What effect can low cabin humidity have on passenger health?

Low cabin humidity can lead to a heightened risk of dehydration among passengers. When the moisture content in the air is low, as is often the case during flights due to pressurization and environmental factors, it can cause the body to lose water more quickly. This can result in symptoms such as dry mouth, dry skin, and increased thirst, all of which indicate dehydration. The lack of humidity in the cabin can also exacerbate the natural moisture loss that occurs during flight, leading to discomfort and potential health issues if not addressed. Therefore, recognizing the impact of low humidity on hydration is critical for maintaining passenger comfort and health during air travel.
