The participants were divided into two groups with the first group experiencing persistent loud noise at work for a period of at least three months and the second group working in a low noise environment.
The British Medical Journal reported that those working in noisy environments tended to weigh and smoke more than those who worked in quiet offices and that those under 50 and young male smokers also stood an increased risk.
The risk among workers under the age of 50 was particularly strong with results showing they were between three and four times as likely to have angina or coronary artery disease or to have had a heart attack.
The authors of the study have said: ‘Loud noise day after day may be as strong an external stressor as sudden strong emotion or physical exertion, the effect of which is to prompt various chemical messengers to constrict blood flow through the coronary arteries.’
A spokesperson from the British Heart Foundation has said often individuals working in a noisy environment find it very stressful and this could explain the link between noisy environments and an increased risk of heart disease.
In addition to this stress makes it more likely for people to snack on unhealthy foods, smoke and not participate in the recommended 30 minutes of physical activity each day.
