Winter in Canada can be especially challenging for people living with asthma. As temperatures drop, cold, dry air can irritate the airways and trigger symptoms such as coughing, wheezing shortness of breath and even lead to hospitalisation.  

Respiratory infections like the flu, RSV, and pneumonia are also more common in winter and are major asthma triggers. At the same time, people spend more time indoors where dust mites, pet dander, mould, and dry air from heating systems can further aggravate symptoms. Even outdoor activities such as skating or skiing can cause exercise-induced asthma if you’re not properly prepared. 

The good news? With the right precautions, you can stay in control of your asthma all winter long.  

Winter Wellness Tips for People with Asthma

Check in with Your Healthcare Professional: 

Winter can be especially challenging for people with asthma. Regular follow-ups with your healthcare team help ensure your treatment stays on track. You can also reach out to Asthma Canada’s HelpLine for additional information and support. 

Follow Your Asthma Action Plan: 

Make sure your Asthma Action Plan is up to date and review it with your healthcare provider. Having a clear plan, and following it closely, helps you stay prepared if your symptoms worsen. 

Take Your Controller Medication: 

Don’t skip your daily controller medication, even if you feel well. These medicines work in the background to keep your airways less inflamed and more stable, which is especially important during the colder months. Using a spacer with your asthma medication can lead to better medication delivery. 

Be Prepared For An Asthma Emergency:  

Always keep your reliever inhaler with you in case of sudden symptoms and know your Asthma Action Plan steps for what to do during and after an asthma emergency.

Stay Up to Date on Vaccinations: 

Respiratory infections can trigger severe asthma symptoms. Protect yourself by staying current on recommended vaccines, including flu, pneumococcal, RSV, shingles, and COVID-19.  

Know Your Winter Triggers & How to Combat Them: 

• • Cold air: When out and about, cover your nose and mouth with a scarf to warm the air before you breathe it in.
  • Indoor triggers: Reduce exposure by cleaning regularly for dust, mould and pet dander. Avoid smoke from fireplaces and choose unscented products when possible
  • Stress: Winter can be isolating and stressful. Prioritize your mental health with relaxation techniques, regular exercise, and staying connected with friends or support networks.
