Choosing a floor also gives many people a headache.
A recent international study shows that,
The choice of floor may really be related to life!
What floor do you live on?
Let's see if you live in Changshou Building ~

Li Ming, an expert in environmental protection in Chengdu.
Wang Xia, a doctor at the Third People's Hospital of Chengdu, said.
China Tradition: Gold 3 Silver 4
China chose the floor, and the traditional concept decades ago generally followed the principle of "three golds, four silvers", mostly considering practicality.
First, because it is an intermediate layer, the top layer is sunny, the first layer is dirty, the second layer is not as good as the third layer, and the third layer is the best. Mosquitoes can't fly and climb stairs easily. Second, in terms of water supply, generally speaking, floors 1~6 are municipal water supply. Above the 6th floor is the secondary water supply after pressurization by the frequency conversion pump. Under the condition of good water pressure, the floors of 1 and 2 are prone to flooding or toilet blockage and return to dirty water, the floors 3 and 4 are better, and the water pressure on the floors 5 and 6 is insufficient.
However, does this view also apply to the tall buildings in today's big cities? Let's take a look at the longevity floor abroad.
Russian: The eighth floor is the golden floor.
Russia's "Science and Life" magazine once published an article saying that although the lower floor is close to the ground and convenient for contact with the outside world, there are problems such as high humidity and poor air circulation. The eighth floor is the golden floor in their eyes, because this floor is quiet and not affected by noise.
Switzerland: the life span is longer than 8 floors.
A study by the University of Bern in Switzerland was published in the European Journal of Epidemiology, covering Switzerland10.5 million people. The researchers found that people who live above the eighth floor have a 22% lower risk of premature death, including a 40% lower risk of dying of lung disease and a 35% lower risk of dying of serious heart disease. Researchers believe that the reason is that high-rise residential buildings have less air pollution and relatively less noise than low-rise residential buildings.
America and Japan: Grounding gas will last longer.
In the United States, under the influence of "anti-urbanization" (the return of urban population to villages and small towns), independent low-rise housing is dominant.
Even in densely populated Japan, two-story and three-story houses are common. According to a Japanese statistic, two-story houses account for 54.85% of all houses.
They believe that living on high floors for a long time and being far from the ground will lead to psychological depression. People don't like going out, which is not conducive to neighborhood communication, and gradually makes people become "home" and withdrawn. Moreover, the air in high-rise residential buildings is relatively thin, which is easy to aggravate the condition of patients with cardiovascular diseases and bronchial diseases.
In China, how many floors is the "longevity building" of a building?
Urban area: floors 4~5.
Suburb: 1 1 above the building.
Although not all people living on floors 4-5 are over 100 years old, floors 4-5 have better temperature and lighting, less air pollution and noise pollution, and a better objective environment, so they can be called "longevity floors". Why do you say that?
Take a 20-story high-rise building in the city as an example. ※
1~3 layer
Cold and damp are harmful to health, and it is better to have raised floors.
As the saying goes, "it's too cold on the floor", the indoor temperature of low-rise residential buildings differs from that of high-rise residential buildings by 1~3 degrees. In rainy season, the indoor temperature of 1 ~ 3 floor of a relatively high-rise building is chilly.
Wang Xia, a physician in the Third People's Hospital of Chengdu, said: Most low-rise buildings have poor lighting, but cold and damp are hotbeds of arthritis, and it is easy to get moldy and lead to beriberi and cardiovascular diseases.
8~ 1 1 building
Dust layer and noise collection layer in environmental science
Feng Zongrong, a professor of real estate at Sichuan University, believes that "the higher you live, the longer you live."
The 8~ 1 1 layer is the so-called smoke layer in environmental science, and the dust and harmful substances in the air have a process of staying at this height. Under the action of street wind, the airflow containing dust does not move smoothly, but "wanders" up and down in a certain interval between tall buildings.
The pollutants near the ground rise to a certain height with the airflow, and then dissipate downward or horizontally. This "height" is about 30 meters, between 8~ 1 1 floor. At present, there is a "high-density area of pollutants" in the middle of high-rise residential buildings in many communities.
Therefore, in the urban area, more than 8 floors, if not protected, should not belong to the "longevity building." Of course, if you are far away from the city and the surrounding trees are lush, you can live relatively high and see farther ~
6~20 floors
Depending on the environment, the noise is relatively high.
Regarding noise pollution, Li Ming, an environmental expert in Chengdu, said, take a 20-story building as an example. If the building is paved with roads in all directions and lives on the 20th floor of 15, the noise from the road will be received even if it is several kilometers away.
In addition, if the noise source around the building is only a road in front, then the residents living on the middle floor 6~ 15 are not so lucky, and the noise can easily enter the house directly. High-rise buildings are relatively far away from noise, and it is quieter below the sixth floor, because trees or sound insulation screens on both sides of the road will help low-rise residents block out some noise.
conclusion
The above experts said that although the residential height is only one of the factors affecting health, there is no clear causal relationship, but relatively speaking, the 4-5 floors may be more suitable for the housing situation in China.
Because the 4~5 floors have better lighting and stay away from the cold; Low air humidity is beneficial to human health; If you climb the stairs home every day, you can also exercise your heart and lung function, and you won't be too tired. So floors 4~5 can be called "longevity floors" ~
This article is for everyone to see.
Blessed are the friends who live on the 4th-5th floor.
But we should also pay attention to health care;
It doesn't matter if you don't have friends who live on the fourth floor to the fifth floor.
The right to health is in your own hands!
No matter where you live,
Everyone should develop good health care habits,
This is the real secret of longevity!
Can I buy the ground floor? This problem has troubled many property buyers, but in fact, the correct answer to the question is to buy! Of course, this does not mean that all the bottom floors can be bought, only in a few cases. Before you make a choice, first understand the advantages and disadvantages of the subfloor, as well as the precautions when buying.
What are the advantages and disadvantages of the bottom layer?
superiority
1, cheap
Houses on the ground floor are cheaper than houses on other floors, and sometimes gardens are given away, so the space utilization rate will be greatly improved.
2. Convenient life
Living on the ground floor, you can go out by opening the door and turning a corner. Life is so convenient, isn't it fast? And living on the ground floor, closer to the natural environment, is also conducive to health.
3. Easy to escape
The ground floor is close to the ground, which makes it easier to escape in case of an accident and has a high safety factor.
disadvantaged
1, poor lighting and ventilation
If there are many obstructions around the house, it will affect the lighting and ventilation effect of the ground floor.
2, easy to be stolen
The first floor is easy for thieves to patronize. After all, even if you run in through the window, you don't worry about falling your leg.
The noise pollution is very serious.
If the house faces the street, the noise and cars will annoy the residents at the bottom.
