What does humidity measure?

Humidity specifically measures the amount of water vapor present in the air. It is an important concept in respiratory care and atmospheric sciences because water vapor can influence various physiological processes and the comfort level in a given environment. High humidity levels can make the air feel warmer and more oppressive, while low humidity can lead to dryness that may affect the respiratory tract and overall comfort.

Understanding humidity is critical in respiratory care as it relates to administering therapies such as oxygen and humidified air, ensuring that patients receive adequate moisture to prevent airway irritation or other complications. This knowledge helps caregivers create environments that support effective respiratory function and comfort for patients.
