Delhi’s air quality often worsens in the cooler months, and preparing early can protect your health. Start by checking the daily AQI and planning outdoor activity for cleaner hours. Keep well-fitted N95 or similar masks at home, and use an air purifier or keep indoor air clean if possible. Review your medicines and inhalers with your doctor, especially if you have asthma, COPD, heart disease or diabetes, and get recommended vaccines such as the annual flu shot. Build your immunity with a balanced diet, enough water, good sleep and regular exercise indoors on high-pollution days. Children, older adults, pregnant women and people with existing conditions are most at risk. Seek medical help for persistent cough, wheezing, breathlessness, chest discomfort or eye and throat irritation that does not ease.
