Winter can be a difficult season for people with asthma and allergies. As temperatures drop and air quality worsens in most cities, breathing problems often become more common. Knowing what triggers these issues can help you stay prepared and protect your health.
Why Do Asthma & Allergies Get Worse in Winter?
Cold air is one of the biggest triggers for asthma. When you breathe in cold, dry air, it can irritate the airways and cause coughing, wheezing or shortness of breath. Many people also spend more time indoors during winter, which increases exposure to indoor allergens. Air pollution is another major problem in most metro cities. During winter, pollution levels rise due to low wind movement and increased use of heaters and vehicles. Polluted air can inflame the lungs and worsen asthma symptoms.
Common Winter Triggers
- Cold and Dry Air
Sudden exposure to cold air can tighten airways and trigger asthma attacks - Dust and Dust Mites
Closed windows and carpets allow dust to stay indoors - Smoke from Heaters and Bonfires
Wood, coal and firecrackers release harmful particles into the air - Mould and Dampness
Moist areas at home encourage mould growth, which can further trigger allergies - Respiratory Infections
Cold, flu and viral infections are more common in winter and can worsen asthma
How to Protect Yourself
- Cover your nose and mouth with a scarf when stepping out in cold weather.
- Keep indoor spaces clean by regular dusting and avoiding carpets as much as possible.
- Avoid smoke exposure, including indoor heaters, bonfires and passive smoking.
- Monitor air quality and limit outdoor activity when pollution levels are high.
- Always keep your inhaler handy.
