A new study found that the International Space Station (ISS) might actually be overly sterile. While having fewer microbes might initially sound like a good thing, it could actually be leading to health challenges astronauts often face in orbit.

Turns out, being too clean can be a bad thing. Scientists suggest the International Space Station (ISS) is so sterile that it may be making astronauts less healthy—and could even lead to problems like skin rashes,

The overly sterile environment of the International Space Station is missing important microbes, a new detailed map shows. If we want to live off Earth, we may need to take more of our bacterial frien

There are many potential dangers of life in space for astronauts including exposure to radiation, the mental health impacts of isolation and confinement, and the effects of weightlessness on the human body.

Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study published in the journal Cell suggests that these issues could be due to the excessively sterile nature of spacecraft.
