Apart from this, it also affects your heart. In an Instagram post shared on November 12, Dr. Dmitry Yaranov, MD, a cardiologist who specializes in heart failure, advanced heart failure, and heart transplantation, explained in detail the effects of flying. Let us know what the cardiologist shared.
This is what flying does to your heart
“Most people think that flying is just sitting in a chair in the sky. But your body is doing real work up there,” Dr. Yaranov explained, sharing the effects of flying on your cardiovascular health. Here’s what happens in our hearts when we’re up in the air:
Cardiology Edition: What happens during flight, according to cardiologist Dr. Yaranov
• When cabin pressure drops, your oxygen levels drop.
• This causes your heart to work harder to provide the same oxygen it was previously providing to your body.
• Additionally, cabin air is drier than desert air, which is why your body loses water just by breathing.
• Your blood volume also decreases when you fly, which means your blood becomes slightly thicker.
• Additionally, sitting for long periods of time in flights slows down blood circulation, making our legs heavy and swollen.
• Eventually, the lining of your airways also dries out, weakening the immune system barrier.
The cardiologist also said that the ‘jet lag’ you feel after a flight is not just due to time zones. Rather, it is your physiology.
How to protect your heart?
The cardiologist also explained what he does to protect his heart health on every flight. Here’s what he recommends:
• Hydrate before boarding (start in the front, not the back).
• Release salt and alcohol into the air (both thicken the blood).
• Stand up and stretch every hour to keep circulation going.
• Use saline nasal spray before flying to protect your immune system.
• Walk after landing to reset blood flow and oxygen delivery.
The cardiologist finally advised, “Small habits. Make a huge difference when you land. Your heart travels with you. Treat it like it matters.”
