“Road traffic may also be slower due to the fog, so we recommend allowing additional time while planning your journey to the airport. Our teams are closely monitoring the situation and will keep you updated. As conditions improve, we will continue departures with safety at the forefront,” it added.

IMD issues alert

The India Meteorological Department (IMD) has issued an orange alert for dense fog, advising people to exercise caution. According to the IMD, night-time temperatures dropped to 8.2°C.

Footage from Anand Vihar and Akshardham showed these areas shrouded in a heavy layer of toxic smog, with the AQI reaching 493, firmly in the 'Severe' category. Similar conditions were reported in Dwarka, where the AQI stood at 469, also classified as 'Severe'.

Are Delhi schools closed on Monday, 15 December?

Delhi Government's Directorate of Education on Saturday gave the following directions for schools in the national capital:

- Under the instructions issued, all schools have been asked to shift to hybrid classes for students up to Class IX and XI. Classes are to be conducted by combining both offline and online teaching wherever feasible, and schools are to continue with this arrangement until further notice.

'Avoid outdoor walking,' urges health expert

Health expert Shila Yadav warned that with the AQI ranging from 300 to 400 and occasionally exceeding 450, people should refrain from outdoor walks or exercise, especially in the morning, PTI reported.

She added that while staying active remains important, workouts should be moved indoors, as breathing polluted air allows fine particles like PM2.5 to travel deep into the lungs and pose serious health risks.

Yadav advised people to step out only when necessary, preferably later in the day when sunlight improves dispersion, and said wearing masks was essential for those who must go out for work.

She also cautioned against strenuous activities that involve heavy breathing and emphasised the importance of a healthy diet, adequate hydration, and the consumption of seasonal fruits to help the body flush out toxins.
