak, so it is not suitable for living in an air-conditioned environment;

2. Turn on the air conditioner in winter, the room is closed, the air quality is not good, and the oxygen content will also decrease, which makes people feel anoxic-"breathless";

3. It is inevitable that the air conditioner will run for a long time, and it will also affect people's respiratory system. A "dry hygrometer" can be set to monitor the indoor humidity so as to manually adjust the environmental conditions.
