Shouldn t you open the window for ventilation in the early morning When you open the window for vent

1 What time in the morning is suitable for opening windows for ventilation.

It depends on the living environment.

For example, the two peaks of air pollution in the city are generally around sunrise and in the evening, which is the most unsuitable time to open windows. The correct thing to do is to open the windows for ventilation from 10 am to 4 pm every day, during this time there is less dust in the air and the air quality is relatively low.

Relatively good; However, if you live in the countryside, because the population is not as dense as the city, the air quality is much better, so you can open the window for ventilation a little earlier, and it is more appropriate to open the window for ventilation at 7-10 o'clock in the morning.

2 How long does it take to open the window for ventilation?

The duration and frequency of ventilation should be specific to the indoor and outdoor environmental conditions.

If the outdoor air quality is good, it can be ventilated in the morning, noon and evening, and the time is 15-30 minutes each time, while when the outdoor air quality is poor, the frequency and time of ventilation should be appropriately reduced. Under normal conditions, a space of 100 cubic meters is outdoors in a windless room with a temperature difference of 20 degrees Celsius.

, it takes about 11 minutes for the air to be exchanged. Under normal circumstances, you can ventilate for more than ten minutes to half an hour in the morning or at noon when the weather is good every day, but it should also be determined in combination with the weather situation, like rainy weather, it is not advisable to open more windows, because the air pressure of the weather is very low at this time, and some pollutants on the ground are not easy to diffuse, and it is easy to enter the room from the window.

3 Is it good to open windows for ventilation 24 hours a day?

Not good. Although opening windows for ventilation has to displace the air, improve air quality and avoid bacteria and viruses.

The effect of breeding, but this benefit is based on the air *** situation, and different times of the day, the air quality is different, if the window ventilation is opened in the stage of traffic congestion when a large amount of exhaust gas is generated, then it will bring bad air into the room, which is not conducive to physical health, in addition to rain, snow, haze weather.

It is not advisable to open windows for ventilation in dusty weather.

4 Do I need to open the window for ventilation to turn on the air conditioner?

Ventilation needs to be opened for ventilation.

1. In the early morning, the outdoor air is fresh and cool, and there is no need to turn on the air conditioner at this time, all the windows can be opened to make the outdoor fresh air enter the room as much as possible.

Between 00-15:00 is the hottest time, turn on the air conditioner appropriately, and ventilate for 10 minutes before turning on; After 1-3 hours of activation, turn off the air conditioner and open the windows for ventilation. An electric fan can be used if necessary.

Or the ventilation fan is sent out to convection of indoor and outdoor air, so that the exhaust gas and harmful gases can be discharged outside. Ventilate for at least 20-30 minutes, then close doors and windows and restart the air conditioner.

3. For people who work in office buildings, they should ventilate for 20 minutes every 1-2 hours in an air-conditioned environment, which can avoid air-conditioning diseases caused by excessive temperature difference between indoor and outdoor.

It can also ensure that the brain is awake during work and improve work efficiency.

Early morning temperatures are lowest and air pressure is highest. Due to the high air pressure, the dirty things in the air, such as fine sand and dust, and bad gases, are pressed close to the ground by the high atmospheric pressure in the morning, and it is difficult to release them into the air. In other words, early morning is the time of day when ground air pollution is at its worst, and air quality close to the ground is the worst.

If the window is opened for ventilation at this time, not only can it not achieve the purpose of fresh indoor air, but it is also easy to introduce undesirable outdoor gases into the room.

Therefore, it is not advisable to rush to open the window for ventilation in the early morning, and it is best to wait until the foul air deposited on the ground is lifted into the air before opening the window for ventilation. For example, at 9 11 o'clock in the morning or 2 to 4 o'clock in the afternoon, the temperature rises and the air quality is better, which is the best time to open the window for ventilation.

