Anonymous users2024-02-12Sleeping without ventilation can affect health. When doors and windows are closed, the oxygen in the room gradually decreases due to lack of ventilation, and the carbon dioxide increases dramatically, especially when the room is small and crowded. According to research, after 3 hours of falling asleep, the carbon dioxide in the bedroom will increase dramatically several times, and at the same time, bacteria and dust are easy to accumulate and be inhaled into the body.
Therefore, do not close all doors and windows when you sleep at night, you can leave a ventilation window in the living room, open the bedroom door, and keep the indoor air circulation. Generally speaking, half an hour after the window is opened, the indoor air will be renewed. In the south, where there is no heating, turn on the air conditioner and turn on the temperature to the appropriate range, and leave a gap in the window.
