Asthma in the Summer: Does it Get Better or Worse?

As summer rolls in with its warm weather and long days, many individuals with asthma experience changes in their symptoms. For some, the season brings relief, while others find their asthma worsening. Knowing the factors that may influence asthma symptoms in the summer can help shed some light on whether or not asthma may improve or worsen in the summer season. 

Why Asthma Symptoms May Improve in the Summer 

Fewer colds: Viruses that cause upper respiratory infections are a common cause of an asthma exacerbation. Luckily, during the summer, there are not as many upper respiratory viruses circulating in North America.

Temperature: For some, cold air can be an asthma trigger so warm summer temps may decrease asthma flare-ups in this case. 

Reduced Indoor Allergens: With windows open and more time spent outside, exposure to indoor allergens such as dust mites, pet dander, and mold may decrease. This reduction in allergens can lead to fewer asthma symptoms for some individuals.

Why Asthma Symptoms May Worsen in the Summer

Pollen and Outdoor Allergens: Summer is a peak time for pollen. Pollen counts are often highest in the morning and on windy days, making these times particularly challenging for those with allergic asthma.

Air Pollution: Ozone and other pollutants are often higher in summer, especially in urban areas. Poor air quality can irritate the airways and trigger asthma flares.

Smoke: Whether it is from wildfires or campfires, smoke is a common asthma trigger for many people.

Weather: Rapid changes in weather and thunderstorms, which are common summer time occurrences in certain regions, can exacerbate asthma symptoms.

Physical Activity: People are often more physically active in the summer and some people's asthma is triggered by exercise. 

Travel: Being in a new environment means being potentially exposed to new or different asthma triggers (eg. different pollen counts in different regions, changes in air quality based on location, triggers such as mold or dust that are encountered while travelling).

Awareness and preparation are key to minimizing asthma triggers and ensuring a safe, fun-filled summer.

Here are some quick tips for managing asthma in the summer:

• monitor air quality
• monitor pollen counts
• keep an eye on weather forecasts
• travel prepared (packing all daily and rescue medications, travel insurance, and checking out what the weather/air quality/pollen counts at your destination are like)
• keep an up to date Asthma Action Plan
