Noise at work hammers heart

"Get a hearing aid!".. "Hugh?.. Get marmalade?  What are you saying?"

We normally associate too much exposure to noise with hearing loss.. add cardiovascular disease to that.

Studies are now showing a clear relationship between chronic exposure to noise in the workplace and  increased risk of coronary heart disease, high blood pressure, chest pain, and heart attack.

The response is greater in smokers.

How does noise do this?  Research did not find increases in fats or cholesterol in the blood, but did find chronic noise exposure increased blood pressure, specifically diastolic blood pressure without increased systolic pressure, called independent diastolic hypertension (IDH).  Systolic pressure is measured when the heart pumps, diastolic is between beats when the heart relaxes.

It's thought that chronic noise exposure is stressful, resulting in constricting blood vessels.
