Winter in Bengaluru brings with it a range of respiratory illnesses, including seasonal flu, viral bronchitis, asthma exacerbations and respiratory allergies. The cool temperatures, increased indoor activities and exposure to allergens contribute to these ailments. By adopting preventive measures and making conscious lifestyle changes, you can stay healthier this winter.

Dr Pavan Yadav, Lead Consultant - Interventional Pulmonology & Lung Transplantation at Aster RV Hospital, highlights, “In winter, air pollutants are higher due to temperature inversion, which traps pollutants near the ground. This exacerbates asthma and chronic lung conditions like COPD. Symptoms, such as coughing, wheezing and throat irritation, may develop due to fine particulate matter (PM2.5).” To protect yourself from pollution and its impact, Dr Pavan Yadav suggests this: “To protect yourself from pollution, avoid going out during peak pollution hours, which are typically early morning and late evening and wear N95 masks when stepping outside.” He added, “It is also beneficial to keep air purifiers at home to improve indoor air quality and you might consider adding indoor plants such as peace lilies and areca palms, which can help with natural air purification.” Additionally, monitoring outdoor air quality through credible sources can assist you in planning your activities more effectively. Indoor air quality tends to worsen in winter due to reduced ventilation and heating appliances.

Common culprits include dust, mold and pollutants from cooking or burning incense. Ensuring good indoor air quality involves ensuring adequate ventilation. It is important to open windows during the warmer parts of the day, use exhaust fans in the kitchen and bathrooms, regularly clean air conditioning and heating filters and opt for low-emission cooking and heating alternatives.

Dr Yadav also underscores the impact of climate change on respiratory health in Bengaluru. “Rising temperatures and sporadic rains have led to an increase in pollen counts and worsened conditions for allergy and asthma patients. Seasonal unpredictability raises infection rates and susceptibility to respiratory illnesses,” he explains.

Vaccination is a critical preventive measure. Flu shots reduce the intensity of influenza infections and associated complications, especially in children, the elderly and individuals with chronic conditions. To enhance winter wellness, it is important to stay hydrated to maintain the health of mucosal regions and consume a balanced diet rich in vitamins.
