The air quality in major Indian cities has plummeted to “very poor” levels, with particulate matter being the dominant pollutant. As usual, after Diwali celebrations, Delhi-NCR is leading the way with the smog hitting early today morning. But it is crucial to understand what PM2.5 and PM10 (particulate matter) refer to and deal with the problem accordingly. Particulate matter, refers to coarse inhalable particles in the air, which cause dangerous health issues over prolonged exposure. The side effects of this pollutant's varieties affect the lungs and cause respiratory and cardiovascular issues like tightening of the chest, difficulty breathing, and sore throat coupled with watery eyes and dry skin.
According to the most recent air quality report, the current real-time PM2.5 level in India is 81 per cubic meter and PM10 level is 142 per cubic meter, which puts the air quality in the poor level or hazardous category. If you are experiencing severe side effects or specific health concerns, please contact a doctor for medical advice.
Wearing a mask outdoors is mandatory, namely an N95 or N99 (respirators are not resistant to oil-based particles, which means that the mask filters particulate matter effectively) mask while stepping outside.
Note: Surgical masks are ineffective against PM10 as well as PM2.5 levels. Please use replaceable filters in the masks, as after repeated usage, the mask filter needs to be changed, replaced, and washed in plain liquid soap and water to maintain proper mask hygiene to avoid mask acne and skin breakouts.
The most vulnerable groups during high PM10 levels are children and the elderly, as they have undeveloped lungs and compromised immunity, respectively. People with special immunocompromised conditions like asthma or cardiovascular issues should keep their medication handy. The most important aspect is to have an emergency action plan and take all necessary precautions.
There are a myriad of pollution-fighting foods that can mitigate the effects of air pollution. In the food system, there are various fruits and seeds that can mitigate the risk of developing the side effects of prolonged exposure to air pollution.
They are as follows:
The challenge of unhealthy air quality index (AQI) demands immediate and decisive action to protect your family. While systemic changes are crucial, the most effective first line of defense lies in the steps you take today.
Don't wait for the skies to clear naturally; empower yourself with these protective measures. And diligently implement them to safeguard your long-term health and well-being and those of your loved ones from the invisible threat of air pollution by creating a safe and breathable environment for your family.

Written by Sambhav KumarAccording to a Centre for Science and Environment (CSE) report, the average PM2.5 concentration during the week before Diwali stood at 236 micrograms per cubic metre, almost double the 120 ug/m3 recorded in 2025. It was also the highest pre-Diwali average in three years.
The transport sector is expected to be the largest contributor to pollution on Wednesday, while the impact of stubble burning is anticipated to increase on Thursday, potentially worsening air quality further over the next few days, according to Indian Institute of Tropical Meteorology models.
Air pollution in Delhi-NCR has worsened during the onset of winter (from October to mid-November) this year. This has been revealed in a new analysis by the Centre for Science and Environment or CSE, an organisation that monitors environmental issues.
All 10 cities in the ranking fall under the 'Hazardous' category, with Bathinda recording the highest AQI, followed by Rewari and Faridkot.
Recent AQI data has also shown how pollution can change between night, early morning and daytime hours. In Delhi, pollution increased after sunset and in the early hours following Diwali, while levels fell later in the morning.
