Buying a house is a lifetime thing.
There are more and more high-rise houses now.
Choosing a floor is also a headache.
A recent international study shows that
The choice of floor may not be superstitious.
And it really has something to do with life span.
Do you live in Changshou Building?
China Traditional Gold 3 Silver 4
China's choice of floor is generally based on the traditional concept of "gold, three silver and four" decades ago, mostly from a practical point of view:
The first reason is that it is the middle 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 sixth floor, it is the secondary water supply after the frequency conversion pump is pressurized. When the water pressure is good, the 12 floor is easy to be flooded or the toilet is blocked with dirty water. The 34th floor is better, and the water pressure on the 56th floor is insufficient.
Does this view also apply to the tall buildings in today's big cities?
Russian
The seventh 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
Life expectancy is longer than 8 floors, and fewer people get cor pulmonale.
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:
Compared with people who live on lower floors, people who live above the eighth floor have a 22% lower risk of premature death.
Among them, the probability of dying from lung disease is 40% lower, and the probability of dying from serious heart disease is 35% lower.
On the contrary, most people who live in the lower floors die of lung disease and heart disease.
1964 65438+in February, our team was looking for ore in northwest Yunnan. The team consists of eight people, including four guards, each equipped with a submachine gun. One day before departure, a Naxi fellow villager took our car to Weixi. It snowed heavily on the road that day, and the road under the snow was bumpy, so the car would be parked by snow after driving for a while. We often have to come down and push the cart. Just as we got off the bus again, a group of brown things slowly approached us. Just as we were wondering about speculation, Naxi villagers shouted, "Come on, get on the bus. It is simply a group of wolves. " The driver Xiao Wang quickly started the car and stepped on the accelerator ... Unfortunately, the wheel just idled in place and could not move forward at all. At this time, the wolves have approached the car ... everyone can see clearly-eight wolves, all like calves, with their bellies hanging high. Warrior Xiao Wu holds a submachine gun in one hand, and Naxi villagers hold Xiao Wu's gun in the other. "Don't shoot," he said quietly and loudly. "When the shot was fired, they either got under the car or got into the Woods. Wolves will bite tires and surround us, and then wolves will howl and summon more wolves to fight with us. " He went on to say, "The wolf is hungry. They are looking for food. Is there anything to eat in the car? " Almost unanimously, we replied, "Yes." "Then throw it down for them to eat." The villagers seem to be giving orders. I have never experienced such a thing. My mind was blank. Apart from being nervous, my brain seems unable to think. After listening to the villagers, we didn't hesitate. Too many chefs dropped some bacon, ham and very precious dried deer from Lijiang. The wolves are all red-eyed, screaming and jumping at the food, biting and swallowing, and the things that have just been thrown down are eaten up in the blink of an eye. The fellow villagers continued to order: "Drop some more!" The second batch of meat, weighing about 50 kg, flew out the back door again, and only a bag of cigarettes was enough for eight wolves. After eating, the eight wolves sat down neatly and stared at the back door. At this time, several of us are breathing on every screen, our nervous hands are cold sweat, and we can even clearly hear the sound of our own heartbeat ... We don't know how to break through from the wolves. Seeing this situation, the fellow villagers said, "What else? Don't leave anything behind, don't feel bad about these things if you want to save your life! " At this time, besides nervousness, fear and shame ...! As soldiers, we have the responsibility to protect these materials, even at the expense of ourselves. But the reality is that our car is stuck in the snow and can't get out, so we can only be trapped in the car. Our bullets are extremely limited, and once the wolves are summoned, we will be even more helpless. Several of us looked at each other and hesitated for a while, but no one said anything. We reluctantly threw all the meat and a dozen packets of biscuits off the bus! Eight wolves had another big meal. After eating the meat, they also tentatively sniffed the dozen packets of biscuits, but didn't eat them. At this time, I clearly saw that the wolf's stomach was round and his violent and fierce eyes became docile. One of the wolves turned around the car twice, and the other seven wolves did not move. After a while, the wolves took the wolves to the Woods ... The incredible thing happened ... After a while, eight wolves came out of the pine forest with branches in their mouths and put them under the two rear wheels of the car. We can't believe our eyes ... these wolves mean to pad our tires with branches and let our cars drive out of the snow nest. I smiled excitedly ... ha ... ha ... just twice, and another soldier put his hand over my mouth because he was afraid that this sudden laughter would scare the wolf. Then, eight wolves got out of the car together, only to see snow flying on both sides of the car. Tears swirled in my eyes, and I shouted to Xiao Wang, "The wolf is helping us scrape the snow. Start the car quickly. " The car started and slipped again without taking two steps. The wolf repeated what he had just done: "First put the branch under the wheel, and then scrape the snow …". In this way, every time you repeat it, drive forward for a while and repeat it about ten times. For the last time, the car went smoothly for more than a mile, close to the top of the mountain. Further on, it is downhill. At this time, eight wolves were sitting behind the car, one of which was slightly ahead of the other seven wolves. The fellow villager said, "That's just a wolf in front. It was all his idea. " We were so excited that we applauded the wolves and waved to them hard. However, these eight lovely wolves didn't respond to our movements, just looked at us blankly. Then, the first wolf came first, and then the rest slowly walked up the mountain and disappeared into the pine forest ..... After reading it, I couldn't help thinking: even the fiercest wolf knows how to repay. Should we reflect on ourselves? Claiming to be "the primate of all things", should we make this world full of love?
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, Japan
Grounding gas lasts 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 the most common. According to a Japanese statistic, two-story houses account for 54.85% of all houses.
Living on a high floor for a long time, 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.
The thin air in high-rise residential buildings is easy to aggravate the condition of patients with cardiovascular diseases and bronchial diseases.
How many floors is the longevity floor of a building in China?
Urban area: floors 4~5.
Suburb: 1 1 above the building.
Although it doesn't mean that people living on floors 4-5 are all over 100 years old, theoretically, the temperature, lighting, air pollution and noise pollution on floors 4-5 are less, and the objective environment is better, so it can be called "Changshou Building". Why do you say that?
Take 20-story high-rise buildings and urban buildings as examples.
8~ 1 1 building
The so-called smoke layer in environmental science is also a noise collection layer.
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 soot layer in environmental science, and the dust and harmful substances in the air have a process of staying at this height, which is actually due to the "canyon effect":
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. That is, between 8~ 1 1 layers. 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, if it is not protected, it should not belong to Changshou 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 the 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.
1 to the third floor
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 to 3 degrees. In rainy season, 1 to the third floor of a relatively high-rise building, the indoor temperature is chilly.
Wang Xia, a doctor in the Third People's Hospital of Chengdu, said: Most low-rise buildings are cold and humid, which are hotbeds of arthritis and easy to get moldy, leading to beriberi and cardiovascular diseases.
conclusion
The above experts believe that although residential height is only one of the factors affecting health, there is no clear causal relationship, but relatively speaking, floors 4-5 may be more suitable for the housing situation in China:
Lighting is best kept 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.
To sum up: floors 4~5 can be called longevity floors ~
Tip: the floor can be considered from the following aspects.
Give priority to location, consider your own needs and surrounding infrastructure;
The height is up to standard, generally speaking, 3 meters is the best height;
Sufficient light, no need to explain;
Meet the needs, facilitate the elderly to go up and down the stairs at home, and don't live too high.
Which floor would you choose after reading so much?
Instead, choose the housing floor.
First you have to buy a suite!
