An investigation carried out by Swiss scientists has found that people who are exposed daily to noise levels exceeding 60 decibels, have a 30% higher risk of dying from a heart attack. According to these researchers, residing in a commercial air traffic zone, or less than one hundred meters from a highway, significantly affects health.

The research, carried out by the University of Bern (Switzerland) and published in the journal Epidemiology it has also revealed that the risk increases even more the longer a person remains exposed to noise; thus, after 15 years of exposure, the risk rises to 50% with respect to the general population.

The study indicates that people who live in areas traversed by commercial air traffic routes, or less than a hundred meters away from a highway, are usually exposed to noise levels above 60 decibels.

Spain, a noisy country

Spain is one of the noisiest countries in the world (the second after Japan), and it is estimated that nine million Spaniards frequently suffer noise levels above 65 decibels. In addition to damaging the ear and causing hearing loss, excessive noise is related to adverse health effects such as tachycardia, increased tension, difficulty concentrating, decreased performance, irritability, sleep disorders, depression and acute stress that, In the long term, it could even affect the immune system.

The World Health Organization (WHO) recommends not to exceed 55 decibels during the day and 45 at night.
