People who live close to airports could be at greater risk of heart attacks, life-threatening heart arrhythmias and strokes, a study shows.
Those who lived in areas where aircraft noise was higher than recommended were found to have stiffer and thicker heart muscles, which were less efficient at pumping blood around the body. This was especially the case for people exposed to higher aircraft noise at night, according to the study by British researchers.
They said that could be due to disturbed sleep and the fact that people are more likely to be at home at night and exposed to the noise, they said.
Dr Gaby Captur, of the University College London Institute of Cardiovascular Science and consultant cardiologist at the Royal Free Hospital in London, told The National that previous animal experiments have shown that mice exposed to simulated aircraft noise experienced higher blood pressure and the release of stress hormones.
This happens in several ways, she said, including activating the body's fight or flight response, which results in short-term circulatory changes such as a raised blood pressure and heart rate, as well as indirectly, by creating annoyance, stress, and the disturbance of sleep.
"These reactions can lead to long-term health outcomes through chronic stress responses, potentially contributing to conditions like hypertension, cardiovascular diseases, and poor sleep, resulting in next-day fatigue among those living near airports," she added.
The study also builds on a previously known link between high levels of aircraft noise with higher blood pressure and obesity in people – both of which were found to account for a significant portion of the link between noise and differences in heart structure and function in the new study.
“Between a quarter and half of the link was attributed to a higher BMI (body mass index) among participants exposed to higher levels of aircraft noise, while between nine per cent to 36 per cent of the link was attributed to these participants having higher blood pressure (this was among those exposed to daytime aircraft noise only)," said first author Dr Cristian Topriceanu, of the UCL Institute of Cardiovascular Science.
“Other factors that could be triggered by the stress response to aircraft noise include impaired sleep, inflammation, and atherosclerosis (build-up of fats, cholesterol and other substances in our arteries).”
The study is observational, so the researchers could not say with certainty that high levels of aircraft noise caused the differences in heart structure and function.
“However, our findings add to a growing body of evidence that aircraft noise can adversely affect heart health and our health more generally,” said senior author Dr Captur.
“Concerted efforts from government and industry are needed to reduce our exposure to aircraft noise and mitigate its impact on the health of millions of people who live close to airports or under flight paths.”
The study, which was published in the Journal of the American College of Cardiology (JACC), studied detailed heart imaging data from 3,635 people who lived close to four major airports in England – Heathrow, Gatwick, Birmingham and Manchester airports.
Around eight per cent lived in an area with high daytime aircraft noise, defined as more than 50 decibels, while three per cent lived in an area with high noise at night, between 11pm and 7am, at 45 decibels on average. The WHO recommends aircraft noise limits of 45 decibels on average during the day and 40 decibels on average at night.
Heart MRIs were carried out at least three years after the readings of aircraft noise were taken. Comparing the hearts of those who lived in areas with higher aircraft noise with those who lived in lower aircraft noise areas, and taking into account factors like age, sex and lifestyle factors, the researchers found that those who still lived in a higher aircraft noise area had about 10-20 per cent worse heart structure and function than their counterparts in these areas who had moved away.
They then looked at a separate sample of 21,360 people who had undergone detailed scans of their heart, concluding that someone with stiffer and thicker heart muscles, like those who live in high aircraft noise areas, are two to four times more likely to suffer a heart attack, abnormal heart rhythm, or stroke.
“We are concerned that the type of abnormalities we saw with night-time aircraft noise might result in increased risk of heart problems and stroke. Aircraft noise at night has been shown to affect sleep quality and this may be an important factor affecting health,” said Professor Anna Hansell from the University of Leicester.
“The role of noise on heart health is currently under investigation. However, there are many established ways to look after your heart. These include eating a healthy and balanced diet, keeping physically active, maintaining a healthy weight, giving up smoking if you smoke, reducing alcohol consumption, keeping conditions such as high blood pressure and diabetes under control, and taking medication including cholesterol-lowering drugs if prescribed by your doctor.”

