Delhi’s AQI remains in “very poor” category at 374. Experts share tips on reducing smog exposure, protecting lungs, and staying safe this winter.

Delhi Air Pollution: According to CPCB data, Delhi’s Air Quality Index (AQI) remained in the “very poor” category at 374, particularly in RK Puram. Even though there was a slight improvement, the quality of the air declined once more, with multiple monitoring sites reporting severe levels that above 400. Furthermore, a thick layer of poisonous smog continued to cover a sizable portion of Delhi, severely impairing visibility and making life uncomfortable for locals. According to recent findings, fine particles (PM2.5) enter the bloodstream and lungs deeply when the AQI falls into the “very poor” category. This causes persistent inflammation and adverse consequences on the heart, brain, and lungs. However, you may protect yourself from the harmful smog by making small lifestyle adjustments and using smog prevention advice.

Sensitive populations are impacted by this poisonous pollution, including children, the elderly, and people with asthma who are at risk for bronchitis, asthma episodes, and even permanent harm. According to a 2025 study, the number of deaths attributable to pollution can exceed the baseline by about 40 deaths each day. However, Delhi AQI protection tips need greater attention because of the changes in winter lifestyle. Look at this:

Simple Strategies to Lower Delhi’s Smog Exposure

Enhance the Quality of Indoor Air

When the AQI is high, especially in the morning and late at night, keep windows closed. Depending on the size of the room, use a HEPA-filter air purifier in both your bedroom and main living area. It can considerably reduce indoor particulate concentrations, but it won’t completely remove the risk.

By refraining from burning charcoal or incense indoors, you can also lessen indoor pollution sources.

Time Spent Outside

When the AQI improves, such as after rain or during the day when dispersion is better, schedule any outdoor activities. If at all possible, remain inside on days when the AQI is higher than 300. Wear a properly fitting N95 mask or one similar to it if you go outside.

Humidity and Ventilation Indoors

After cooking or if the air inside becomes stagnant, use exhaust fans or air exchanges. The overall exposure load on your lungs is decreased by cleaner indoor air.

Make preventive care and medical check-ups a priority.

You should discuss your smog season plan with your doctor if you have heart illness, asthma, COPD, or are elderly.

When the AQI is exceptionally high, even healthy individuals may be at higher risk. It’s important to pay attention to even minor symptoms like coughing or dyspnea.

Given that Delhi’s AQI is currently above 370, take control and adopt sensible, healthful wintertime practices to lessen the negative effects of smog on the lungs and body as a whole. After all, your best course of action when the air refuses to cooperate is to give your body every opportunity to withstand the harm.
