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.

MP: 7-year-old girl raped and murdered; minor relative detained
Barwani (MP), Jan 28 (PTI) Police on Wednesday detained a 17-year-old relative of a seven-year-old girl in Barwani district of Madhya Pradesh for allegedly raping her and killing her by throwing her into a canal, a police official said.
Superintendent of Police Jagdish Dawar told reporters that the body of the child was recovered from the Indira Sagar Canal on January 26, following information from residents of a village in the Rajpur police station area of the district.
He said the post-mortem report concluded severe injuries to the girl’s private parts and attributed her death to drowning.
Dawar said a 17-year-old boy, a close relative of the girl, has been detained in connection with the rape-murder.
The teenager told the police that he kidnapped the girl from her home on the night of January 25 while her family members were asleep, took her to a nearby canal and raped her, according to the official.
When the girl started screaming during the sexual assault, the minor boy allegedly threw her into the canal, with the intention of killing her. The child drowned in the water body, the official said.
The detained minor will be produced in a juvenile court.
A case has been registered under the Protection of Children from Sexual Offences Act and the Bharatiya Nyaya Sanhita, and an investigation is underway, he added.
