Low humidity levels, specifically those dropping below 30%, are identified as significant risks to respiratory and skin health. Dry air can lead to the drying of mucous membranes in the nose and throat, which increases vulnerability to allergies, asthma, rhinitis, and infections. 

In 2024, dry periods were associated with a 27% increase in respiratory disease diagnoses compared to the prior year. Physical symptoms linked to low humidity include headaches, fatigue, dehydration, and skin irritation such as itching and cracking.
