Traffic, airplane noise is reportedly a ‘silent killer’

The noise of the city is a real killer.

The dine of an urban environment – linked to long-term hearing issues – can lead to a series of heart problems, which can come as a threat to residents right behind air pollution, a report said is.

Over the past ten years, a growing body of evidence has revealed trauma noise exposure, which may include stroke and nocturnal mortality, The Atlantic reported Sunday.

The 2018 study in noise and health examined health data of more than 1 million people, the report said, which found that for people living near Frankfurt Airport in Germany, 7 percent is higher, which That is more than people living in quiet neighborhoods.

An analysis published in the European Heart Journal examined approximately 25,000 cardiac deaths between 2000 and 2015 and found that people who live near Zurich’s airport, especially women, have nighttime mortality after airplane flyovers. There was a significant increase in

The World Health Organization calculated the number of premature deaths, which were directly related to noise exposure, and in 2018 found that Western Europeans collectively are losing more than 1.6 million healthy lives as a result of traffic dines.

Matthias Besner, a University of Pennsylvania psychiatrist and epidemiologist and chairman of the International Commission on the Biological Effects of Mathematics, said the research is “really coming together and presenting a picture of the problem,” which his co-workers call a “silent killer” . ”

Scientists have begun to explore how noise affects the heart and falls under the inner layer of the endothelium, blood vessels, and arteries. When there is loud noise in the brain, especially during sleep, the amygdala turns on its stress response, which fills the body with hormones such as adrenaline and cortisol, even when the person is not aware of the noise.

It increases blood pressure and leads to inflammation in the blood vessels, which affects blood flow and negatively affects other processes that cause cardiovascular diseases such as hypertension, diabetes, obesity and plaque formation in the arteries. Can contribute to

Scientists said that the effect is not necessary due to prolonged exposure to noise and it can also affect those who are not victims of heart problems. Studies conducted on people and mice have shown that the inner lining of blood vessels and arteries do not function properly after a few days of exposure to nighttime airplane noise, which is reported in the report.

In addition, a 2019 study published in Basic Research in Cardiology found healthy adults who were subjected to train noise while sleeping impaired their blood-vessel function almost immediately.

According to the outlet, Thomas Munzel, a cardiologist at the University Medical Center Mainz who investigated the effects of Hart’s noise, said, “We were surprised that young people had endothelial dysfunction after hearing these sounds for just one night.”

“We always thought it was something that takes years to develop.”

To overcome the health effects of noise, people should ensure that their bedrooms are as quiet as possible – they can hang noise-reducing curtains, update their windows and wear ear plugs at night. Besner said that even if people are not frightened by the noise themselves, they should take steps to reduce its risk.

“If you’re living in Manhattan, you won’t notice how loud it is after a while, because it’s normal,” Besner told the outlet.

“But if you are used to it psychologically, it does not mean that it does not have negative health consequences.”
