The International Space Station (ISS) is very clear, so astronauts return to Earth with a weak immune system – he writes Modern search On the basis guardian.
The researchers have found a conclusion that many microbes are missing from the sterile ISS on the ground in the soil or water and are beneficial to our immune system. This may explain that astronauts often have diseases associated with the immune system, such as rashes, lips, fungal infections or belt.
Researchers should write future space stations by maintaining these microbes there, and do not risk cleaning the station. Many astronauts participated in the research, with a total of 803 samples of different space station surfaces.
Based on these, human skin is responsible for many ISS issues, although it also depends on any part of the station. It is clear that the dining room and food preparation rooms contain food microbes, dominating urine and toilets. Of course, almost all surfaces were full of chemicals of detergents, so ISS is similar to hospitals.
