Change in weather (cold air and extreme weather)
Depending on the season, there are certain events or conditions that can trigger your asthma symptoms. This can include thunderstorms, extreme temperatures, poor air quality and changes in weather. We can’t always avoid these events, but we can try to reduce their impact.
Exposure to cold air can lead to asthma flare-ups. Cold air can cause dryness in your airways and cause the muscles to tighten. However, for some people it might be hot dry weather or an increase in humidity that can trigger their asthma symptoms. Understanding how the weather triggers your asthma can help you to be prepare for changes in weather. For example, wearing a scarf in cold weather can help humidify, warm and filter the cold dry air you breathe.
