With an estimated 4.7 billion people expected to travel by plane this year, it’s crucial to be aware of the potential impact on our bodies. One area of concern is the effect on our lungs due to the reduced air pressure in the cabin environment.
The air pressure inside planes is approximately 75% of what we are accustomed to at sea level, leading to lower oxygen levels. While healthy passengers generally adapt without severe complications, some individuals may experience symptoms such as discomfort, fatigue, increased heart rate, or mild shortness of breath.
To minimize these effects, Dr. Lawrence Cunningham, a medical expert and retired GP, recommends taking proactive steps before and during air travel. Staying hydrated by drinking plenty of water is essential, as cabin air tends to be dry and can exacerbate feelings of breathlessness.
Light stretching and movement during the flight promote better circulation and maintain optimal lung function. Using a saline nasal spray can keep nasal passages moist and defend against airborne pathogens. Dr. Cunningham also emphasizes the benefits of deep breathing exercises, which improve lung capacity and help reduce anxiety that can indirectly affect breathing efficiency.
Individuals with respiratory conditions like chronic obstructive pulmonary disease (COPD) or asthma may face challenges during air travel. Worsening symptoms, such as coughing and difficulty breathing, can occur due to the low humidity in the cabin. Consulting a doctor before flying is crucial to discuss precautions and consider the potential need for supplemental oxygen during the flight.
Dr. Cunningham’s advice aligns with other travel tips shared by experts. Avoiding caffeine and alcohol on flights can prevent further dehydration and potential sleep disturbances. Instead, staying hydrated, listening to calming podcasts or meditation apps, and practicing deep breathing can promote restful sleep and minimize jet lag.
