In terms of maintaining cabin atmosphere, why is monitoring humidity important?

Monitoring humidity in maintaining cabin atmosphere is crucial for ensuring passenger comfort and health. Proper humidity levels contribute to a pleasant and comfortable environment for passengers by preventing the air from becoming too dry. Dry air can lead to discomfort such as dry skin, dry eyes, and respiratory issues, which can significantly affect the overall flying experience.

Moreover, maintaining appropriate humidity levels can help reduce the likelihood of the spread of airborne viruses and bacteria, contributing to a healthier environment onboard. This is particularly important in a closed environment like an aircraft cabin, where passengers are in close proximity to one another for extended periods.

While there are other factors related to cabin environment, such as lighting and temperature, addressing humidity directly supports both comfort and health, making it a primary concern in cabin atmosphere control systems.
