It Turns Out That Noise Increases the Risk of Stroke
Hedva Mager a 74-year-old resident of Kibbutz Mahanayim, lived 25 meters from the local airport. Now she feels that her ears have suffered from the constant noise of planes taking off and landing. Moreover, all people who live in this area have poor hearing.
She also believes that the Minister of the Environment has also noticed the link between noise and health, namely hearing impairment. Consequently, he spearheaded the “Noise reform”, which includes several new rules, which took effect from the middle of the week. Among the rules: a complete ban on the use of blowers designed for cleaning streets, reducing working hours when it is allowed to use noisy tools on construction sites, as well as the use of garden tools, musical instruments, and fireworks.
It is considered that a sound level of 30 decibels is quiet, above 60 decibels is loud, and above 80 decibels is harmful and dangerous to the human ear. According to the data, about 55% of the population of the country is from time to time exposed to noise from 60 to 70 decibels. And another 5% are exposed to noise that exceeds 70 decibels.
“The point is that noise increases stress levels, and stress itself increases the incidence of strokes”- say the cardiology researchers. An experiment in Denmark which recently completed involved 51,000 people aged 50 and over. And it was discovered that 1,880 people who were exposed to traffic noise suffered a stroke. In addition, people aged 65 and over began to suffer from brain disturbances due to noise. Therefore, it was concluded that every 10 decibels of street noise increase the risk of stroke by an average of 27%. “Several studies in the past have shown a link between chronic exposure to noise and an increased risk of heart disease, as well as increased blood pressure. Regardless of the level of air pollution in the atmosphere”- the doctors say. What’s more, sudden noise can also disrupt normal sleep and lead to sleep disturbances.
