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

The ISS’s microbial environment most closely resembles a hospital isolation room. It could be making astronauts sick.

The International Space Station may be too sterile – and the astronauts on board could benefit from it being a little dirtier, according to a new study. When astronauts spend time on the ISS, they often experience immune problems, skin disorders and other conditions.

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 in isolated space habitats could benefit from the intentional fostering of diverse microbes from humanity's evolutionary past, a new study suggests.

Some of the health effects astronauts suffer on the International Space Station (ISS) may not be a consequence of weightlessness, as previously thought, but of the ISS being too clean, a new study proposes.

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.
