Scientists: Changes occur in the blood circulation of astronauts during the first days of zero gravity

It became clear to Russian scientists that in the first three days of the flight, the blood of astronauts in zero gravity rises to the upper part of the body, and on the sixth day, blood circulation returns to normal.

The press office of the Russian Ministry of Education and Science said in a statement: “In the first two or three days in conditions of zero gravity, the astronaut witnesses his blood rising to the upper part of his body, after which the mechanisms regulating blood distribution are activated, and on the sixth day of the flight, blood circulation returns to normal. In general, "More pronounced changes occur in the temporal region of the head and lower extremities in microgravity conditions during the second and third days of flight."

It is noteworthy that these experiments, called LASMA, have been taking place in the Russian sector of the International Space Station since December 2021, and are scheduled to end in 2025, in which researchers from the scientific institutes of the Russian Academy of Sciences, the Ministry of Health, Ariol University, the Center for Astronaut Preparation, and the LASMA Scientific Foundation participate. Productivity.

Russian astronaut Alexander Misurkin and Japanese astronauts Yusaku Maezawa and Yuzo Hirano volunteered to participate in these experiments.
