Noise which is defined as an unwanted sound judged to be unpleasant, loud or disruptive, have been found to not only affect hearing but also the heart adversely. It has been observed that many people are being exposed to excessive noise at work.
A study by the US National Institute for Occupational Safety and Health (NIOSH) reveals that loud noise in the workplace is associated with high blood pressure and high cholesterol.
“Reducing workplace noise levels is critical not just for hearing loss prevention – it may also impact blood pressure and cholesterol;” says Dr. John Howard, director of the NIOSH.
Loud noise is stressful thereby causing an increase in stress hormones such as cortisol, adrenaline and noradrenaline. Over time these hormones could cause high blood pressure, high cholesterol and even stroke.
“It is important that workers be screened regularly for these conditions in the workplace or through a healthcare provider, so interventions can occur. As these conditions are more common among noise-exposed workers, they should especially benefit from these screenings.” – Elizabeth Masterson
