Noise pollution disturbs our health and behavior in a number of ways. For example; exposure to noise can damage one of the most vital organs of the body, the ear. Hearing impairment due to noise pollution can either be temporary or permanent. When the sound level crosses the 70dB mark, it becomes noise for the ear. Noise levels above 80 decibels produce damaging effects to the ear. When ear is exposed to extreme loud noise (above 100 decibels) for a considerable period of time, it can cause irreparable damage and lead to permanent hearing loss. Sleep Disturbances is one of the noise pollution effects that can deter your overall well being. Noise can interrupt a good night’s sleep, and when this occurs, the person feels extremely annoyed and uncomfortable. People deprived of uninterrupted sleep show a sharp dip in their energy levels which often results into extreme fatigue. This can considerably decrease a person’s ability to work efficiently. Noise pollution may also lead to mental health problems. Exposure to loud sound can result in elevated stress levels as well as stimulate violent behavior. A constant noise in the vicinity can also trigger headaches, make people tense and anxious, and disturb emotional balance. Another effect of noise pollution is on cardiovascular issues. Studies have shown that high intensity sound cause a dramatic rise in blood pressure as noise levels constrict the arteries, disrupting the blood flow. The heart rate (the number of heartbeats per minute) also increase. These sudden abnormal changes in the blood increase the likelihood of cardiovascular diseases in the long run.
In 1997, the issued a report targeting China's policy towards industrial pollution. The report stated that "hundreds of thousands of premature deaths and incidents of serious respiratory illness have been caused by exposure to industrial air pollution. Seriously contaminated by industrial discharges, many of China's waterways are largely unfit for direct human use". However, the report did acknowledge that environmental regulations and industrial reforms had had some effect. It was determined that continued environmental reforms were likely to have a large effect on reducing industrial pollution.
