Living in a noisy city? It can disrupt your heartbeat, cause cardiac disease

Here’s another reason to avoid noisy cities. Constant change in noise can play havoc with your heart rhythm and lead to serious heart problems.

Scientists are warning that fluctuating noises from busy city streets and town centres disturb normal heart rhythms and could trigger serious cardiac problems. Researchers from Nottingham Trent University in the UK found that constant changes in noise — even at low levels — had an immediate and disruptive effect on normal heart rates. The findings show that everyday surroundings could have wider implications for long-term health, researchers said. It is especially pertinent in India where noise pollution exceeds permissible limits in seven cities.

For the study published in the journal Information Fusion, shoppers were asked to wear mobile body sensors to monitor their heart rates as they moved about Nottingham city centre for 45 minutes. “We found that rapid changes in noise resulted in rapid disturbance to the normal rhythm of participants’ hearts,” said Eiman Kanjo from Nottingham Trent.

“If this pattern is repeated regularly then there is a danger it might lead to cardiovascular problems,” Kanjo said. The study is the first to use sensors to model the short-term impact that city environments can have upon the human body, the ‘Telegraph’ reported. The researchers also found that air pressure had an effect on heart rate as well as body temperature.

Environmental data including noise, air pressure and light levels were compared to data from participants relating to heart rate, body temperature and movement and changes in the electrodermal activities of the skin. None of the participants had heart problems, but the researchers say it would be useful to study whether people with heart conditions suffered a greater impact.
