Affect the quality of sleep. Studies have shown that noise of 40 ~ 50 decibels will interfere with sleep. 40 decibels of sudden noise can wake up 10% people, and 60 decibels can wake up 70% people. When the continuous noise reaches 70 decibels, it will affect 50% people's sleep.
2. Hazards of air pollution
Air pollutants do harm to human body in many ways, such as respiratory system damage, physiological dysfunction, digestive system disorder, nervous system abnormality, mental decline, cancer, disability and so on. People call the smoke of this disaster "the smoke of killing".
When the concentration of pollutants in the atmosphere is high, it will cause acute pollution poisoning, or aggravate the symptoms, and even kill thousands of people within a few days. In fact, even if the concentration of pollutants in the atmosphere is not high, breathing this polluted air all the year round will cause chronic bronchitis, bronchial asthma, emphysema, lung cancer and other diseases.
