Weather Changes and Asthma

Often changes of weather (rather than a particular temperature) can trigger asthma. The arrival of spring and autumn seem to be trigger times. Asthma can be troublesome in winter but more usually because of colds and flu rather than the season itself.

What to do:

Take your usual dose of reliever inhaler before going out on cold, dry days.
If it is cold and windy, wear a scarf over your face to help to warm up the air before you breathe in.
Try to avoid going out in the middle of the day on hot, smoggy days.

Winter Survival Guide

Surviving the winter with asthma


1.  Take Medication as Prescribed

This is vital all year round! It will help you control your asthma better and hopefully prevent an asthma attack. To check your technique, watch our inhaler techinique videos.

2.  ALWAYS Carry Your Blue Inhaler

Having this inhaler with you means in the case of an asthma emergency, you have a tool which will hopefully help the symptoms subside. However, if you are taking it more than twice a week it could be a sign that your asthma isn’t controlled. If this is the case, visit your GP or healthcare professional.

3.  Have an Up-to-Date Asthma Action Plan

The Asthma Action Plan helps you in the management of your asthma and may help to identify if your symptoms mean you need a check up. You can download an Action Plan and complete it with the help of your GP or our free Asthma Adviceline (1800 44 54 64).

4.  Use Your Nose

Breathing through your nose is ideal during the winter as it warms the air up before bringing it to the lungs. So limit breathing through your mouth to reduce the exacerbation of your asthma.

5.  Make Your Home Asthma Friendly

When winter arrives, we spend an extraordinary amount of time indoors. With the cold, many fires and candles are lit. A lot of homes bring animals indoors due to the weather outside. All of those actions may trigger your asthma. To find out more on what you can do to make your home more asthma friendly, visit

6.  Flu Jab: Better Late Than Never

Protect yourself against the flu this season. Visit your local pharmacy or GP to get the vaccine, if you haven’t already.
