The noise of planes and railroads can cause very serious damage to the cardiovascular system, which can cause vascular problems in just a few days.
Airplane and railroad noise not only disturbs people, but also causes
Sounding the alarm: How noise hurts the heart

Although it is widely known that noise exposure is associated with deafness, traffic noise from planes, trains and cars has also been positioned as the second major physiological stressor after air pollution in the last decade. Numerous studies have reported linking traffic noise to an increased risk of cardiovascular disease. Mathias Basner, an epidemiologist at the University of Pennsylvania and chairman of the International Commission on the Physiological Effects of Noise, said that while more research shows that noise can have a negative effect on the human body, many people find it noise. He points out that he is unaware of the dangers of.
It is estimated that one-third of people living in Europe and the United States are regularly exposed to unhealthy levels of noise, usually above about 70-80 dB (decibels). Many studies have linked these chronic exposures to environmental noise to an increased risk of cardiovascular disease: 'People living near Frankfurt Airport in Germany have more stroke than those living in quiet places in similar environments. Studies have shown that the risk is 7% higher, and that people living near Zurich Airport in Switzerland have a significantly increased risk of death after being exposed to the noise of night flights. ..
In the graph below, the vertical axis shows the mortality rate, the horizontal axis shows the noise level exposed 2 hours before death, red is female, and green is male. Increased noise levels and increased mortality in both men and women in 'All cardiovascular diseases,' 'Ischemic heart diseases,' 'Myocardial infarction,' and 'Heart failure.' In 'Arrhythmia', it can be seen that the mortality rate of women increases rapidly with increasing noise levels.
Looking at the diagram below, which illustrates the mechanism by which noise causes problems for the body, first of all, 'Transportation noise' interferes with people's activities, sleep, and communication, and makes people feel irritated, cognitive and emotional. Causes a reaction. Next, as 'Stress respose', hormones such as cortisone (precursor of
Specifically, when noise reaches the brain, the auditory cortex, which controls the sound, and the amygdala, which controls the emotional response to it, are activated. As the noise increases, the amygdala unknowingly
These reactions promote the production of harmful oxidants and proteins called cell adhesion molecules in the blood, 'activating' the vascular endothelium and causing inflammation. As a result, dysfunctional vascular endothelium has adverse effects such as hypertension and plaque accumulation, causing or exacerbating obesity, diabetes and cardiovascular disease.
This sequence of reactions occurs not only when exposed to chronic noise, but in human and mouse experiments, exposure to nighttime airplane noise for just a few days causes endothelium problems. I know that. A 2019 study also reported that even healthy subjects had impaired vascular function immediately after being exposed to train noise at night.
While a lot of research data has been accumulated, it is a difficult task to identify the causal relationship between noise and adverse effects on the body, and the fact that 'specific noise is felt differently by people' also makes research difficult. increase. Still, the World Health Organization (WHO) pointed out in a 2018 (PDF file) report that 'every year, more than 1.6 million people living in Western Europe are unable to live a healthy life due to traffic noise.' Awareness of traffic noise and physical damage is growing worldwide.
Measures to protect yourself from traffic noise include changing windows to sound-insulating ones, installing highly sound-insulating curtains, moving your bedroom away from noise sources, and if you can afford it. For example, moving. Also, as a simple method, it is effective to wear earplugs at night. 'If you live in Manhattan, you won't notice how noisy your surroundings are after a while because the noisy conditions are normal, but just because you're psychologically accustomed to it, you're healthy. Is not without its negative effects. '
