Dry indoor air is a significant concern in residential buildings, particularly in Nordic climates where heating systems often reduce indoor humidity levels. This study investigates the relationship between indoor environmental conditions – specifically, temperature and relative humidity – and symptoms of dry eyes, nasal, and throat irritation among residents of Danish apartment buildings. Using survey responses and indoor climate measurements from 75 participants in Copenhagen and Odense, the study found a weak inverse correlation between indoor humidity/temperature and irritation symptoms. However, variations in symptoms suggest other contributing factors, such as air pollutants and ventilation rates, require further investigation.”
