Health risks that affect frequent flyers and how to prevent them
Deep vein thrombosis (DVT) or economy class syndrome
It is not so much where you are, but what you do, that affects your body’s blood clotting system.
Sitting for long periods, rather than the plane cabin environment, can increase your chances of developing a blood clot in one of your thighs or calves. This condition, known as deep vein thrombosis (DVT), can result in muscle pain, swelling, tenderness and redness around the affected areas.
Deep vein thrombosis can become a serious health risk if the blood clot travels to your lungs. Once lodged in a lung, the blood clot can cause chest pains and make it hard for you to breathe. In extreme cases, this may lead to death within days or even hours.
How to prevent deep vein thrombosis
To prevent deep vein thrombosis, you must find ways to improve your blood circulation before and during the flight.
Wear comfortable socks: Before the flight, you may put on travel compression socks as they can assist with blood flow and prevent blood clotting. Alternatively, avoid wearing tight socks or stockings.
Move around: When the plane is in cruising mode, get out of your seat and walk up the aisle every hour or two. Take the opportunity to go to the bathroom, stretch your calves and wiggle your toes. Consider requesting for an aisle seat so you can move about more easily.
Drink water: Avoid alcoholic or caffeinated beverages that are dehydrating and drink plenty of water instead.
