Loud noise exposure may lead to high blood pressure

There are many causes to hypertension. Some of the most reported ones are those associated with food choices and eating habits. But did you know that noise exposure can put you at risk of developing high blood pressure?

Loud noises are caused by many things such as operating a machine or a motor engine, driving through a busy traffic, and living by an airport or train tracks. Studies have shown that exposure to noise raises blood pressure and increases the risk of developing cardiovascular disease. This is because loud noises are associated with chronic high levels of stress hormones such as cortisol, adrenaline, and noradrenaline. These hormones are associated with hypertension, stroke, heart flutter, heart failure and problems with the immune system. A noise level 55 decibels or above can put your health at risk.

Residents living close to busy roads, under flight paths or near industrial parks may be particularly affected by loud noises. Some airports, like Vancouver's YVR, offer a real-time noise levels tracking tool.
