Some merchants say that sleeping on tiles is not good, what is so bad, I have been like this for dec

Tiles are really bad.

Li Zengkuan, director of the Department of Material Radiation Safety Inspection and Certification of China Building Materials Inspection and Certification Center, told reporters that there are two main aspects of radiation to consumers of ceramic tiles: in vivo radiation and in vitro radiation. Radiation in vivo mainly refers to the radiation of radon to the human body, radon is a radioactive natural substance, colorless and odorless, with the characteristics of easy diffusion, soluble in water, and very soluble in fat.

The radon emitted from ceramic tiles is mainly a chemical called radium, which is contained in the raw materials of ceramic tiles, such as slag, as well as zircon sand as an emulsifier (its main role is to improve the finish and wear resistance of tiles).

After radium decays to produce radon, radon enters the human respiratory tract, before decay, part of it can still be exhaled with respiratory activities, and the other part is adhered to the respiratory tract and absorbed by the human body, in addition to mainly inhaling from the respiratory tract, a small number can also enter the digestive tract with the swallowing action in the throat, causing radiation to people in the body and destroying the human respiratory system. Zhang Qi, deputy secretary-general of the Indoor Environmental Protection Committee of the Beijing Building Decoration Association, also said that because radon has a high "affinity" for human fat, if the human body inhales a large amount of radon for a long time, it will also affect the human nervous system, making people feel sluggish and drowsy. If the human body inhales large amounts of radon for a long time, its radiation inside the body will cause abnormal changes in the cells, which can lead to lung cancer.

Radiation will destroy the lymphocytes of the human body, so that people's immunity is reduced, and the external radiation of tiles to people is mainly due to the chemical elements contained in raw materials, such as radium, thorium and other decay produced by rays. The rays are very penetrating. It will penetrate the human body and collide with the cells in the body, which will destroy the lymphocytes of the human body, thereby reducing the person's immunity.

The range of the ray is shorter, so it has a greater impact on children, but because its penetrating power is relatively weak, a book can block its penetrating power.

Let's see for yourself, this is only part of it.

Sleep directly on the tiles? It's too cold, it hurts your bones.

I don't feel good about sleeping on the tiles, it's hard, it's cold, it's not good for the joints.

The main thing is that the humidity is heavy, and often sleeping on the floor will not be good for the joints, and it doesn't matter if you are young, but it is best not to be old, it is easy to cause rheumatoid and arthritis. In addition, there are a large number of dust mites on the ground that are invisible to the naked eye, and sticking to the body can cause itching and allergies.

You may get rheumatism, the floor is cold, and your stomach is cold, but you don't feel it at the time, and the longer you sleep, the worse the symptoms will become. It can also cause pain in the lower back and legs due to the cold, and can suffer from arthritis, cervical spondylosis, and herniated discs.
