How climate change makes your allergies worse

Climate change is making allergies worse by lengthening pollen seasons and raising pollen levels.

Flooding, humidity, and poorly ventilated spaces can boost mold growth and mold-related symptoms.

Heat waves, air pollution, and wildfire smoke add more irritation and can worsen asthma.

The result is longer-lasting, more severe allergy seasons that disrupt sleep, work, and health.
