[i]...in the unexpected discovery, researchers have found that spending time in space can affect how blood flows through a major blood vessel in the upper body, causing it to halt or even flow backwards — a health risk that was unknown until now. In the study, [URL=https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2755307]published Wednesday (Nov. 13) in JAMA Network Open[/URL], a medical journal published by the American Medical Association, researchers examined 11 healthy astronauts who had stayed aboard the International Space Station for an average of six months. During routine ultrasound assessments, by the 50th day of their missions, seven crew members were found to have stagnant or reverse blood flow in their left internal jugular vein, a major blood vessel that runs down the side of the neck and is responsible for draining blood from the brain, face and neck. One astronaut was also found to have developed a clot in the internal jugular vein during spaceflight, and a partial clot was discovered in another crew member after returning to Earth, according to the study.[/i]
