An international group of scientists has discovered the mortal danger of long-term space flight on the health of astronauts. It turned out that the microgravity environment causes a disturbance in the internal jugular vein. This can become a significant problem for a manned mission to Mars. This publication reports Science Alert.

Experts surveyed 11 astronauts on the ISS. It turned out that over 50 days of stay in weightlessness in the jugular there is stagnation and reverse flow of blood. One of the crew members were identified thrombosis or occlusion of the vein that was first observed during space flight. Until the end of the mission, the astronaut had to be treated with anticoagulants.

As the authors of the scientific article, microgravity contributes to chronic the outflow of blood and tissue fluid to the head with unknown consequences for the circulation of the brain. Enhanced swelling of the face, increasing the volume of blood circulating in the heart and a reduced plasma volume.

No one knows what might be the consequences for the health of astronauts, researchers fear that weightlessness can lead to life-threatening. Scientists emphasize that more research is needed.
