In life, in order to ensure that the indoor air is fresh, we will develop a good habit of regular ventilation.
Every morning when I open the window, I can smell the fresh air and feel much more awake in an instant!
Frequent opening of windows for ventilation can allow the indoor air to circulate quickly and increase the oxygen content!
It's just that we are also very particular about opening windows for ventilation, and the wrong method may affect your ventilation effect, so you should pay attention!
"If you don't open the window at three o'clock, your family will be less sick"! It is recommended not to open the window at these 3 times, it is not superstition, let's take a look!
1. It is not advisable to open the window when it rains
On rainy days, many people may get used to opening their windows and enjoying the seemingly fresher air.
But you're not doing it right, and while the air after the rain does feel fresh and pleasant, it's a different story when it rains.
Rainwater is not so clean, and it can carry acids in the air, which often come from sources of pollution such as industrial production and vehicle exhaust. When these acids are mixed with rainwater, they form what we commonly refer to as "acid rain".
Acid rain is not only harmful to human health, but can also cause serious damage to buildings, soil, and vegetation.
Rainwater can also be mixed with other pollutants as it falls.
These pollutants can come from tiny particles such as dust and pollen in the air, or they can be harmful gases emitted from nearby factories.
These pollutants are adsorbed by rainwater and scattered as rainwater falls, and if the windows are opened at this time, these pollutants may take the opportunity to invade the room, affect indoor air quality, and even pose a threat to our health.
2. It is not advisable to open the window during the morning and evening rush hours
In the busy city, traffic jams during the morning and evening rush hours are commonplace.
Countless vehicles drove slowly along the narrow road, exhaust fumes filling the air like wisps of smoke.
Car exhaust, a seemingly trivial problem, actually has a serious impact on the environment. They contain a variety of harmful substances such as carbon dioxide, carbon monoxide, nitrogen oxides, etc.
In such a situation, many people may mistakenly believe that opening windows can ventilate and freshen indoor air. However, this is not the case. During peak periods, the concentration of pollutants in the outdoor air often exceeds that of the indoor air, and opening the windows at this time not only does not achieve the effect of ventilation, but may bring outdoor pollutants into the room, bringing potential threats to people's health.
Therefore, during the morning and evening rush hours, for the health of your family, it is recommended that you try to close the windows and use equipment such as air purifiers to keep the indoor air fresh. In this way, you can avoid outdoor pollutants and ensure the quality of indoor air.
3. The windows should not be opened at night
At night, as night falls, the outside temperature gradually decreases, and the humidity of the air also changes.
At this time, if you open the windows at will, you may let in the cold air, humidity and even dust particles from the outside world, which will have a negative impact on the health of the occupants.
Opening the window at night is easy to make the body cold. Especially in spring and autumn, the temperature difference between day and night is large, and the cold wind invades after opening the window, which can easily cause the human body to suffer from cold, causing colds, coughs and other respiratory diseases.
Especially for the elderly and children and other people with weak physique, they should pay more attention to keeping warm and avoid opening windows at night.
Night is a critical time for the body to rest and rejuvenate, and external noise, light and other factors may interfere with sleep.
After the window is opened, the noise and light from the outside world can easily enter the room through the window, affecting people's sleep quality, which may lead to neurasthenia, insomnia and other problems in the long run.
Write at the end:
Opening windows for ventilation is also very particular, everyone must learn the correct method, don't be careless!
