Asthma is a chronic lung disease that leads to narrowing of the lung’s airways when exposed to certain triggers. For many asthmatics, Iowa’s cold winter is one of those triggers. Breathing cold, dry air can cause cells in the airways to release products that inflame the bronchial airways, increase mucus production, and result in impaired breathing.

If you suffer from asthma, keep a record of your behavior. You may be able to identify specific triggers, such as an allergic reaction, exposure to strong odors, dusty or smoky conditions, or emotional situations.

If the cold weather is a definite trigger to asthma attacks, consult with your family doctor to see if your asthma treatment should be changed during the wintry weather. Take your asthma medication as directed and always carry your asthma rescue medication.

Joel N. Kline, MD, UI Asthma Center director, recommends the following to improve asthma control this winter:

• Wear a scarf or cold-air face mask that covers your nose and mouth to warm the air you breathe, reducing exposure to the cold, dry air
• Breathe in through your nose instead of your mouth when you’re outside to warm and humidify the air before it enters your lungs
• Use your bronchodilator 30 minutes before going outside to open constricted airways and prevent some attacks
• If you ordinarily exercise outdoors, consider moving indoors
• Avoid being around wood stoves or fireplaces because the particles given off can irritate airways and lead to cold-weather sensitivity
