As any good cardiologist would tell you, blood flow is key to your health.  They probably won’t tell you that gravity is key to blood flow.  But that’s probably because they don’t usually have to deal with patients that aren’t subject to gravity.  When people are no longer subject to gravity, such as astronauts resident on the ISS, that lack of gravity can become a problem, especially when dealing with sensitive soft tissues such as the eyes.  To solve that problem, a team of scientists and engineers have the University of Texas Southwestern have developed a special type of sleeping bag that might help astronauts with their blood flow issues caused by gravity, and potentially get their sight back.
