What is an asthma trigger related to air travel?

• A. Cabin pressure
• B. Dry air in the cabin
• C. Excess humidity
• D. Noise levels during the flight

Answer: (B)

Dry air in the cabin is a significant asthma trigger during air travel because the air inside an aircraft is typically much drier than at ground level. This low humidity can lead to dehydration of the respiratory membranes, making it harder for asthmatic individuals to breathe. The dry air can cause irritation of the airways and may trigger asthma symptoms such as coughing, wheezing, or shortness of breath. Therefore, individuals with asthma may need to take precautions, such as using a humidifier or carrying a saline nasal spray, to help manage symptoms during flights. Other factors, like cabin pressure and noise levels, while potentially impactful, do not pose as direct a threat to asthma control as dry air. Excess humidity is generally not a concern in airplane cabins, as the environment is engineered to minimize moisture for comfort and safety in flight.
