Environmental noise-induced and health disorders

Environmental noise-induced cardiovascular, metabolic and mental health disorders: a brief review, is a study published on the Environmental science and pollution research international. The study researchers take an in-depth retrospective on this puzzling issue: "Environmental noise is a pervasive pollutant that is one of the greatest environmental threats to mental, physiological and psychological well-being and has a significant global health burden associated with it.

Many epidemiological studies indicate long-term relationship of noise pollution with wide range of metabolic, cardio-vascular and respiratory disorders and diseases. The goal of this study was to thoroughly analyze available literature on public health implications and various underlying biological mechanisms associated with ambient noise exposure, taking into account both objective and subjective measures of noise exposure.

A search of literature for review on environmental noise and associated cardiovascular, mental health and metabolic implications on human health was done using Web of Science, Google Scholar and PubMed databases. Experimental studies indicate that noise exposure leads to endocrine effects, increased incidence of diabetes, impairment of cognitive performance, sleep disturbance and annoyance.

Epidemiological evidence indicates that high levels of noise, particularly at night, may cause arterial hypertension and endothelial dysfunction due to higher level of stress hormones and oxidative stress. An increased incidence of cardio-vascular diseases like myocardial infarction, heart rate, ischemic heart disease, stroke and heart failure is associated with noise-induced mental stress.

Furthermore, psychological and mental health issues like anxiety and depression are also related with exposure to noise pollution. This article summarizes a comprehensive and systematic knowledge established in recent noise research with the spotlight on cardiovascular, metabolic and mental health disorders of environmental noise, providing unique understanding into underlying mechanisms." Noise pollution can cause psychological damage, pressure and stress to people who are continuously subjected to it.

The causes of noise pollution can be factories, construction sites, airports, highways. The effects of noise on humans are manifold. The sensitivity of the human ear to sound is between 20 and 20,000 Hz, but not all frequencies are perceived with the same intensity: in fact, the human ear exhibits better sensitivity to medium frequencies, while it gets worse for high-pitched sounds and for serious sounds.

The measurement is performed with instruments suitable for measuring sound, and these detect the intensity of the sound
