Space pioneers have many negative effects during the time they spend in space, which requires a long renovation after returning to Earth. This has long been due to a mixture of weightlessness and increased radiation exposure, although symptoms do not follow any reason. Immune system disorders, infections and rashes are very common among astronauts – he writes 24. He is the IFLSCIENCE Quoting his article.
Dr. Rudolfo Salido and Nina Zhao, researchers at the University of California, San Diego, have led a group of verification in what could be responsible. The team asked ISS astronauts to take samples from many surfaces as they knew to find out what microbes are there.
Finally, 803 samples came much higher than the previous registry. Then they returned to the ground and studied.
As it turned out, most of the organisms of human skin, which is the gender of staphylococci, is the most common models, but not surprising, that the food made or consumed showed a greater diversity. However, due to the use of cleaning products, lands were almost missing from the ISS surface. Thus, environmental diversity is a small part of the Earth on ISS.
Currently, it is difficult to prove that this is a direct effect on weakening the immune system, but researchers have indicated that the increase in chronic inflammatory diseases in developed countries can be parallel to lower microbial exposure. According to researchers, research in the region can provide important lessons before the future, and a longer travel travel:
We need to start thinking about other beneficial living organisms that we need to send with astronauts to help them create sustainable environmental systems and benefit from everyone, as he writes.
