What floor is the best in the house?

Let's talk about the low floors that are generally not favored by buyers, especially young buyers. From the first floor to the third floor, people generally live under the canopy, close to the ground, and often hear the sound of branches knocking on the window; To be psychologically comfortable, this is the best place; Keep in touch with the outside world and don't look down on people. However, the life close to the ground also has some shortcomings: the first to third floors are close to the ground, although psychologically comfortable, but the low-level air circulation is slow, there are many shadows, the humidity is high, and the pollution in the poorly ventilated building is also serious.

When it comes to high-rise buildings with strong natural wind, many residents often feel that the natural wind is sometimes too strong (especially in windy areas and spring and summer seasons), and the air on the roof is not as fresh as expected. Chimneys of all sizes almost surround the city, and it is inevitable that harmful substances will gather more than 30 meters. The 8- 1 1 layer is the so-called smoke layer in environmental science, and the dust and harmful substances in the air stay at this height. In fact, due to the "canyon effect" ("canyon effect" refers to the surrounding bus trunk roads or factories, as well as high-rise houses), under the action of street wind, the airflow containing dust does not move smoothly, but somewhere between high-rise 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. Dust will stay between the 8- 1 1 floors of these buildings. In this process, residents will "share the same fate with the dust" for a period of time, and then "kiss goodbye". Moreover, it happens to be a noisy space. Many consumers think that living in a tall building can "get away from the hubbub". Who would have thought it would be better to listen to the noise of vehicles on the first floor than on the 8- 14 floor?

Considering all factors, it is best not to exceed six floors for small and high-rise buildings. The sixth floor is the best, followed by the fifth, fourth, second, third, seventh, eighth and ninth floors ... The accumulation of heavy metals such as lead on the first floor (generally suspended below 2 meters) is actually not good for the elderly.
