The scientific explanation of haze refers to the haze field of vision when the relative humidity is between 80-90%, which is caused by the mixture of haze and fog. It is called haze weather.

Seven hazards of haze to human body

Harm of haze to lung: haze contains a large number of harmful substances floating in the state of air soluble colloidal substances, which are commonly known as PM2.5 and PM10. These substances float in the air, and people's respiratory function will inhale these harmful substances into the lung, and finally gather in the human alveoli, which can not be excluded. After slowly accumulating, the working ability of alveoli will weaken or even lose its function and necrosis 。 It leads to the weakening of human lung function and the internal pathological changes and even necrosis of the lung.

The harm of haze to respiratory tract: after the harmful substances in haze enter the human body, the first checkpoint is through the human respiratory tract, and finally to the lungs. The human respiratory tract has the function and responsibility to intercept pollutants and harmful substances into the lungs, so most of the harmful substances in the haze we inhale are left in the respiratory tract. These harmful substances have strong adhesion and cause a lot of damage to human respiratory tract.

Harm of haze to the heart: medical research shows that some harmful substances in haze will enter the human blood circulation system after entering the body, and will deposit in the human blood vessels, causing various human heart diseases. Especially for the middle-aged and old people who have already suffered from heart disease, their disease will be greatly aggravated.

Harm of haze to skin: human skin is also breathing at ordinary times. After a large number of harmful substances in haze adhere to the skin, they will be absorbed by the skin partially, which will harm the health of the skin. Because the harmful substances in haze are in the form of aerosols, the adhesion is very strong.

Damage of haze to eyes: when the haze concentration is high, people will feel tired when they are exposed to haze for a long time, and the amount of eye excrement will increase. This is because the haze adheres to the human eye, the fatigue caused by cleaning the eye surface and the result after cleaning.

The harm of haze to the brain: the harm of haze to the brain is rarely mentioned, but it does exist. The harm is mainly reflected in the harm to the nervous system. Some authoritative medical experts and institutions have proposed that when the concentration of haze increases, the harm to human brain will also increase.

Harm of haze to the stomach: there are a lot of harmful substances in haze, which not only adhere to the human skin, but also adhere to the human food. After eating the food with harmful substances, the harmful substances will enter the body with the food, and the stomach will also harm the health of the stomach in the process of digestion.

8. The harm of haze to the reproductive system: at present, there are few studies on the harm of haze to the human reproductive system, but there are also many research results that can be found, proving that in the case of serious haze, it has a great impact on the human reproductive system, especially on the male reproductive capacity.
