Vehicle Noise Make Easy People suffer a heart attack

Health hazards of air pollution is known to many people. Contains a variety of toxic fumes which when inhaled in the body can cause respiratory problems and high blood pressure. 

But it turns out, noise pollution resulting from vehicle noise can also result in danger, that increase the risk of heart attack.The more noise you listen to the voice traffic, the greater the risk of heart attack. 


Thus the findings of a study in Denmark. The researchers followed more than 50,000 people for nearly 10 years. Researchers found that each increment of traffic noise by 10 decibels increased the risk of heart attack by 12 percent.

"We think the traffic noise at night is very dangerous because it can disturb sleep and increase the concentration of stress hormones in the body. Each time, one can hear the high noise levels and increase the risk of heart attack," said the researcher, Mette Sorenson from the Danish Cancer Society as Myhealthnewsdaily.com reported on Thursday (6/21/2012).

Sorenson and his colleagues found that the relationship between heart attacks and road noise persists even after accounting for the high air pollution near roadways. Researchers estimate as many as 4 percent of all cases of heart attack in Denmark related to traffic noise.Sorenson suggested to choose a bedroom that is not too much to hear the traffic noise. If not, you should protect your home from traffic noise.

"Noise pollution becomes increasingly dangerous as most people do not realize. You might wake up one morning and felt he had to sleep pretty soundly. But when examined in the laboratory, it turns out you have disturbed sleep stages," says Sorenson.

In a study published the journal PLoS ONE, the researchers asked participants to report the residence and the case has ever experienced a heart attack. The participants were also asked about other information such as diet and physical activity. The researchers used the addresses of participants to assess the noise is heard.

The researchers also took into account factors that may influence the risk of heart attack such as gender, smoking habits, intake of fruits and vegetables and body mass index.

"Noise pollution is often not realized the danger to health. Citizens in European countries are generally more concerned about the noise level compared to citizens of the United States," said Sally Lusk from the University of Michigan.

Lusk had done research that shows that a very loud voice heard can cause an increase in blood pressure. Noise pollution tend to be higher in cities, but the noise level depends on the proximity to the highway. Sorensen study found the risk of heart attack increases if the noise heard between 40 to 80 decibels.

"Noise of 10 decibels is quite disturbing conversation. Noise of 85 decibels is the minimum level at which people begin to require hearing protection," said Lusk.
