Are long flights Bad for Your Health?

The cramped conditions and long periods of being less active on a flight can cause pain, stiffness or swelling of your legs. Being less active can lead to slow blood flow in your veins which increases your risk of developing a blood clot, known as deep vein thrombosis (DVT). DVTs most commonly form in the legs.
