Dry indoor air is often overlooked, yet it can be just as problematic as high humidity, impacting both comfort and health. Recent studies even suggest that prolonged exposure to excessively dry air can elevate stress levels.
Moreover, dry air can exacerbate existing indoor air quality issues. Studies indicate that it amplifies the adverse effects of high particulate matter and VOC levels.
Monitoring indoor humidity is crucial, especially since many buildings lack adequate humidity control. While opinions vary on optimal humidity levels, experts generally recommend maintaining humidity between 35 and 60 percent.
Health Effects of Dry Air
Dry indoor air primarily affects the respiratory system. Dryness can lead to irritation and infection in nasal, sinus, and bronchial passages, exacerbating conditions like asthma, bronchitis, and sinusitis. It also heightens the risk of respiratory infections like colds, flu, and Covid-19.
Dehydration is another concern. Dry air can dehydrate the eyes, causing irritation, dryness, and susceptibility to eye conditions. It also dries throat tissues, leading to swallowing difficulties, throat pain, and hoarseness. Skin can also suffer from dryness, resulting in discomfort, rashes, and infections.
Impact on Stress and Sleep Quality
Dry air isn’t just physically discomforting; it can also impact mental well-being. Studies show a correlation between dry air and increased stress levels, as well as reduced sleep quality. Workers in environments with low humidity experienced higher stress and poorer sleep compared to those in properly humidified spaces.
Combatting Dry Air
During the cold seasons, central humidification systems can help replenish lost moisture caused by heating systems. These systems regulate humidity levels for optimal comfort and health.
During the hot seasons, air conditioners should maintain moderate humidity levels. If your AC is oversized or malfunctioning, it may dry out the air excessively. Regular HVAC maintenance and adjustments can ensure proper humidity control and improve overall comfort and health.
