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.

US VP JD Vance says Lebanon not part of ceasefire, calls it ‘misunderstanding’
Budapest/Washington: US Vice President J D Vance has said that Lebanon was never included in the ceasefire understanding with Iran, describing the confusion as a “legitimate misunderstanding”.
Speaking to reporters before departing from Hungary, Vance said, “I think the Iranians thought that the ceasefire included Lebanon and it just didn’t. We never made that promise.”
He stressed that the United States had not included Lebanon in the scope of the ceasefire at any stage.
His remarks come amid continued Israeli strikes in Lebanon, where more than 200 people were reported killed, even as ceasefire talks between Iran and the US move forward.
Vance said Israel had “offered … to check themselves a little bit in Lebanon because they want to make sure that our negotiation is successful”.
He warned that if Iran allows the situation in Lebanon to affect the negotiations, it could derail the talks.
“If Iran wants to let this negotiation fall apart in a conflict where they were getting hammered over Lebanon, which has nothing to do with them and which the United States never once said was part of the ceasefire, that’s ultimately their choice,” he said.
