Space travel, one of the greatest discoveries in the history of humanity, has gained an exciting momentum in recent years and studies in this field have gradually increased. A study by the University of Florida revealed the impact of space travel on astronauts.
Space travel negatively affects astronauts’ brains
Manned space travel, which started in 1961 with Yuri Gagarin from the Soviet Union, continues today. Since the beginning of this exciting adventure, there have been many questions about the effects of space travel on astronauts.
University of Florida researchers have released a report showing the impact of space travel on astronauts. While preparing this report, they analyzed the brain scans of 30 astronauts before and after space travel.
Scientists rolled up their sleeves: It’s time to grow food on the Moon!
Growing food on the moon has been one of the issues space companies have focused on for years. Scientists stepped in to find a solution.
Eight of the astronauts served in space for two weeks, 18 for six months, and the remaining 4 for a year. The team of researchers examined the before and after brain scans of these astronauts. It has been observed that the ventricles in the brains of people who have been in space for at least six months are enlarged.
The ventricles in the brain are cavities filled with cerebrospinal fluid. This provides the brain with protection, nutrition and removal of waste. The ventricles enlarge as fluid moves upward in non-gravity environments. When there is gravity, this fluid is evenly distributed throughout the brain.
According to the report, astronauts returning from space travel need more than 3 years for the ventricles in their brains to regenerate, that is, to heal. According to the researchers, the healing process begins after 6 months. According to this information, it is possible to say that the more time spent in space, the ventricles grow in this direction.
With this report, we have seen that short space travels do not have a serious effect on the person. This is good news for space tourism. So what do you guys think about this issue? You can share your views with us in the Comments section below.
