Daily exercise may boost your heart even in polluted areas
London, July 18: People who continue with their regular physical activities may have reduced risk of first and recurrent heart attack even in the areas with moderate-to-high levels of traffic pollution, a new study suggests.
The findings suggests that higher levels of nitrogen dioxide (NO2) -- a pollutant generated by traffic -- were associated with more heart attacks, but the risk was lower among those who were physically active.
"Our study shows that physical activity even during exposure to air pollution, in cities with levels similar to those in Copenhagen, can reduce the risk of heart attack," said lead author Nadine Kubesch from the University of Copenhagen.
For the study, published in Journal of the American Heart Association, the researchers in Denmark, Germany and Spain evaluated outdoor physical activity levels (sports, cycling, walking and gardening) and NO2 exposure in 51,868 adults aged between 50-65 years.
The researchers also compared self-reported activities and lifestyle factors against heart attack and to estimate average NO2 exposure, they used national traffic pollution monitoring data for each participants' address.
They found that moderate cycling for four or more hours per week cut risk for recurrent heart attack by 31 per cent and there was a 58 per cent reduction when all four types of physical activity (together totalling four hours per week or more) were combined, regardless of air quality.
Those who participated in sports had a 15 per cent lower rate of initial heart attacks and there was a nine per cent risk reduction associated with cycling, the researchers said.
Compared to participants with low residential NO2 exposure, those in higher risk areas had a 17 per cent increase risk in first heart attack and 39 per cent for recurrent heart attack, they added.

Inappropriate for MLAs seeking free IPL tickets, says D.K. Suresh
Bengaluru: Bengaluru Milk Union Ltd President D.K. Suresh on Monday said it is inappropriate for MLAs to seek free IPL tickets, adding that those interested in watching matches should pay for them personally.
Speaking to reporters near his residence in Sadashivanagar, he said, “IPL is a commercial tournament and does not represent the country. It is not right for public representatives to focus too much on such matters.”
Referring to the recent controversy during the RCB celebrations, he said, “let us find out who benefited the most from the statements made during the incident.” He also pointed out that BJP MLAs had received IPL tickets as well.
Responding to discussions about relocating the Chinnaswamy Stadium, Suresh said the government has already approved the construction of a new stadium at a location he had proposed.
“I had suggested building a stadium in Surya City and submitted a proposal for it. Bengaluru needs four stadiums in four directions to cater to its growing population and encourage youth participation in sports,” he said.
He noted that apart from Kanteerava Stadium, KSCA, and the Football Stadium, there are limited facilities in the city.
“When I was a Lok Sabha member, I had proposed allocating 100 acres in my constituency at Surya City. The land was later earmarked and the plan approved,” he added.
Suresh said he has discussed the project with Minister Zameer Ahmed Khan, Rajiv Gandhi Housing Corporation Chairman Shivalingegowda, and Anekal MLA Shivanna.
“The Cabinet has now approved the project, and a stadium will be developed on around 50–60 acres,” he said.
He further added that he has requested the Deputy Chief Minister to build another stadium at Shivarama Karanth Layout through the BDA, where 40 acres have been allocated. Plans are also being discussed to develop a well-equipped stadium in Bidadi.
Commending state government's recent bilingual policy move, Suresh said forcing children to learn three languages could affect their comprehension.
“It is a good decision to make two languages compulsory. Learning a third language should be left to the choice of students and parents,” he said.
Responding to criticism from BJP leaders, he said their tendency is to oppose every decision of the government.
“To please their central leadership, they take a pro-Hindi stance. Instead, they should advocate for the adoption of Kannada in all states,” he said.
When asked about the earlier three-language policy under Congress, he said, “the situation is different now. Today, the focus should be on quality learning. Kannada should remain the primary language, while students and parents can choose an additional language.”
