Environmental noise represents a health problem for at least one in five citizens of the European Union. Noise exposure leads to the development of arterial hypertension, myocardial infarction, stroke, and obesity. Given the limited information on noise exposure and noise effects on humans in the Republic of Serbia, the overall objective of NOXYCARD is to collect environmental noise levels data; to identify long-term and short-term noise effects on the cardiovascular system; and to evaluate the levels of blood stress hormones, oxidative stress, and inflammation in individuals with normal body weight and individuals with obesity.
