If you think mornings are the best time for outdoor exercise, you’re wrong.

Mornings experience the worst air pollution in four Indian cities, according to an analysis of particulate matter (PM) 2.5 data from IndiaSpend’s #Breathe air-quality sensors in Bengaluru, Chennai, Delhi and Mumbai between March 15 to April 15 2016.

Delhi: Best air quality —4 pm

Mornings were the worst time, with PM 2.5 levels reaching as high as 108.16 µg/m3 at 7 am. Air quality gradually improved as the day wore on, registering the cleanest air at 4 pm. (22.84 µg/m3). Pollution levels then picked up through the night.

Delhi topped the list of the world’s most-polluted cities, according to the World Health Organisation (WHO).

Bengaluru: Best air quality–midnight

The worst air was at 7 am, as PM 2.5 concentrations peaked at 61.54 micrograms per cubic metre of air (µg/m3). The air quality improved as the day wore on, worsening by evening at about 5 pm, reaching a late-evening high at 7 pm (57.60 µg/m3). The best air quality was registered around midnight, when PM 2.5 levels fell as low to 40.12 µg/m3.

Chennai: Best air quality—3 pm

The worst air was at 7 am, with PM 2.5 levels (61.54 µg/m3) reached their peak. Levels began to peak over the night and slide during the day, after 7 am. The best air quality was recorded in the afternoon, at 3 pm, with PM 2.5 levels reaching as low as 20.76 µg/m3.

 

Mumbai: Best air quality—5 pm

The worst hour for a Mumbaikar is 8 am, with PM 2.5 levels reaching 48.61 µg/m3; the air started to worsen after 5 am. The best air quality was registered at 5 pm, when PM 2.5 levels were 22.38 µg/m3.

Outdoor air pollution causes 670,000 deaths annually in India, according to a 2014 research paper from the Indian Institute of Management-Ahmedabad.

Air pollution has become a global concern with rising air pollution levels, as outdoor air pollution in cities and rural areas across the world estimated to cause 3.7 million premature deaths in 2012, according to the WHO.

Particulate matter is the term for particles found in the air, including dust, dirt, soot, smoke, and liquid droplets. These are classified according to their diameter. Particles less than 2.5 µm (micrometres) are called PM 2.5. They are approximately 1/30th the average width of a human hair. Particles between 2.5 to 10 µm in diameter are called PM 10.

PM 10 and PM 2.5 include inhalable particles that are small enough to penetrate the thoracic region of the respiratory system. The health effects of inhalable PM are well documented, caused by exposure over both the short-term (hours, days) and long-term (months, years). They include: Respiratory and cardiovascular morbidity such as aggravation of asthma, respiratory symptoms, and an increase in hospital admissions; and mortality from cardiovascular and respiratory diseases and from lung cancer.

There is good evidence of the effects of short-term exposure to PM 10 on respiratory health, but for mortality, and especially as a consequence of long-term exposure, PM 2.5 is a stronger risk factor than the coarse part of PM 10.

There is a close relationship between exposure to high concentrations of small particulates (PM 10 and PM 2.5) and increased mortality and morbidity from cardiovascular/respiratory diseases and cancer, both daily and over time, according to the WHO.

Rapper and music composer Badshah, who is excited about his new reality show “Dil Hai Hindustani 2”, says that rapping is not taken seriously in India as an art form.

Badshah was interacting with the media at the launch of Star Plus channel’s forthcoming reality show along with singer Sunidhi Chauhan on Monday.

Badshah, who has delivered some chart-busting rap songs like “Chull”, “Saturday Saturday” and most recent “Tareefan” is eager to spread awareness about rap as an art form.

Talking about it, he said: “Rapping along with dance and stand-up comedy is not taken seriously as an art form in India and this misconception should change.”

“That is one of the main reasons why I have chosen to be a judge on the show. But apart from that, I’m here to have fun as well, and have a better connection with the audience,” he added.

Talking about the future of the digital platform, Badshah said: “I think it (digital media) is the future, so it’s very important for any production house right now to concentrate on digital media.”

Sunidhi and Badshah will be judging the second season of the reality show “Dil Hai Hindustani”, along with Bollywood singer and composer Pritam.
