We are surrounded by the sounds of the machinery that make our lives comfortable and convenient. The constant thrum of traffic, the thunder of jet engines overhead.
But when we have to listen to these noises for too long or at the wrong time, they can inflict silent and stealthy damage. Increasing evidence shows this damage isn't just to our ears, but to our blood vessels and hearts. Nor is this just a problem for people who live near busy roads or under flight paths. New research suggests noise pollution also causes harm in places such as hospitals.Last week the world's experts gathered in Japan to discuss the latest findings about noise and health. Perhaps most eye-catching was the study that linked noise pollution to your waist size.
In a four-year project published last year, researchers from Karolinska University in Sweden found that the louder the traffic noise to which people in different parts of Stockholm were exposed, the greater the increase in their waist size - there was nearly a centimetre increase for every ten-decibel rise in the noise levels.
