Climate change intensifies allergy conditions through increased humidity, heat, and flooding that promote mold growth in previously uncommon areas. After climate-driven disasters like hurricanes, mold allergies flare up particularly in older buildings or poorly ventilated homes, creating respiratory challenges for vulnerable populations.

Allergies extend beyond seasonal annoyances, disrupting sleep, increasing sinus infection risks, and causing missed work and school. A 2024 Texas study found allergies contribute to emergency department visits for asthma during high pollen periods. Wildfire smoke compounds these issues, forcing some patients indoors out of fear.

Drought prolongs pollen presence in the air as rain normally washes it away. For medical experts, the connection between allergies and climate hazards illustrates a modifiable risk factor requiring urgent action. The compounding effects of heat waves, pollution, and pollen create a perfect storm for respiratory distress.
