Lucknow: If you think that morning walks are the best way to get some fresh air in Lucknow, then think again. After analyzing last week’s data obtained from Plume’s Air quality monitoring App shows that pollution is highest between 4am to 9am with the level of PM 2.5.
The prescribed levels of PM 2.5 in India is 60 micrograms per cubic meters, which is four times the standard set by the World Health Organization (WHO). These levels are categorized as ‘hazardous’, and lead to a shutdown in cities such as Beijing, China.
Morning walkers and Children are the most vulnerable
Morning walkers and children who head to school early in the morning are the most vulnerable to such highly toxic air. According to doctors, it’s best to avoid physical activity early in the mornings or late in the evenings.
Why the pollution is at peak in the morning
“When the temperature is low, pollutants get trapped closer to the ground so there is a high concentration of pollutants in the air we breathe. Strenuous activity at this time leads to people inhaling greater volumes of minute pollutants, which get lodged in the lungs,” said Dr G C Agarwal a physician from Lucknow.
During a conversation with the2is.com weather experts said that pollution levels are the highest early in the morning because of low wind movement, and thus these particles get trapped in the air. Trucks which pass through the city through the night and sweeping activities by workers early in the morning make situations worse.
According to the air quality data obtained from Plume evenings are much much better as the air is a bit clearer during this time of the day. People can shift their work out time from early mornings to evenings.
