Humans have evolved alongside microbes in Earth's environment that help strengthen our immune systems. But sterile living conditions can reduce that beneficial exposure

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.

The International Space Station is too clean, and making it “dirtier” could improve astronauts’ health, claims new research. They often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space.

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.
