The bedroom needs to open the window frequently for ventilation, which time period is not suitable f

When the sun rises in the early morning, it is not suitable to open the window for ventilation, now the industrial development is very fast, industrial pollution, air pollution are more serious, and there is morning peak car exhaust pollution, the air in the early morning is not fresh, so it is not suitable for opening the window for ventilation.

1. On haze days, haze, and dust days, of course, close the windows. The air quality outside is so bad, don't pollute it indoors. Not only do you have to close the windows, but it is also essential to have an air purifier and humidifier in your home.

2. On rainy days, if you don't close the windows in this kind of weather, things will fly around indoors, the furniture and floors near the windows will be wet by raindrops, and the strong wind will blow pollutants to your home.

3. During peak periods, morning and evening rush hours, automobile exhaust and industrial pollution reach the maximum value, and the air quality is poor. Especially for residential houses near the road, it is best to close the doors and windows during these two times and wait until bedtime.

Midday. In the morning, the plants have not yet photosynthesized, so the air has more carbon dioxide and is not suitable for ventilation; At night, the day's dust and carbon dioxide also account for a lot of components, and plants cannot be purified because the sun sets. So, noon is the best.

Opening windows 24 hours a day for ventilation is definitely not good. Because the air quality is different at different times of the day. We often say that we should open the windows every day to ventilate the room in order to keep the space fresh and improve the air quality in the house.

Between 8 am and 10 am and 4 pm to 6 pm, the air quality during these two time periods is relatively good, and it is recommended to open the windows. The rest of the time, because traffic congestion generates a lot of exhaust fumes. If you open the windows for ventilation, then the air quality in exchange is not very good.

In addition, if there is a haze weather, everyone has closed doors and windows, how can they open the windows for ventilation? In hazy weather, the air quality outside is very poor, and you must wear a mask when you go out, otherwise you will inhale a lot of dust and harmful substances.

If you open the windows of your home at this time, then you are inviting these harmful substances into the house, isn't it stupid?

If you leave the windows open all day, if it rains, the humidity of the air in the house will be high, which may also affect the furniture. Especially in the south, if there is a southerly wind or rainy weather, the air is very humid.

At this time, everyone has closed doors and windows, and sometimes even has to prescribe dehumidifier, otherwise the whole house will be wet. If you open the windows again at this time, it will be a nightmare, and it will also cause damage to the wooden furniture in the house.

You can open the window half an hour before going to bed at night, and it is not advisable to open the window again when it is time to sleep. Because many houses are facing the road nowadays, if you sleep with the windows open, the noisy noise on the road will make you sleep badly.

In addition, there is a lot of dew in the morning, and the humidity of the air is also high. Long-term window opening time is also not good for the respiratory tract.

In winter, the room also needs to open windows for ventilation. As long as the windows are opened every day for ventilation, the air in the house can be kept fresh. Open ventilation can be good for the body. The air in the house needs to be changed every day. Therefore, in winter, the room also needs to open the window for ventilation.

Hello! We are the **** life experience officer of Zhejiang Antke Technology:

In winter, it is best to open the windows three times a day in the morning, noon and evening for ventilation.

What is the importance of opening windows for ventilation in winter:

First, it is best to open the window for ventilation three times a day in the morning, noon and evening, not the more times the window is opened, the better, the frequent opening of the window will reduce the room temperature, which is easy to cause the elderly and children to get sick. Generally, open the window for ventilation 3-4 times a day, 30 minutes at a time is enough, taking a space of 100 cubic meters as an example, in the absence of wind, about 11 minutes can make the air exchange again.

Second, if the room is small, and it is windy or cool outside, the window opening time should be shorter; If the room is large, and there is no wind or warmth outside, the window should be opened for a longer time.

Third, it is best for the elderly and children to add some clothes before opening the window, so as not to get sick due to the sudden drop in room temperature after opening the window. The elderly and children should also try to move less by the window at this time, if the window is facing the bed of the elderly and children, you can only open a small gap to produce air convection.

Fourth, if there are seriously ill patients, they should carefully open the windows and try to use ultraviolet disinfection lamps.

to purify the air. It should be noted that the indoor temperature should not drop below 16 due to the opening of the window, and it is best to control it at 16 22.