At about 6 o'clock in the morning, the concentration of pollutants is still very high, and the temperature in the early morning is low, the air pressure is high, the tiny dust and bad gases in the air are pressed to the ground by atmospheric pressure, it is difficult to dissipate to the high altitude, only when the sun rises, the temperature rises and the harmful gases will slowly disperse. Before and after dark, as the temperature drops, dust and various harmful gases begin to deposit on the ground, and it is not suitable to open windows for ventilation. The best time to open windows for ventilation is between 9-10 a.m. and 3-4 p.m.

As the temperature rises during these two periods, the countertroposphere phenomenon has disappeared and the harmful gases deposited in the lower atmosphere have dissipated.

For lanes with large traffic flow, because the atmosphere at the bottom at night is more stable than during the day, and the wind speed is generally smaller, many pollutants cannot be diluted and diffused, so generally around 7:30 in the morning, the concentration of pollutants is generally relatively high, so for people who generally live on both sides of the street, it is best not to open the windows in the early morning for ventilation.

The temperature is the lowest in the early morning, but the air pressure is relatively high, so the fine sand and dust in the air and some undesirable gases and other pollutants are pressed close to the ground by the higher air pressure in the morning, so this time is the time of the day when the ground air pollution is the most serious, especially the air close to the ground, the quality is the worst.

Therefore, generally around 9 o'clock before work, the temperature is higher, and the air quality will be better, this time is a good time to open the window for ventilation, in addition, plant some green plants in front of the window, which will make the morning air clearer.

It is not advisable to open the window for ventilation in the morning, most people have the habit of getting up early in the morning and opening the window for ventilation, but in the case of modern industrial pollution and aggravated automobile exhaust, early morning ventilation may not be appropriate.

In the early morning, if the weather is good, you can open the window if there is sunshine, and it is best not to open the window if there is haze or wind outside or the weather is gloomy.

It is indeed not advisable to open the windows for ventilation in the early morning.

Reason 1: The temperature is low in the early morning, and opening the window is easy to cause colds.

When you wake up in the morning, the temperature inside and outside is very high, and it is easy to catch a cold when it is cold and hot.

Reason 2: The dust and particulate matter in the air have not yet drifted away.

In the morning traffic morning rush hour car exhaust, last night's life exhaust has not dissipated, opening the window in the morning will reduce the indoor air quality.

This also depends on the region, and some areas are really not suitable for this time in the city. Rural areas don't have much of an impact.

The air is still cold in the morning, so the room should be warmer in the morning.

It is not advisable to open the window for ventilation in the morning, there is more dust in the morning, and it is better to open the window at noon.

In the early morning, it is not advisable to open the windows for ventilation. Most people think that getting up in the morning and opening the habitually closed doors and windows to ventilate the room can release the "turbidity" in the room and turn it into natural and fresh air, but in fact, this is not right. Opening windows early in the morning for ventilation is not good for health.

It looks pleasant to get up in the morning and open the window for air, but for people living in the city, this method is not advisable. Especially for some streets with high traffic, the lower atmosphere of the city at night is more stable than during the day, which is less conducive to the dispersion of pollutants. So the pollutant concentration is still very high around 6 a.m.

The temperature is low in the early morning and the air pressure is high. Small dust and undesirable gases in the air are squeezed close to the ground by atmospheric pressure, and it is difficult to dissipate them into the air.

If you want to sleep***, you need plenty of oxygen in the room, but the bedroom may not have as much oxygen until night, so you can open the window to ventilate. The ventilation time should not be too long, a few minutes is enough, and it will not affect everyone's sleep time. Of course, if there is a peculiar smell outside, or if the outdoor traffic line is in high traffic hours, there is no need to open the windows.

Also pay attention to the air conditions outside and do not open the windows when it rains. Open the windows on rainy days, the rain can easily splash into the room, the room will become damp, and the rain will also contain pollutants when it rains. You can open the windows after the rain because the air is a little humid after the rain and there is no dust floating around.

Frequently open windows for ventilation can effectively use sunlight and ultraviolet rays in the air, kill germs, remove harmful gases in the indoor air, and purify the air. Frequent ventilation can prevent the quilt from getting damp and prevent the growth of mites and fungi. Improve the body's immunity and reduce respiratory diseases.

