The Delhi government issued a health advisory on Sunday in view of the severe air pollution in the city and asked people to avoid outdoor activities as much as possible, especially during the morning and late evening hours.
In a statement, Delhi Health Minister Satyendar Jain said the air pollution had reached the severe level and asked people to follow the dos and don'ts as mentioned in the advisory.
The advisory said the air pollution might cause respiratory problems in healthy people on prolonged exposure and pronounced respiratory or other serious illnesses for the vulnerable population even on short exposure.
"The general public is, therefore, advised to avoid outdoor physical activities, especially during morning and late evening hours," it stated.
The vulnerable population was advised to strictly avoid outdoor activities, remain indoors and keep activity levels low.
The vulnerable population comprises elderly people, children aged below five years, pregnant women and those with a poor nutritional status.
Traffic police personnel, rickshaw-pullers and roadside vendors were advised to take extra precautions.
The dos and don'ts asked people to remain indoors and reschedule their outdoor activities, consult doctors in case of breathlessness, giddiness, cough, chest discomfort or pain and irritation in the eyes.
Using N95 masks, avoiding heavy traffic and polluted areas, keeping doors and windows closed in the morning and late evening were also advised by the government.
It also asked people to use public transport, avoid driving two-wheelers and other vehicles, and stop smoking.
Delhi, Ghaziabad, Gurgaon and Faridabad schools to remain closed till Tuesday
All government and private schools in Noida, Ghaziabad, Gurgaon and Faridabad will remain closed till Tuesday in the wake of spike in pollution levels, officials said.
Gautam Buddh Nagar and Ghaziabad administrations said the decision has been taken as the levels of particulate matter 2.5 and 10 have been excessive in the air since Diwali, resulting in a major dip in the overall air quality.
"Transport vehicles like buses and minibuses, which a lot of schools use to ferry children, are a major contributor of PM 2.5 and PM 10. The movement of such vehicles in the city now could aggravate the situation," District Magistrate B N Singh said in a written order.
"Hence, it is ordered that all schools up to Class 12 in Gautam Buddh Nagar will remain closed on November 4 and 5," he added.
