As winter sets in across northern India, particularly in Delhi, falling temperatures coincide with rising air pollution levels. This combination creates a hazardous environment for the respiratory system. Dr. Sushil Kumar Upadhyay, a New Delhi-based pulmonologist, describes this as "cold-pollution respiratory stress," a state in which chilled air and airborne contaminants together provoke coughing, chest tightness and breathing difficulty.

Dr. Upadhyay notes that cold air causes the bronchial tubes to constrict, while pollutants carry fine particles that penetrate the lungs and trigger inflammation. When both factors act together, the respiratory system must work harder, increasing the likelihood of symptomatic flare-ups.

In winter, stagnant air traps emissions from vehicles, industrial activity, waste burning and dust close to ground level. Smog thickens and people inhale harmful particulate matter throughout the day, which explains why many Delhi residents experience worse coughs, heavier breathing and more frequent chest discomfort in the colder months.

These effects are not confined to older adults. Children, adolescents and otherwise healthy people may also develop symptoms from repeated exposure. Reduced oxygen intake can produce fatigue, lightheadedness and, if unchecked over time, contribute to lasting lung damage.

Dr. Upadhyay cites World Health Organization findings showing that air pollution contributes to about 6.7 million premature deaths globally each year, many from cardiovascular and respiratory conditions linked to polluted air.

He recommends several practical measures to reduce risk during winter:

Wear certified masks such as N95 or KN95 when venturing outdoors.

Postpone early-morning outdoor exercise on days with heavy smog.

Keep windows and doors closed when pollution levels spike.

Drink warm fluids to soothe the throat and support breathing comfort.

Use indoor air purifiers where feasible to lower indoor pollutant levels.

See a physician if cough or breathlessness persists beyond a few days.

Patients with asthma or chronic lung disease should continue prescribed medications and consult their doctor before making any changes.

Dr. Upadhyay’s central message is clear: Delhi’s winter is not only colder but also a period of elevated air-related risk. Early attention and straightforward daily precautions can help protect respiratory health, because once substantial lung damage occurs it is difficult to reverse.
