"If you don't open the window at four o'clock, your family will be less sick", if you can't open the window at these four times, it will be better for your family
In our daily lives, we often hear family members emphasize the importance of opening windows for ventilation and ventilation. Even if the interior of the house looks clean, people still insist on opening the windows regularly, which has become a habit that has been passed down from generation to generation.
When the weather is clear and sunny, people tend to open the windows to let the warm sunlight penetrate the room, which has a germicidal and disinfecting effect. And when the air is fresh after the rain, it is also a good time to open the windows, so that the stale air in the room can flow out and the fresh air can pour in.
Opening windows for ventilation is not just a simple habit, but closely related to human health. The proverb handed down from our ancestors is as it says: "If you don't open the window at four o'clock, your family will be less sick." This sentence points out that the timing of the opening of the window is crucial, and that the improper timing of the opening of the window can cause adverse health effects and even cause disease.
People's attention to indoor ventilation can be traced back to the wisdom of ancient architecture. Looking at the houses built by our ancestors, we can see that the roof tiles were cleverly stacked, leaving gaps that allow the air to circulate smoothly with the natural wind.
In caves and yurts in the Northwest Territories, the need for ventilation was taken into account when construction, leaving ingenious vents and ceiling holes. These designs not only reflect the inheritance of wisdom, but also provide an effective ventilation mechanism.
The Yellow Emperor's Neijing points out that "harmony with yin and yang, and peace in residence", emphasizing the impact of a suitable environment on the human body. An environment conducive to physical and mental health must be well ventilated. Opening windows for ventilation not only keeps indoor air fresh, but also reduces the risk of respiratory diseases.
Maybe you've had the experience of staying in a closed room for a long time, without opening the curtains or ventilating, and the outside air comes in with a peculiar smell. This is actually a sign of oxygen deficiency. Spending a long time in such an environment can lead to mild symptoms such as headaches, palpitations, and even serious problems such as increased blood pressure.
In environments with lack of ventilation and low humidity, bacteria, such as pneumococcus A, spread easily and pose a significant threat to human health.
Opening windows for ventilation not only allows sunlight to fill the room, but the ultraviolet rays in the sunlight have a powerful disinfecting effect. Under the action of ultraviolet rays, bacteria in the air are effectively killed. The introduction of fresh air not only removes the turbidity and heat from the room, but also eliminates odors, which is beneficial to the health of the respiratory system.
In daily life, we should pay special attention to the choice of "four", because the timing of opening windows for ventilation is related to the exchange of indoor and outdoor air, which has an important impact on physical health.
As we all know, in the face of severe polluted weather, such as haze and other bad weather, it is absolutely not necessary to open windows for ventilation.
Sometimes, when we wake up in the morning, there may be a light fog outside the window, and we mistake it for a natural sight in the morning, believing that the sun will dispel the fog as soon as it rises. Therefore, we did not hesitate to open the windows and look forward to welcoming the fresh air.
In fact, the fog outside the window may be a haze, which contains a large amount of airborne dust, sulfuric acid, nitric acid, and other tiny particles of aerosol system. In this weather, the throat is easily irritated, and in severe cases, it can even trigger respiratory diseases such as asthma, chronic bronchitis and pneumonia. Inhaling large amounts of airborne particles can lead to respiratory infections.
When these particles and pollutants enter the body, they damage the mucous membranes of the respiratory tract, causing nasal passages to dry out and reducing defenses. Opening windows in this weather can allow "poor" air to flow indoors, increasing the concentration of indoor pollutants, exposing people to adverse conditions and increasing the risk of illness.
Especially for the elderly and children in the family, the possibility of getting sick will be greatly increased due to their weak immunity.
Opening windows in foggy days can actually have some impact as well. The fog may not dissipate quickly, and the inflow into the room will increase the humidity in the room, and the increase in humidity may also trigger some diseases.
If you have to open the windows on smog days, you can open the windows with smaller gaps and use some humidifying spray inside the house. By increasing indoor humidity, dust and microorganisms can more easily settle down without floating in the air, reducing the likelihood of being inhaled by the body.
