How Severe Winter Weather Can Impact People with COPD and Asthma

January 23, 2026

Severe winter weather and extreme cold temperatures are affecting much of the Midwest including Illinois this weekend. For people living with COPD or asthma, cold weather can present additional challenges, as exposure to cold and dry air may worsen respiratory symptoms.

Extreme temperatures are a known trigger for asthma symptoms, and cold air can irritate sensitive airways. During winter storms, it is especially important for people with respiratory conditions to be mindful of how weather conditions may affect their breathing.

Cold air can narrow airways and make breathing feel more difficult, particularly during physical activity. Breathing through the mouth instead of the nose can worsen symptoms, as cold air does not have the chance to warm and humidify before reaching the lungs. This may increase the risk of coughing, shortness of breath, or asthma attacks.

Tips for Managing COPD and Asthma During Cold Weather

Taking simple precautions during extreme winter weather can help reduce symptom flare ups:

• Cover your mouth and nose with a scarf or face mask when outdoors to help warm and humidify the air you breathe
• Limit time outside during extreme cold and choose indoor activities when possible
• Keep rescue inhalers or prescribed medications accessible at all times
• Talk with your healthcare provider about managing symptoms during cold weather

Winter storms and cold temperatures can be stressful for people with COPD and asthma, but taking preventative steps can help protect lung health. Staying informed, limiting cold air exposure, and following your treatment plan can help you manage symptoms and get through the winter safely.
