Increased humidity, heat, and flooding are creating conditions for mold to grow in new areas, while drought can cause pollen to linger for weeks. These climate-driven changes are exacerbating seasonal allergies, which can affect sleep, increase infection risk, and lead to missed work or school. A recent study found allergies account for a significant portion of asthma-related emergency visits during high pollen periods.
Facts First
- Increased humidity, heat, and flooding are expanding mold growth into previously rare locations.
- Seasonal allergies can cause itchy eyes, runny noses, and symptoms similar to a cold.
- Pollen can affect sleep, increase sinus infection risk, and lead to missed school and work.
- A 2024 Texas study found allergies account for a significant portion of emergency department visits for asthma attacks during high pollen.
- People with allergies are sensitive to respiratory triggers like heat waves, air pollution, and wildfire smoke.
What Happened
Climate factors like increased humidity, heat, and flooding are creating conditions for mold to grow in locations where it was previously rare. Mold allergies can flare up following climate-driven disasters like hurricanes or for individuals in older buildings, basement units, or homes lacking proper ventilation. Seasonal allergies can also be worsened by drought, which causes fine pollen powder to blow around for weeks instead of being washed away by rain.
Why this Matters to You
Your seasonal allergies may become more severe or last longer due to changing climate patterns. If you live in an older building, basement unit, or a home with poor ventilation, you may be more susceptible to mold allergies. Allergy symptoms can disrupt your sleep, increase your risk of sinus infections, and potentially lead to missed days at work or school. For those with asthma, high pollen days could significantly increase your risk of needing emergency care.
What's Next
People with allergies are likely to face compounding respiratory stressors, such as heat waves combined with increased air pollution or wildfire smoke. Medical professionals may need to prepare for more patients experiencing the effects of multiple triggers on days with heavy smoke or high pollen counts. Public health messaging could increasingly focus on the intersection of climate conditions and respiratory health.