For some, it may be confusing why it is not appropriate to open windows during the morning and evening rush hours. In fact, the morning and evening rush hours here mainly refer to the rush hours of urban traffic. If you live far from an urban area, in a pleasant environment, or in a rural area, it probably doesn't matter much.
During the morning and evening rush hours in urban areas, vehicle emissions are at their peak. Nowadays, almost every household owns a car, whether it is expensive or affordable, the car is "whirring" on the street and erupting exhaust fumes.
Vehicle exhaust contains a variety of harmful substances, such as carbon monoxide (CO), nitrogen oxides, and other particulate matter, which pose a potential hazard to the environment and human health.
Prolonged exposure to such environments can lead to diseases such as respiratory infections and, in severe cases, affect the heartbeat, increasing the risk of myocardial infarction.
Therefore, opening windows during peak traffic hours does not provide physical and mental health benefits, but may have adverse effects on the body due to inhalation of exhaust emissions.
Especially for those who live on both sides of the street, it is even more important to avoid this time period when opening windows, so as not to enter the indoor air with high concentrations of pollutants.
In such weather, it is not only not recommended to open the windows, but it is also recommended that everyone check whether the doors and windows are closed to ensure that the indoor air is clean.
Another time to pay special attention to is when the window is open in the early morning before dawn and at night.
Everyone may understand that it is not advisable to open the windows at night, and the air outside is cool at night, and if you continue to open the windows, cold air will pour in, increasing the risk of getting sick.
In addition, pollutants in the air have accumulated to a certain extent at night, similar to the time when we are most tired at night after a day of work or study, when outdoor air quality is usually relatively poor.
In environments where smog or viruses are prevalent, introducing poor-quality air indoors can be potentially harmful to the respiratory system. In particular, sleeping with windows open at night makes it easier to expose the body to bad air and increase the risk of disease.
Similarly, there are some problems with opening windows too early in the morning. Before dawn, the temperature is low, and the human body system is still slowly waking up. The sudden arrival of cold air can lead to the occurrence of epidemic diseases such as colds and fevers.
Therefore, it is advisable to try to avoid opening windows too early in the morning. After ventilation during the day, remember to close the doors and windows in time at night, especially in early spring and deep winter, and pay attention to closing the windows at night when the temperature is low to prevent illness. Keeping indoor air fresh can help maintain respiratory health.
The last time to open a window is when it is in bad weather conditions, such as rain, snow, wind and frost.
We usually open windows to let fresh air indoors, but in bad weather, raindrops, snowflakes, etc. can be brought in.
Especially in the summer, when we expect a rainstorm to clean up the heat, we may open the doors and windows to try to let the stuffy air circulate indoors when the storm is coming.
Rain is often accompanied by some wind, which is when raindrops can be blown indoors, scratch wet floors or increase indoor humidity.
In the relatively dry areas of the north, humidity may not cause much inconvenience, but in the south it is different, and we can recall the rainy season in the south, where people not only feel physical discomfort, but even clothing and bedding can become moldy.
It is not suitable to open windows in windy weather, and even in urban environments, it will still carry dust when the wind blows.
Opening windows in such weather may cause the otherwise clean and tidy room to be covered with dust, which not only does not make the indoor air cleaner, but increases the pollution of the indoor air.
Especially in the northwest region, the yellow sand brought by the strong wind is almost unavoidable, and opening the window at this time is like taking a "yellow sand bath" at home.
In some extremely bad weather, it is best to keep the doors and windows closed, and if you have to open the windows, they should also be opened for a short time to avoid leaving them open for a long time.
The ideal time to open your window is when the sun is shining and the air is fresh, especially between 10 a.m. and 4 p.m. During this time period, there is plenty of sunshine and the weather quality is the best, which is perfect for opening windows for ventilation.
The original intention of opening the window is to make the surrounding environment fresher, but also to maintain the health of the body. Therefore, it is not an exaggeration to pay more attention to this detail. The beauty of life is often made up of many tiny details, and only by paying attention to these details can the whole function properly.
Finally, I hope that everyone can live a happy life in a healthy environment. Especially at the turn of the seasons, the invasion of cold air should not be underestimated. While choosing the right time period to open the windows for ventilation, add clothes in time to keep warm, take in more water, live a healthy and happy life, and at the same time be better in study and work. I wish you all good health and a happy life!
