"Health Risk: Triggers Health alert. Everyone may experience more or serious health effects. Significant increase in respiratory effects in general population," SAFAR said. It further advised people to stop outdoor activity at early morning and after sunset times. "Avoid prolonged or heavy exertion. Go for a short walk instead of a jog and take more breaks," it said. It urged people to stop any activity level if someone experiences any unusual coughing, chest discomfort, wheezing, breathing difficulty, or fatigue. "If the room has windows, close them. If the air conditioner provides a fresh air intake option, keep that closed. Avoid burning of wood, candles or incense. Keep the room clean - do not vacuum. Do wet mopping to reduce dust," it added. The air quality measuring agency urged people to wear masks known as N-95 or P-100 respirators while going out.
