What does flying do to your body? Top cardiologists explain how to protect your heart on a flight

While generally safe, flying introduces physiological changes due to cabin air pressure and altitude. Cardiologists highlight that reduced air pressure inside an aircraft can lead to lower oxygen levels in the blood, potentially impacting heart function, especially for individuals with pre-existing conditions. Dehydration, often exacerbated by dry cabin air, can also increase heart rate and blood clot risk.

To mitigate these risks, cardiologists recommend staying hydrated by drinking plenty of water throughout the flight and avoiding excessive alcohol or caffeine. Moving around the cabin periodically can help improve circulation and prevent blood clots. Passengers with known heart conditions should consult their doctor before flying and consider wearing compression socks to promote blood flow.

Furthermore, the stress associated with air travel can also affect heart health. Passengers are advised to practice relaxation techniques such as deep breathing or meditation to manage anxiety. By taking these precautions, passengers can minimize the potential impact of flying on their cardiovascular system and ensure a safer and more comfortable journey. The article emphasizes proactive measures to safeguard heart health during air travel.
