Living under a noisy flight path or near a busy road isn’t just annoying, a study suggests it can increase your risk of heart attack.
Scientists from New Jersey found that heart attack rates were 72% higher in areas of the US state with the highest levels of noise pollution.
They estimate that one in 20 heart attacks can be attributed to traffic noise, which previous studies have suggested can disrupt sleep and cause chronic stress.
The study was presented today at the American College of Cardiology’s annual scientific session in Washington, DC.
The study’s lead author, Professor Abel Moreyra, a cardiologist at Rutgers Robert Wood Johnson School of Medicine, said noise pollution should be viewed as a risk factor for heart disease, just like blood pressure and diet.
“As cardiologists, we’re used to thinking about many traditional risk factors, such as smoking, hypertension or diabetes,” he said.
“This study and others suggest that we may need to start considering air and noise pollution as additional risk factors for cardiovascular disease.”
A study by New Jersey experts found that the risk of heart attack was 72% higher in areas with high noise, such as caused by low-flying airplanes.
In the study, researchers compared state data on heart attack registries in 2018 with government data on traffic noise, broken down by geography, over the same time period.
They divided approximately 16,000 heart attack patients by the average noise level they were exposed to over a 24-hour period.
Sound level examples
10 decibels: Breath.
20 decibels: A whisper was heard a few meters away; light wind in the trees.
30 decibels: A humble speech.
40 decibels: A library, a refrigerator, a quiet street at night.
50 decibels† Light rain, washing machine.
60 decibels: Normal conversation.
70 decibels† Crowded street, vacuum cleaner.
80 decibels: Alarm clock, factory, noisy restaurant.
90 decibels: Subway, lawnmower, alarm.
100 decibels: Drill, chainsaw, motorcycle.
110 decibels: Loud concert, club.
120 decibels: The siren of an emergency vehicle taking off from the plane was heard from about 300 meters away.
130 decibels† Pneumatic hammer, air tool. Human response: pain.
140 decibels: It was heard that a plane took off from about 50 meters.
Persons exposed to an average of 65 decibels or more of noise during the day were counted in a noise-exposed area.
That equates to someone who is constantly smiling in the same room as you, day and night.
The researchers found that heart attack rates were 72% higher in areas with noise pollution exceeding the average daily decibel level.
These areas had 3,336 heart attacks per 100,000 people, while in quieter areas 1,938 heart attacks per 100,000 people.
The study was observational, meaning it did not explore how noise pollution might lead to heart attacks.
However, Professor Moreyra said it has previously been linked to stress, sleep disturbances and emotional distress such as anxiety and depression, which can affect cardiovascular health.
Chronic stress, in particular, is linked to inflammation of the arteries and the resulting risk of heart disease, he added.
Professor Moreyra acknowledged that traffic pollution, which has a stronger link to heart problems, may also have played a role.
Small toxic particles in the air can penetrate deep into the lungs and cause a variety of problems, including inflammation.
Other limitations of the study are that it did not take into account other demographic and socioeconomic heart attack patients, which may have affected the noise levels or risks to which people at work, such as construction work, are exposed.
Professor Moreyra said future studies could explore these areas to better determine the precise risk of noise pollution for heart health.
In the UK, around 100,000 people are hospitalized each year after a heart attack – the equivalent of one hospitalization every five minutes.
This figure is much higher in the United States, with 850,000 heart attacks per year.
According to the Ministry of Environment, Food and Rural Affairs’ 2019 report, around 886,000 people in the UK are exposed to noise levels above 65 decibels per day.
HOW ACOUSTIC POLLUTION AFFECTS YOUR HEALTH
Noise not only causes discomfort, but can also disrupt sleep, damage hearing and seriously endanger people’s health.
The World Health Organization recommends a guide level of 30 dB LAeq for uninterrupted sleep and a daytime level of 50 dB for external noise levels to avoid “moderate irritation” of people.
Physiological effects of sound exposure include constriction of blood vessels, contraction of muscles, increased heart rate and blood pressure, and changes in stomach and abdominal movements.
Numerous reports have made direct links between transportation noise and heart health:
- A 2015 study by Barts and the London School of Medicine found that people surrounded by more than 60 dB of traffic noise during the day were 4% more likely to die than people with a noise level of 55 dB, roughly loud. speech.
- In the first study of its kind, researchers in Denmark in 2011 found that for every ten decibels of noise increased, the risk of stroke increased by 14%. The risk increased by 27% in people over 65 years of age.
- Research published this year, which followed thousands of people living in Amsterdam for four years, found that exposure to traffic noise above 70 decibels (db) increased the risk of depression by 65%.
The World Health Organization has calculated that at least 1 million years of healthy life are lost every year in Western European countries due to environmental noise.
