The importance of opening windows for ventilation and what are the benefits of opening windows for v

Frequent opening of windows for ventilation can replace the turbid air in the room, keep the air fresh, and the human body feels refreshed.

When doors and windows are closed, there will be a large amount of carbon dioxide in the air. During sleep, a person exhales 200 litres of carbon dioxide overnight. When the doors and windows are closed, the oxygen concentration in the room gradually decreases.

In the end, it is easy to cause a lack of oxygen to the brain, which seriously affects the health of the body. Open windows frequently to keep air circulating, which is conducive to expelling dirty air from the room and ensuring sufficient oxygen**.

When doors and windows are closed, there will be a lot of germs. There are a lot of bacteria and microorganisms living in the room. Because the doors and windows are closed, the air can not circulate, it provides a large number of good conditions for the breeding and reproduction of some germs, coupled with various air pollutants emitted by decorations and household appliances, etc., which can easily lead to human discomfort, such as dizziness, and easy bacterial invasion, so that people are infected and sick.

Frequent opening of windows for ventilation can effectively use sunlight and ultraviolet rays in the air to kill germs. Frequent opening of windows for ventilation can effectively remove harmful gases in the indoor air and purify the indoor air.

Everyone loves to spend time outdoors in the forests and seashores, and the natural environment makes for a good mood and a clear mind. Every corner of nature is full of negative ions. Negative ions are known as "air vitamins", which promote blood circulation, stimulate the central nervous system, and enhance cerebral cortex function.

The air of nature can contain 700 1000 negative ions per cubic centimeter; There can be 100 200 pieces of outdoor air; However, there are only 40 to 50 in the average urban living room. Therefore, it is necessary to open windows frequently to ventilate and bring more negative ions into the room.

It is important to choose the right time to open the window for ventilation.

Today we are talking about the topic of open windows and ventilation! At present, the epidemic situation is still very serious, and we must all take protective measures, not only for ourselves, but also for our families.

The benefit of opening windows for ventilation is to exchange fresh air and reduce the amount of viruses in the air. Long-term lack of ventilation will cause an increase in indoor carbon dioxide concentration, which is easy to make people feel uncomfortable and breed bacteria and viruses. Ventilation can introduce fresh air, discharge carbon dioxide, increase the oxygen content in the air, and let the bacteria and viruses in the air flow out with the air, so that ultraviolet rays can kill bacteria and viruses, improve indoor air quality, and be beneficial to health. <

1. Increase indoor oxygen. Indoor is a relatively closed space, and the human breath will release carbon dioxide, excessive carbon dioxide in the room is not good, when it reaches a certain concentration, it will also affect human health, often open windows for ventilation, can help increase the oxygen content in the indoor air.

2. Keep the air fresh. If the room is not ventilated for a long time, there will be an unpleasant pungent smell, which can easily lead to dizziness, nausea and chest tightness, which is a threat to human health.

3. Sterilization and dust removal. Long-term unventilated indoors, it is easy to breed bacteria and dust, which is easy to lead to human body discomfort, open windows for ventilation, outdoor sunlight can help kill bacteria in the air, and accelerate the spread of dust, thereby reducing the production of human respiratory diseases.

The benefits of open windows for ventilation are ().

a.Pests such as cockroaches can be reduced.

b.Reduce the spread of disease (correct answer).

c.Exhausts young children.

d.Increase the amount of carbon dioxide.

There is a high incidence of respiratory diseases in spring, and some colds are also very contagious.

Open the windows for ventilation 3 times a day, no less than 15 minutes each time, which can basically maintain the freshness of the indoor air in Luzilu.

The best time to open the window is 9:00 am to 11:00 am or 2:00 pm to 4:00 pm. Because during these two periods, the temperature has risen, the harmful gases that have accumulated in the bottom of the atmosphere have been dispersed, and the effect of opening windows for ventilation is better.

If it is raining, it is not advisable to open the window for ventilation, which will pollute the indoor air, it is recommended to close the window before and when it rains, and wait for the rain to open the window again.

