In the summer, many people report reduced symptoms and fewer flare-ups, but for some, their condition gets worse. Heat and humidity acting as triggers could be the cause of this. Furthermore, some people's symptoms may worsen in the summer due to the higher concentration of pollen and other springtime allergens. Additionally, heat raises air pollution levels, which exacerbates asthma.
High temperatures and stagnant air can lead to an increase in ozone and air pollution to dangerous levels, resulting in poor air quality. Prolonged exposure can cause respiratory issues, particularly for people with asthma. Ozone is a primary component of smog.
