As international travel rebounds, millions are preparing to board planes for holidays and family visits. While commercial air travel is generally considered a safe mode of transportation, health experts caution that flying can present unique challenges for your body—especially your heart, lungs, and sinuses.
Dr. Leigh Speicher, president of the US Civil Aviation Medical Association, emphasizes, “Overall, it’s a very safe mode of transport.” However, Dr. Laurence Sperling, a professor in preventive cardiology at Emory University School of Medicine, notes that flying can trigger a range of health issues, from mild stress to complex physiological changes affecting the heart, blood vessels, and the brain-heart axis.
Potential Health Risks in the Air
-
Dehydration: The low humidity inside aircraft cabins can lead to dehydration. Passengers are encouraged to drink water regularly and avoid excessive caffeine or alcohol, which can exacerbate fluid loss.
-
Thrombosis: Prolonged immobility on long-haul flights increases the risk of blood clots, particularly in the legs. Experts recommend moving around the cabin periodically and performing simple leg exercises in your seat.
-
Heart and Lung Strain: Individuals with pre-existing heart or lung conditions may experience exacerbated symptoms due to reduced oxygen levels in the cabin. Consulting a healthcare provider before flying is advised for those with known cardiovascular or respiratory issues.
-
Sinus and Ear Discomfort: Changes in cabin pressure can cause discomfort in the sinuses and ears. Chewing gum, swallowing, or using specialized earplugs can help equalize pressure and relieve symptoms.
Expert Advice for a Healthy Flight
-
Stay hydrated by drinking water frequently.
-
Move and stretch regularly during the flight.
-
Avoid alcohol and caffeine before and during travel.
-
Consult your doctor if you have chronic health conditions.
-
Use saline nasal sprays or decongestants if you are prone to sinus issues.
“Issues range from simple stress to complex physiologic changes that can affect the heart, blood vessels and brain-heart axis,” says Dr. Sperling.