US PGA Championship in numbers
1 Joost Luiten produced a memorable hole in one at the par-three fourth in the first round.
2 To date, the only two players to win the PGA Championship after winning the week before are Rory McIlroy (2014 WGC-Bridgestone Invitational) and Tiger Woods (2007, WGC-Bridgestone Invitational). Hideki Matsuyama or Chris Stroud could have made it three.
3 Number of seasons without a major for McIlroy, who finished in a tie for 22nd.
4 Louis Oosthuizen has now finished second in all four of the game's major championships.
5 In the fifth hole of the final round, McIlroy holed his longest putt of the week - from 16ft 8in - for birdie.
6 For the sixth successive year, play was disrupted by bad weather with a delay of one hour and 43 minutes on Friday.
7 Seven under par (64) was the best round of the week, shot by Matsuyama and Francesco Molinari on Day 2.
8 Number of shots taken by Jason Day on the 18th hole in round three after a risky recovery shot backfired.
9 Jon Rahm's age in months the last time Phil Mickelson missed the cut in the US PGA, in 1995.
10 Jimmy Walker's opening round as defending champion was a 10-over-par 81.
11 The par-four 11th coincidentally ranked as the 11th hardest hole overall with a scoring average of 4.192.
12 Paul Casey was a combined 12 under par for his first round in this year's majors.
13 The average world ranking of the last 13 PGA winners before this week was 25. Kevin Kisner began the week ranked 25th.
14 The world ranking of Justin Thomas before his victory.
15 Of the top 15 players after 54 holes, only Oosthuizen had previously won a major.
16 The par-four 16th marks the start of Quail Hollow's so-called "Green Mile" of finishing holes, some of the toughest in golf.
17 The first round scoring average of the last 17 major champions was 67.2. Kisner and Thorbjorn Olesen shot 67 on day one at Quail Hollow.
18 For the first time in 18 majors, the eventual winner was over par after round one (Thomas shot 73).
Haemoglobin disorders explained
Thalassaemia is part of a family of genetic conditions affecting the blood known as haemoglobin disorders.
Haemoglobin is a substance in the red blood cells that carries oxygen and a lack of it triggers anemia, leaving patients very weak, short of breath and pale.
The most severe type of the condition is typically inherited when both parents are carriers. Those patients often require regular blood transfusions - about 450 of the UAE's 2,000 thalassaemia patients - though frequent transfusions can lead to too much iron in the body and heart and liver problems.
The condition mainly affects people of Mediterranean, South Asian, South-East Asian and Middle Eastern origin. Saudi Arabia recorded 45,892 cases of carriers between 2004 and 2014.
A World Health Organisation study estimated that globally there are at least 950,000 'new carrier couples' every year and annually there are 1.33 million at-risk pregnancies.

Water waste
In the UAE’s arid climate, small shrubs, bushes and flower beds usually require about six litres of water per square metre, daily. That increases to 12 litres per square metre a day for small trees, and 300 litres for palm trees.
Horticulturists suggest the best time for watering is before 8am or after 6pm, when water won't be dried up by the sun.
A global report published by the Water Resources Institute in August, ranked the UAE 10th out of 164 nations where water supplies are most stretched.
The Emirates is the world’s third largest per capita water consumer after the US and Canada.

Will the pound fall to parity with the dollar?
The idea of pound parity now seems less far-fetched as the risk grows that Britain may split away from the European Union without a deal.
Rupert Harrison, a fund manager at BlackRock, sees the risk of it falling to trade level with the dollar on a no-deal Brexit. The view echoes Morgan Stanley’s recent forecast that the currency can plunge toward $1 (Dh3.67) on such an outcome. That isn’t the majority view yet – a Bloomberg survey this month estimated the pound will slide to $1.10 should the UK exit the bloc without an agreement.
New Prime Minister Boris Johnson has repeatedly said that Britain will leave the EU on the October 31 deadline with or without an agreement, fuelling concern the nation is headed for a disorderly departure and fanning pessimism toward the pound. Sterling has fallen more than 7 per cent in the past three months, the worst performance among major developed-market currencies.
“The pound is at a much lower level now but I still think a no-deal exit would lead to significant volatility and we could be testing parity on a really bad outcome,” said Mr Harrison, who manages more than $10 billion in assets at BlackRock. “We will see this game of chicken continue through August and that’s likely negative for sterling,” he said about the deadlocked Brexit talks.
The pound fell 0.8 per cent to $1.2033 on Friday, its weakest closing level since the 1980s, after a report on the second quarter showed the UK economy shrank for the first time in six years. The data means it is likely the Bank of England will cut interest rates, according to Mizuho Bank.
The BOE said in November that the currency could fall even below $1 in an analysis on possible worst-case Brexit scenarios. Options-based calculations showed around a 6.4 per cent chance of pound-dollar parity in the next one year, markedly higher than 0.2 per cent in early March when prospects of a no-deal outcome were seemingly off the table.
