Low humidity has a significant impact on the comfort and health of indoor occupants, primarily because it can lead to dry skin and respiratory issues. When humidity levels are low, the moisture content in the air decreases, which can result in the evaporation of moisture from the skin and respiratory tract. This can cause skin to become dry and irritated, leading to discomfort. Additionally, low humidity can affect the mucous membranes in the respiratory system, leading to irritation and an increased likelihood of respiratory problems such as allergies or infections.

The discomfort from dry air can also lead to other health issues, such as nosebleeds or exacerbated asthma symptoms. Since the respiratory system relies on adequate humidity to function optimally, a drop in humidity levels can hinder its ability to trap and filter out allergens and pathogens effectively.

Recognizing the effects of low humidity helps in maintaining an environment that promotes health and well-being within indoor spaces, making it crucial for indoor air quality assessments and management.