Hope it helps!

In winter, you also need to open the window for ventilation, the home is warm, but if you don't open the window for a long time, the air at home will not be good and will not be circulated, which is harmful to the human body, so the home should open the window regularly for ventilation, especially in the newly renovated house, it is necessary to open the window for ventilation.

Introduction: In winter, it is necessary to keep warm in time, so as to maintain the indoor body temperature and make people's lives more comfortable, so should we open more windows for ventilation in winter? Why?

In winter, people always choose to keep the windows closed, and it is too cold to go outside, and if the windows are opened, the indoor temperature will be lowered, which will affect people's health. But in fact, if things can't be opened directly to ventilate, it will also cause a series of problems, such as carbon dioxide in the room.

If the concentration is too high, the multiplication of various microorganisms will affect the quality of people's breathing, so it is necessary to open windows for ventilation. The windows can be opened between 10 a.m. and 3 p.m., which is a good estimate. And it can replace the bad air in the room, so that you can breathe your own airways.

The air will also be fresher, so you can also protect your health. In addition, you can also leave a small slit in the window when you sleep in winter, so that you can breathe fresh air while sleeping, and you can also make your body healthier. In winter, if you can properly open the windows for ventilation, then you can regulate your body temperature.

Get better. <>

In fact, it is more likely to have physical problems in winter, because the weather in winter is relatively cold, so many elderly people can't stand it, and naturally will encounter a series of problems. In addition, when the weather is cold in winter, it can also cause joint pain in young people.

Therefore, it is necessary to keep warm in winter, especially the lower limbs should be kept warm in time, and you can choose to soak your feet before going to bed at night, so that you can make your body healthier. At the same time, you should also pay attention to the fact that when you are indoors, you can do some indoor exercises, so that you can enhance your physical fitness even more.

In this way, you can also ensure your health and eat more fresh vegetables and fruits in winter.

The windows should be opened for ventilation, because there will be a lot of bacteria breeding in the house in winter, and there is no fresh air, which will cause certain impact and damage.

Yes, because in this way, the indoor temperature can be guaranteed, the air circulation can be promoted, the quality of the air can be guaranteed, and the person's own immunity can be improved.

In winter, you should open more windows for ventilation, because this can prevent some diseases and cold symptoms.

One to winter, people are used to being in the winter, indoors is summer, wearing bears outside, wearing shorts in the house, eating ice cream! Windows are strict, in fact, this is because of a big hidden danger that leads to our health problems! First of all, the opening time is not less than 45 minutes.

The number of openings is not, the windows are opened 3 times a day for no less than 15 minutes each time, basically keeping the indoor air fresh.

Second, as long as you open the window with the stove. Many people think they don't have to open the windows when they're not cooking. In fact, even if it's just burning water, the exhaust fumes of the gas are simple, walk to the living room and bedroom.

Therefore, when gas is used, it doesn't matter how the cooking is to open the window or use the hood.

Thirdly, the windows can be correctly spotted when sleeping in winter. When you sleep in winter, many people always like to end the window to avoid catching a cold. In fact, when sleeping in winter, the windows allow you to swim while sleeping in winter, but avoid the wind and don't let it blow directly.

Sick or experiencing strong winds, it is not appropriate to open windows during heavy rain.

Fourth, the best window is 10:00 to 3:00 p.m.

Before going to work in the morning, many people get used to the window and come back at night. According to research, the city's two air-polluted peaks usually appear before sunrise, which is the most inopportune window of time, according to research. The two periods of relative air cleanliness are 10 a.m. and 3 p.m., advocating that we open our windows in this moment.

Fifth, smog days need to be closed. Some people say that the smoke outside the smoke is relatively large, so close the windows to prevent the smoke, when in fact the windows are small, and use a humidifier, moisturize spray, or put a basin of water on the heat to add air humidity so that dust and microorganisms will sink.

