Delhi is reeling under severe air pollution since Diwali. The quality improved a bit in November but yet again, the condition has detriorated.
Locals complaint of breathlessness and fatigue and have urged the government to take requisite measures to combat the menace.
"I feel sad that despite Delhi being the capital, there is so much pollution here. The government must do something about this. Too much smoke is around," a Delhi resident earlier told news agency ANI.
"It has been so many years that the problem of air pollution still persists in the national capital. All we can do is to keep ourselves fit," said another.
SAFAR has advised people residing in the national capital to reduce prolonged or heavy exertion.
"Take more breaks and do less intense activities. Asthmatics, keep medicine ready if symptoms of coughing or shortness of breath occur. Heart patients, see a doctor if you get palpitations, shortness of breath, or unusual fatigue," it said in an advisory.
