Related beetwen traffic with stress and blood pressure
The traffic noise is the largest source of noise within a community. On this subject have conducted a study a group of researchers Swedes. According to their conclusions live close to the avenues with intense traffic can increase the risk of suffering from high blood pressure. A sample of 24. 238 People Swedes showed that those who live near avenues noisy have a highest pressure than those who live in environments more reassured.
Exposure to more than 60 decibels is associated with a high blood pressure among people relatively young and the people of middle age. This is a risk factor for diseases cardiovuscalares as the heart attack. The people of middle-aged who are exposed to a traffic noise high of about 64 decibels (a little higher than normal conversation) were almost twice as likely to have a high blood pressure, compared with those that do not.
Other studies have shown that those who live near airports or working in noisy places have a greater risk of having high blood pressure. The theory is that the noise works for the body as a sign of stressful situation. Therefore, a chronic exposure can cause an increase in the long term of the production of the stress hormone, the pace of the heart and blood pressure. In addition, the noise can be damaging for the rest correct.
Of all forms this is not a sufficient proof that the traffic near cause a blood pressure higher. According to the researchers only is a factor to take into account. Ensures that still need more studies to know really what the effect of the noise pollution on our health.
