(NewsMax Health) Noise can kill. New research shows that loud sounds increase the risk of heart attack, high blood pressure, and stroke.
A study published in the European Heart Journal found that long-term exposure to high levels of noise dramatically boosts heart risk. Men exposed to prolonged noise were found to have a whopping 50 percent higher risk of having a heart attack. Women were found to have an even greater risk, almost 300 percent.

“The higher and longer exposure to noise, either environmental or workplace noise, the higher risk for heart attack,” says lead researcher Dr. Stefan Willich. Chronic noise is responsible for about 3 percent of coronary heart disease, according to research by the World Health Organization in the UK.
The one place where someone should not be at risk is a hospital. But a shocking study of noise levels on hospital wards found that noise during shift changes – from clattering carts, loud voices, and other sources – can reach 113 decibels. A typical motorcycle emits 95 decibels.
Such noisiness causes patients to lose sleep, have higher blood pressure, and be more susceptible to strokes, experts say.
Experts believe that noise is deadly because it raises the levels of stress hormones such as cortisol, adrenaline, and noradrenaline in the body. High stress hormone levels have been linked to heart failure, strokes, high blood pressure, and immune problems.
“It has been well documented that high levels of cortisol for long periods increases many health problems,” notes Dr. Marcelle Pick, best-selling author of Is it Me or My Hormones?
Stephen Sinatra, M.D., a renowned cardiologist, says that noise can be the triggering event to a heart attack. “Excessive noise can stimulate the nervous system, which raises heart rate and blood pressure response, thus putting additional strain on the cardiovascular system. If it’s previously vulnerable, a cardiac event could occur.”
Dr. Sinatra notes that too much noise can cause sleep deprivation, another documented cause of heart attacks.
Clinical psychologist Dr. Jack Singer tells Newsmax Health that aside from the physiological effects of prolonged noise exposure, there’s mental damage.
“The psychological strain experienced by people exposed to constant noise includes distraction, lack of focus, and a slowdown of mental processes.”
