Scientists have particularly identified possible threats to people from space, and they have found evidence in astronaut blood.
Testing the blood of 11 astronauts (nine men and two women) who spent an average of six months at the International Space Station showed something very strange how low gravity can stop the flow of blood and even cause a reverse flow, writes Big Tnk.
The situation was particularly concerned with the upper body of people living in space. Long - term health applications are still under study, but this risk seems to be joining the list of risks already known to space loss and increased bone fragility.
The ultrasound estimates revealed that around the 50th day of the mission, seven crew members had stopped the flow of blood from internal artery, the largest neck artery, which circulates blood from the carotid supply area. Its function is to raise blood from the brain to the face and neck, and some astronauts have tried the opposite flow of blood.
The Dangers of Being in Space for Long
One astronaut also developed a clot in the artery while still in flight, and another faced blood clots after landing on Earth.
Confronting the flow of blood definitely does not sound desirable, and this discovery creates additional alarms regarding the dangers of long - term travel to space.
One of the directors of the study, Michael Stanger of the laboratory NASA at Houston Space Centre called the discovery <x0 unexpected”.
We didn't even suspect there could be a traffic stop and the opposite direction, this is abnormal. On Earth, we would immediately suspect a major impasse or a” tumor, he said.
Stenger attributes this issue to the lack of gravity, indicating the importance of monitoring physical changes in astronauts for many years to determine the long-term effects of human health exposure.
Some astronauts were struck with the face, since there is no gravity in attracting the fluid that circulates on the upper part of their body. Sometimes you may have arteries appearing in your neck or head area, especially in bald astronauts”, Stegner says.
It cites blood flow ban as the most disturbing aspect of discovery, saying it resulted in the formation of potentially fatal trumpet. But as for research itself, scientists also see it as an opportunity to predict risks and develop new treatments.
