Navi Mumbai: High particulate air pollution levels have raised health concerns, particularly for those who exercise outdoors early in the morning. October 17, Sanpada recorded a PM2.5 sub-index of 448 and a PM10 sub-index of 500 around 4 am, highlighting the potential risks of exposure to polluted air.

According to the Central Pollution Control Board (CPCB) dashboard, Navi Mumbai’s overall Air Quality Index (AQI) stood at 136 at 5 pm, while Sanpada recorded 156, Nerul 165 and Mahape 157.

Pulmonologist Dr Prashant Chhajed stated, “Fine particulate Matter (PM) can penetrate deep into the lungs, aggravating respiratory conditions and increasing cardiovascular risks. Fine particles such as PM2.5 go deep into the lungs and can trigger asthma and flare-up lung diseases, chest infections, and even heart attacks and strokes in people who are at risk.”

Chhajed advised children, senior citizens, pregnant women, and people with heart or lung conditions to avoid outdoor exercise on highly polluted days. “Patients with lung diseases, small children, and people with breathing complaints should check AQI before stepping out and wear a well-fitted N95 mask. Patients using inhalers should continue their medication and seek medical attention if symptoms worsen,” Chhajed added.

Dr Sachin Bheda and a regular jogger also expressed concern over the smog observed before sunrise. He suggested that construction activity and industrial emissions could be contributing factors. “During wee hours, the pollution levels are very high; with sunrise, the PM levels get subdued and the smog as well. Therefore, it is safer to exercise or jog after sunrise,” Dr. Bheda stated.

Residents unable to delay outdoor activities should cover their nose and mouth with a mask.

Rajesh Mhatre, Medical Officer of Health at the Navi Mumbai Municipal Corporation (NMMC), urged residents, especially those with allergies, to wear masks outdoors. He also advised inhaler users to carry their medication and stressed the importance of preventive measures. The readings highlight the need for continuous pollution monitoring, public awareness, and coordinated efforts to improve air quality and protect residents’ health.
