Bengaluru is witnessing a surge in flu-like symptoms and respiratory infections, leaving many residents grappling with seasonal health challenges. The cool weather has led to an increase in illnesses such as seasonal flu, viral bronchitis, asthma, and respiratory allergies. Health experts attribute this seasonal spike to a combination of factors, including colder temperatures, reduced outdoor ventilation, and exposure to allergens.

The winter season brings a host of changes that create the perfect environment for respiratory ailments to thrive. Cooler temperatures often lead to increased indoor activities, where people are more likely to be exposed to airborne irritants. Dust, mould, and pollutants from common household activities such as cooking, burning incense, or lighting candles can exacerbate respiratory symptoms.

Additionally, the cold air itself can irritate the respiratory tract, triggering conditions such as asthma or bronchitis in sensitive individuals. The limited ventilation in closed spaces also allows viruses, bacteria, and allergens to accumulate, increasing the likelihood of infections.

- Dust and Mould:

Dust particles and mould spores thrive in damp, poorly ventilated areas. Bengaluru’s humid winters can make homes breeding grounds for mould, which can worsen respiratory allergies or asthma.

- Indoor Pollutants:

Pollutants from activities like cooking, burning incense, or using certain types of heating systems contribute to poor indoor air quality. Prolonged exposure to such pollutants can cause coughing, wheezing, and other flu-like symptoms.

- Viruses:

Seasonal flu viruses spread more rapidly in cooler weather, especially in closed spaces where people are in close proximity.

- Allergens:

Winter allergies, including pollen from certain plants, can trigger respiratory allergies, leaving individuals with runny noses, sneezing, or respiratory discomfort.

Tips To Stay Safe This Winter

While respiratory illnesses can seem inevitable during winter, taking a few precautions can significantly reduce your risk of falling ill.

- Ensure Proper Ventilation:

Good indoor air quality is crucial for respiratory health. Make it a habit to open windows during the warmer parts of the day to allow fresh air to circulate. Use exhaust fans in the kitchen and bathrooms to reduce humidity and eliminate odours and pollutants.

- Clean and Maintain Air Filters:

Air conditioning and heating systems can harbour dust and allergens. Regularly cleaning and replacing filters can improve the air quality inside your home.

- Opt for Low-Emission Alternatives:

Instead of traditional cooking and heating methods that release smoke or pollutants, choose low-emission appliances. Electric heaters and induction stoves, for example, are safer and healthier options for indoor use.

- Strengthen Your Immunity:

Build a strong immune system by maintaining a balanced diet rich in fruits, vegetables, and whole grains. Incorporate foods high in Vitamin C and antioxidants to support your body’s defence mechanisms.

- Practice Good Hygiene:

Wash your hands regularly with soap and water, especially after being outdoors. Avoid touching your face, as respiratory viruses often spread through contact with contaminated surfaces.

- Stay Active Indoors:

Physical activity is essential for lung health. If stepping outdoors isn’t feasible, consider indoor exercises like yoga or stretching to keep your body active and boost circulation.

- Use Masks if Necessary:

Masks can help filter out allergens and pollutants, especially during activities like cleaning or stepping out into areas with poor air quality.

- Stay Warm and Hydrated:

Dress warmly to prevent cold air from irritating your respiratory tract. Drinking warm fluids like herbal teas or soups can soothe your throat and help maintain hydration.
