DVT (deep vein thrombosis) is a condition that is caused by blood clot partially or fully blocking a blood vessel. Thousands of people are affected by DVT each year. When blood flow is slowed (this can be caused by something like sitting still for a long period of time), clots are more likely to form in the deep veins in your legs. Dry air and dehydration can encourage DVT as well. The symptoms of DVT are pain or swelling in part of your leg. There is a risk of fatality because the clot could make its way to your brain or lungs.
DVT has a hypothetical link to flying because people are forced to sit for such long periods of time. It has even been nicknamed “economy class syndrome.”
One way to reduce the risk of DVT is through compression. Flight socks have been shown to reduce a person’s risk of Deep Vein Thrombosis by 90%. A side benefit of flight socks is that they also improve edema (unusual water retention).
Researchers believe that flight socks work because they apply pressure to a person’s calf, which in turn applies pressure to veins that are deep inside the leg. That causes blood to pump more rapidly and helps prevent clots.
Compression bandages can have the same affect. They are best applied around your ankles and encourage blood flow in the same way the flight socks do.
Flight socks and compression bandages could be a wonderful niche product for eBay, especially if you sell travel or health care items.
