New Study Finds Traffic Noise May Raise Blood Pressure
The exact reason why this link exists hasn’t been parsed out, but experts aren’t shocked. “Some of the issue probably has to do with adrenaline in the system and different stimulants that are activated when you’re having noxious stimuli, like noise,” says, a cardiologist at Providence Saint John’s Health Center in Santa Monica, Calif.
noted that in one study, every 5-decibel increase in long-term exposure to aircraft noise was linked to an 8% increased risk of developing hypertension. The review points out that traffic noise is annoying, and that chronic annoyance can lead to chronic stress…which is a risk factor for high blood pressure.
Dr. Andersen agrees. “Chronic noise can lead to chronic stress, and this can lead to a multitude of diseases,” she says.Experts say it’s important to do what you can to lower your exposure to noise. “People should appreciate how noise disturbs our brains and our bodies,” Dr. Weinberg says. “Diminish it with sound barriers—thicker doors, windows, or shades. Use earplugs if necessary.”
