As the pollution level in Delhi peaked to a three-year high on Sunday, Union Minister for Health Harsh Vardhan took to Twitter to impart tips on how to stay away from pollution-related diseases.

Harsh Vardhan said that eating carrots would help a body get required nutrients to avoid polluted-related harms to health.

"Eating carrots helps the body get Vitamin A, potassium, & antioxidants which protect against night blindness common in India. Carrots also help against other pollution-related harm to health," Harsh Vardhan tweeted.

The Central government on Sunday reviewed the situation with the governments of Delhi, Haryana and Punjab and announced that Cabinet Secretary Rajiv Gauba would monitor it on a daily basis.

After Delhi, all schools up to Class 12 were also closed in the National Capital Region (NCR) till November 5 following a spike in the pollution level in the region.

The heavy smog caused a major disruption at Delhi airport as 37 flights were diverted and more than 250 departures and 300 arrivals delayed due to poor visibility, officials said.

According to the Central Pollution Control Board (CPCB), the national capital's 24-hour average air quality index (AQI) stood at 494 at 4 pm on Sunday, the highest since November 6, 2016, when it was 497.

Twenty-one of the 37 air quality monitoring stations recorded AQI between 490 and 500 and air quality sensors at Aya Nagar, Ashok Vihar, Anand Vihar and Aurobindo Marg peaked out at 7 pm.
