In winter, the cold weather continues, which means that you spend more time indoors. However, while the time spent indoors increases, it is cold when the door is left open, and ventilation is neglected because the indoor heat escapes. In addition, there are many cases where ventilation is not frequent due to the fine dust contained in the air. If the indoor air that stays for a long time is not properly ventilated, pollutants, carbon dioxide, and fine dust contained in the air continue to accumulate. And if you are continuously exposed to these accumulated pollutants, the air becomes more turbid and drier, which threatens your health. Because polluted indoor air flows into the body faster than outdoor air, it not only causes headaches, fatigue, and colds, but also increases the risk of lung and respiratory diseases. In particular, it is known that if you have atopic dermatitis and allergic diseases, the symptoms will get worse if ventilation is not done well. So, today we are going to talk about how to ventilate the room in winter. How to ventilate the room in winter
1. 3 times a day, 10 minutes of ventilation
In order to ventilate the room in winter, it is recommended to ventilate the room 3 times a day for 10 minutes each. In winter, the temperature difference between indoors and outdoors is large compared to other seasons, so air circulates quickly. In the early morning or at night when the atmosphere is stagnant, it is recommended to ventilate during the sunny hours between 9am and 6pm, as polluted air is on the floor. In addition, since the indoor air becomes turbid in a space where many people gather, it is recommended to ventilate the room for 10 minutes at intervals of 1 to 2 hours.
2. Open windows and doors to ventilate
When ventilating, it is recommended to open windows and doors as wide as possible, and to circulate the air quickly by using a cross-wind ventilation method. Also, when ventilating for cleaning, it is recommended not only to open the windows, but also to open all doors such as wardrobe doors, cabinet doors, and doors to circulate the air properly. Since the dust that has settled on the indoor floor is covered with contaminants and heavy metals, it is a good idea to wipe with water after wearing a mask. Also, when using a heater, it is recommended to open the window and ventilate for at least 30 minutes before and after using the heater to improve indoor air quality and remove contaminants inside the heater.
3. Reduce ventilation time on days with severe fine dust
On days with poor air quality and severe fine dust, it is recommended to provide short, periodic ventilation for about 1 to 3 minutes. After ventilating, it is a good way to spray a sprayer to calm the fine dust floating in the air, and then use a damp cloth to wipe off the fine dust that has settled on the floor. However, on days when the concentration of fine dust is too high, it is recommended not to ventilate for a day or so. Instead, using products such as an air purifier can be a good way to keep the indoor air pleasant. In the case of air purifiers, it is important to periodically clean and replace the filter because contaminants can form in the filter that purifies the air.
4. Ventilation before and after cooking
When cooking, a lot of heat of combustion, moisture, and smoke are emitted during the process of baking or frying, so pollutants and fine dust are rapidly increasing indoors. These increased pollutants spread not only in the kitchen, but also throughout the living space, such as the living room and bedroom, and adversely affect health. Therefore, it is recommended to turn on the fan for about 5 minutes before starting cooking to allow air circulation, and after cooking, operate the hood for at least 30 minutes and open the window for natural ventilation for at least 15 minutes.
In addition to the various methods introduced above, it is said that it is a good way to put air-purifying plants, charcoal, coffee grounds, etc. to maintain a comfortable indoor air. In particular, air purifying plants are said to have a good effect not only in maintaining proper indoor humidity in winter, which is easy to dry, but also in reducing emotional stability and stress.
