Should the bedroom be ventilated?

Whether the bedroom should be ventilated or not, the indoor air quality standard is one of the important signs to improve the quality of life. In general, people will open the windows to let the indoor air circulate, but many people will struggle to ventilate when they sleep. This is whether the bedroom should be ventilated.

Should the bedroom be ventilated? 1 There are many microorganisms in the room besides people. Usually, when people are not at home during the day, doors and windows are locked, indoor air is not circulated, and indoor aerobic bacteria will consume a lot of indoor oxygen.

Produce some metabolic waste gas, such as carbon dioxide and nitride. At night, with the lack of oxygen indoors, anaerobic bacteria begin to get excited, such as common mold. Ventilation before going to bed is to eliminate indoor harmful gases, provide oxygen for sleep and update indoor air quality.

Close the window when you sleep, because there are many nocturnal insects at night, such as mosquitoes. Closing the window can avoid the impact of this insect on sleep, and it is also safer and quieter. Of course, at night, the surrounding trees stop photosynthesis, the respiration is enhanced, and the concentration of carbon dioxide is gradually increasing. Instead, you can't breathe fresh air when you open the window. I hope I can help you.

Do you need indoor ventilation when you sleep?

Whether it is winter or summer, it is actually recommended to open the window for ventilation when sleeping, which can ventilate the room and is beneficial to the human body. It may be cold in winter, and many people sleep with their windows closed.

But we suggest that it is best to open the window for ventilation, even a little, so that indoor ventilation is beneficial to human physical and mental health. I love to close the windows in winter, and the indoor ventilation is not very good, which is not good for the quality of sleep.

Therefore, the quality of sleep in winter is healthy, and it is very important to keep warm and cold. Pay attention to warm body and cool head, and the quality of sleep is safe. People with anemia have poor blood circulation system and are particularly afraid of cold, so it is best to use a warm handbag or an electric mattress to help keep warm when sleeping. The most suitable temperature for sleeping is close to human body temperature. If the temperature is too low, the sleep time may be delayed.

Do you want to air the bedroom? 2. Window ventilation time

1, get up in the morning, after a night's sleep, a lot of carbon dioxide has accumulated in the indoor air, reducing the oxygen content. Therefore, it is suggested that opening the window for ventilation at this time can make the indoor air flow and let fresh air enter the room.

2. Around eight o'clock in the morning, because the air quality is good during this time, it is suitable for ventilation.

When cooking, it ends ten minutes after dinner. There will be a lot of smoke in the kitchen when cooking. After dinner, we need to keep the window open for ten minutes. This can completely exhaust the kitchen fumes and make the indoor air better.

4. After taking a bath at night. After taking a shower, the bathroom will be very humid and produce a lot of steam. At this time, it is suggested to open the window in time for ventilation to reduce bacterial growth.

5. It takes about 15 minutes to open the window for ventilation before going to bed to ensure that there is enough fresh air in the room.

6. Open the window for ventilation after cleaning. After cleaning the room, there will be a lot of dust and other pollutants in the air. You should open the window to ventilate and let these dust pollutants out.

Can I open the window for ventilation 24 hours a day?

Not so good.

Generally speaking, 24-hour ventilation is not recommended for two main reasons. First, there are many pollutants such as outdoor dust and tail gas, and long-term ventilation will make these pollutants enter the room and affect the indoor air; On the other hand, because the temperature outside is too low in winter, it is easy to catch a cold by introducing cold air for a long time.

How many minutes does it take to open the window for ventilation in winter?

15-20 minutes.

In winter, it is generally recommended that the ventilation time be around 15-20 minutes. Ventilation time 15-20 minutes can basically change the indoor air and make it fresh. Too long ventilation time can easily lead to colds or exhaust gas entering the room.

When is it not appropriate to open the window for ventilation?

When air pollution is serious

In some cities, or in some bad weather, the air pollution outside is serious. At this time, it is generally not recommended to open the window for ventilation, so as not to affect health. Even if ventilation is needed, choose a time with less pollution, such as 8 am or 6 pm.

When it rains

When it rains, it is generally not recommended to open the window for ventilation, because there are many pollutants in the rain, and it is easy to enter the room with the rain after opening the window. It is generally suggested that ventilation is better after rain.

When there is a lot of pollen in spring.

If you have allergic rhinitis or pharyngitis at home, you should also reduce ventilation in spring to prevent pollen from entering the room and inducing allergies.

Do you want to air the bedroom? 3. How big is ventilation window?

The bigger the better.

The larger the window area, the better the air circulation effect. However, due to the different decoration of each family bedroom window, it is suggested that a bedroom of about 12 square meters with a fan of 600mm× 1000mm can meet the ventilation requirements.

A living room of about 20 square meters has two 600mm× 1000mm fans. 4 square meters of bathroom, there is a 600mm×600mm open fan is enough; The ventilation requirements of the kitchen are higher, about 5-6 square meters. A kitchen with a 600mm× 1000mm fan can also meet the requirements.

How about a small crack in the window for ventilation?

Might as well open a big window.

When the temperature is low in winter, if the window is opened too wide and cold air enters, it is easy to catch a cold. At this time, it is suggested to open a small window and leave a gap, which is also conducive to reducing the number of toxic substances harmful to human health such as bacteria and dust. However, opening a small window is not as effective as opening a large window in air replacement, and it takes a relatively long time to open a small window for air replacement, generally more than 30 minutes.

Does ventilation have to be convective?

Convection is the best and ventilation effect is better.

When two windows form convection, the air propagation efficiency is several orders of magnitude higher than that of a family with only one window. If it is windy outside, the air quality of the whole room will be consistent with that outside in a few minutes. But many families don't have convection windows, so they can only open one window. In this case, opening a window for a family for not less than 15 minutes can also meet the requirements of room ventilation.

When should I open the window every day?

9- 10 in the morning and 3-4 in the afternoon.

On the one hand, open windows in these two time periods to avoid the worst air during peak hours; On the other hand, when the temperature rises, the harmful gases deposited at the bottom of the atmosphere have dispersed. Window ventilation can blow harmful gases and even pathogens to the outside through air circulation, and dilute the content of harmful gases or germs indoors, thus indirectly achieving the purpose of air disinfection.

How to open the window correctly

1, time period: 8: 00-1:00, 13: 00-16: 00.

The concentration of air pollutants in these two periods is low, so windows can be opened in time for ventilation. Among them, 10 am and 3pm are prime time for window opening. Street residents should pay attention to avoid morning and evening rush hours.

2. Duration: about 30 minutes.

Open the window for about half an hour at a time. If only a small slit is made in the window of each room, the duration should be increased to 30 minutes-1 hour.

3. Times: 3 times a day

When the weather is fine, open the window at least three times a day. Ventilation should be done regularly in the morning, at noon and at night.

4. Mode: Convective ventilation

Open the farthest two windows at the same time, so that the ventilation efficiency is the highest. Alternate ventilation can also be used. Let one room open the window to ventilate first, then close the window after 30 minutes, and then open the window of the other room to ventilate.

pay attention to

After opening the window, if the temperature difference between indoor and outdoor is large, the room temperature may plummet. Be sure to keep warm. You can put on your coat before opening the window, or rest in another room for the time being.
