The riding of bicycle has long been advertized as compete form of workout because cycling engrosses the exercise of whole individual body. However, a latest study has warned that riding your cycle in heavy traffic could be actually hazardous for individual heart and it is literally one of the biggest triggers of heart attacks.
The study, which investigated thirty-six pieces of research, assessed different factors triggering heart attacks. After investigating the everyday risks that can carry a heart attack, the researchers found that the final straw escort to heart attack is spending time in traffic as cyclist. The cyclists are most exposed to pollution and are subjecting themselves to another major heart attack trigger
After analyzing the comparative threat posed by each trigger and the population-attributable fraction (PAF) of each, the researchers revealed that exposure to traffic augmented the risk of stimulating a heart attack by seven and half percent, subsequent to bodily exertion with six and half percent. Overall air pollution triggered between five and seven percent of heart attacks.
Drinking alcohol or coffee accounted for five percent. Other risk aspects included negative by 3.9 percent, eating heavy meal by 2.7 percent, anger by 3.1 percent, positive emotions by 2.4 percent and sexual activity by 2.2 percent. The use of cocaine raised the risk of heart attacks by 0.9 percent.
According lead researcher Dr Tim Nawrot from Hasselt University in Diepenbeek Belgium, of the triggers for heart attack considered, cocaine is the presumably to trigger an incident in an individual, but traffic has the greatest population effect because more people are exposed to it. PAFs provide a computation about the amount of disease that would be avoided if the risk was no longer there.
It was hard to unravel the risk factors in the study for certain situations like driving or cycling to work in heavy traffic. Several other aspects are contributing to the overall risk are stress, air pollution, physical exertion, even anger which is another renowned trigger for a heart attack, explained Prof David Spiegelhalter, a risk expert from Cambridge University.
The benefits of exercising outdoors outweighed the risks from air pollution for most individuals, and urged people not to postpone running, walking or cycling in towns and cities, stated Judy O’Sullivan, senior cardiac nurse from the British Heart Foundation. In conclusion, the authors of the study note that in order to meet WHO standards for defending public health, extensive reduce in air pollution will be needed.