It is best for the elderly and children to add some clothes before opening the window, so as not to fall ill 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.

Frequent sales of windows for ventilation can keep the indoor air fresh and circulating, and there is sufficient oxygen in the fresh air, which can promote the metabolism of the human body, which is beneficial to the growth and development of children's bodies, and can make people's minds more sober and not groggy.

If the indoor air is not circulated, it will breed a large number of bacteria, viruses and other microorganisms that may cause disease, they will usually be suspended in the air, and often open the window for ventilation, which can reduce the bacteria and viruses in the room and reduce the probability of disease.

In daily life, some tiny harmful substances will be volatilized by smoke and furniture, synthetic paper walls, paints and coatings, etc. every day; There are also some harmful substances that will volatilize after the refrigerator and color TV are turned on; After stir-frying and cooking, a variety of harmful gases are also produced in the air. People spend at least half of their time at home every day, and only by opening windows for ventilation can we reduce harmful gases and dust in the room and avoid these substances affecting the health of our respiratory tract and lungs.

It is not advisable to open more windows on cloudy days.

Because in a cloudy day with very low air pressure, the temperature inversion from the ground is maintained for a long time, and it is difficult for pollutants to dissipate, and photochemical smog may even occur, so it is most unsuitable to open windows for ventilation.

It is only after the rain that the room is really best ventilated, when a heavy rain thoroughly cleans the pollutants and the air quality is greatly improved.

No, you don't. The main purpose of opening windows for ventilation is to make indoor and outdoor air circulating, increase indoor oxygen concentration, reduce carbon dioxide, formaldehyde, dust, bacteria, viruses and other substances in indoor air, and make indoor air fresh.

As soon as the glass window is opened, the air inside and outside will flow and be exchanged. The screen window is a mesh structure, the main function is to prevent mosquitoes, and it will not affect the air circulation, so the window is not required to open the screen for ventilation.

In the north in winter, it is very cold! People like to keep their homes closed and warm for comfort. But staying in a closed house for a long time is not good for your health.

If you open the window for ventilation, the outside temperature is too low, and the wind blowing in may also trigger a cold. How to ventilate scientifically? Today, we will talk about this topic.

If the room is relatively small, and there is wind outside or the weather is cold, the window opening time should be as short as possible; If the room is large, there is no wind outside, or the weather is warmer, the window opening time can be appropriately longer. According to relevant data, an 80-year-old room can reduce pathogenic microorganisms by 60% by opening the window for 20 minutes in a breezy state.

If it happens to be a road outside and there are many pollutants, the time of opening the window for ventilation should be adjusted appropriately. A little earlier in the morning and a little later in the evening; If it is windy and sandy weather, the windows are opened a little smaller, it is recommended to install window screens and use a humidifier to increase the humidity of the air and let dust and microorganisms sink.

It is best to open the windows for ventilation at 9 a.m. at 11 a.m. and at 2 p.m. at 4 p.m. every day for no less than half an hour each time. It is not recommended to open the window more than once, because frequent window opening will lower the room temperature, and the elderly and children are susceptible to disease. It is recommended that the elderly and children should add some clothes before opening the window to avoid getting sick due to the sudden drop in temperature after opening the window.

The kitchen is an important part of indoor air pollution**, and when cooking, turn on the exhaust fan or range hood to remove harmful gases in time.

If you have a fresh air system installed in your home, you can easily enjoy fresh air without opening the window!

1.Choose the orientation: Choose a room due south, northwest, etc., so that the room can get enough fresh air in the room.

2.Open windows properly: Try not to open too many windows on windy days, as this can cause the indoor temperature to drop dramatically. On windless days and light windy days, you can open a few windows appropriately to promote indoor ventilation.

3.Pay attention to the time difference: Generally 10:00-12:00 am is the best time to open the window, as this is the part of the day when the fresh air flow is greatest.

4.Supplemental method: If you want to quickly extract the indoor exhaust gas, you can also use an electric fan to help speed up the convection effect.