Sixth, natural ventilation is king. Someone bought an air purifier and I think it's good, the usual air purifiers on the market now can only remove dust, except for smoke and odors, and kill bacteria and viruses slightly better. However, secondary pollution may be present in enclosed spaces, and when air quality is improved, there is no need to turn on the air purifier for a long time and should be chosen in natural ventilation.

Poor breathing, dryness. If the air is not circulated, the gas will accumulate more and more after a while, which can easily lead to nasal congestion. Enclosed spaces lead to dryness indoors, and there is an increasing lack of water.

It is easy to get sick, the air is not circulated, viruses and bacteria are easy to breed, and a large number of them will cause people to get sick.

It is easy to get dizzy due to lack of oxygen. Because the air in the room is limited, if the outside oxygen cannot enter the room, there is a high risk of insufficient oxygen.

In this way, the air quality inside the room will be poorer, and it will also make people's physical fitness worse and worse, and then it is easy to develop respiratory diseases.

I think that if you do this, you will not be able to breathe fresh air, and if you grow in a polluted environment for a long time, it will naturally cause respiratory problems. It is very dangerous.

15-20 minutes.

Opening windows for ventilation can enable people to obtain more "air vitamins", that is, negative ions, which can increase the body's resistance and prevent diseases. In the cold winter, open the windows every day for ventilation, preferably once in the morning, noon and evening, for 15 to 20 minutes each time. There are two pollution peaks and two relatively clean troughs in the urban atmosphere during the day and night.

The two peaks are generally around sunrise and in the evening, so it is best to open the window at 9 a.m. to 11 a.m. or 2 p.m. to 4 p.m.

Because during these two periods, the temperature has risen, the harmful gases in the bottom layer of the atmosphere have been dissipated, and the effect of opening windows for ventilation is better. Even on smog days, open the windows for ventilation, and you can open a small slit in the windows of each room to ventilate. Generally speaking, between 1 p.m. and 4 p.m. every day, the atmospheric diffusion conditions are relatively good, and the pollutant concentration is low, which is the best time for ventilation.

Opening the windows 3 to 4 times a day, 30 minutes at a time is enough. In a space of 100 cubic meters, for example, when there is no wind and the temperature difference between indoor and outdoor is 20, it takes about 11 minutes to exchange air. The frequency of ventilation can be decided according to psychological needs, and for office workers, it is enough to maintain ventilation during the home period.

Three tips for ventilation.

Although most citizens have the habit of waking up early in the morning and opening windows to ventilate, early morning ventilation may not be appropriate in the context of modern industrial pollution and increased vehicle exhaust. Air pollution has two peaks day and night, as well as two relatively clean troughs. The two peaks are generally around sunrise and in the evening, and the two relatively clean periods are around 10 a.m. and 3 p.m.

Therefore, the public can choose the window opening time according to the actual situation in the area, and it is best to avoid the two pollution peaks in the morning and evening, which is one of them.

Second, don't open the door all day long, open the window 3 to 4 times a day, 30 minutes at a time is enough. In a space of 100 cubic meters, for example, when there is no wind and the temperature difference between indoor and outdoor is 20, it takes about 11 minutes to exchange air. The frequency of ventilation can be decided according to psychological needs, and for office workers, it is enough to maintain ventilation during the home period.

Third, it is not advisable to open more windows on cloudy days, and the choice of ventilation is also different under different climatic conditions. Pollutants are cleaned in rainy and snowy days, and pollutants are easy to dissipate when the wind blows, and the air quality in this weather is higher, so citizens can open more windows appropriately. However, on a cloudy day with very low air pressure, the temperature inversion from the ground does not disappear for a long time, and it is difficult for pollutants to dissipate, and even photochemical smog occurs, so it is not appropriate to open windows and go outdoors.

How can you tell if ventilation is effective? Expert: Open the windows for ventilation three times a day for 30 minutes each time.

That's at least two hours or more!

Hello, it is best to open the window every day to ventilate the time in combination with the environmental situation of your own home.

For example, on the side of the road, there is more dust and the traffic flow is relatively large, so you can choose to open the windows for ventilation at different times.

If the window is facing the residential area or in the effective area, the environment is relatively quiet, and the window opening time can be longer.

100% focus on window opening for 20 years.