It is best to ventilate once a day in the morning and once in the afternoon for half an hour at a time. But be careful, in case of haze weather, bad air quality weather, do not open the window to prevent outdoor air pollution.

No, you should open the windows in the early morning to ventilate, because the air quality is very high and the air is very fresh.

You can open the window to ventilate when you get up in the morning, the exhaust gas is stuffy in the room overnight, and it is very good to open the window for ventilation, but be careful not to blow a cold, after all, just got up, and the body is easy to catch a cold.

No. In the morning, you should open the windows for ventilation, so that you can breathe fresh air, improve the body's resistance and immunity, and purify the indoor air.

Nowadays, whether it is study or work, most of them are done indoors, but after staying indoors for a long time, it is very necessary to breathe fresh air and open windows for ventilation, especially in the morning, many people like to open windows for ventilation, which can not only breathe fresh air, but also promote the circulation of air in the room. Especially in the summer, even when the air conditioner is turned on, you can feel the slow air circulationThere will even be a little bit of suffocation. In such a situation, opening windows for ventilation is very useful and allows us to breathe fresh air.

The benefits of opening windows in the morning for some students, including office workers, are only at home after returning home from work and before going to work on the second morning. But whether at home or at night, we absorb a lot of oxygen and release a lot of carbon dioxide as we breathe.

Especially in the morning, when the concentration of carbon dioxide is at its highest, opening the windows for ventilation can allow the air to circulate in the houseTaking away some of the carbon dioxide and infusing the room with some oxygen allows us to breathe fresh air, which is great for health when fresh air and oxygen enter the body.

In the process of opening windows and ventilating windows, it can reduce the concentration of indoor bacteria and viruses, and when the concentration of bacteria and viruses decreases, it can reduce the possibility of respiratory diseases. Including in the process of opening windows for ventilation, there is also sunlightUltraviolet raysIt also has a good effect on air purification, which can kill some viruses and bacteria in the process, and make the air in the room fresh.

Whether we are at school or at home, we should open the windows frequently, because the fresh air brought by opening the windows for ventilation is very different from the air conditioners we turn on in our daily lives. Therefore, even if the indoor air is cooler due to the air conditioning, we also need to open the windows for ventilation.

Many people think that the indoor environment is very clean, but even in such a clean environment, there are bacteria and viruses breeding, so whether it is through the opening of windows to ventilate to take away viruses and bacteria,Or by killing viruses and bacteria through ultraviolet radiation, it can improve our immunity and reduce itRespiratory tractThe possibility of the occurrence of systemic diseases.

Opening windows can keep the air fresh in the house: In the room with closed doors and windows, there is a special smell, which is a lack of oxygen, which can cause headaches, palpitations, fatigue, and increased blood pressure. Open the window, the foul "room smell" will come out of the window, and the window can destroy the growth environment of the child

Unventilated rooms with low humidity are most conducive to the spread of pneumococcal A. Ultraviolet rays from sunlight have a disinfecting effect. Opening windows for ventilation can make people get more "air vitamins" - negative ions:

This is beneficial to regulate the central nervous system and improve immunity.

In order to let the fresh air outside flow into the room and make the air in the house fresh, it is good for the body to open the window to facilitate air circulation, reduce the breeding of indoor germs, and is conducive to the health of the respiratory tract

The advantage of this is that it can let some fresh air enter the house as soon as possible, so that the oxygen in the house can circulate quickly, so that the human body can breathe fresh oxygen, which is very good for the body, purify the gas in the house, so that the quilt will not be damp, avoid the breeding of mites and mold, improve immunity, reduce respiratory diseases, etc.

After opening the window for ventilation, the air in the room can be circulated, and you can breathe fresh air, which has many health benefits, can prevent respiratory diseases, and purify the air.

This is good for the body, it can allow people to breathe fresh air, exhaust harmful gases in the room, and make the atmosphere of the home better, which is conducive to people's soberness.

It can increase the concentration of negative ions in the room, which can improve the immune system, improve the immune system, and can also improve the respiratory and nervous system function.
