What One Year Of Space Travel Does To The Human Body

Everyone is concerned about how being in space affects your health, but I’m over here worrying about how fast the Internet is on the ISS.

Without the forces of gravity to help circulate air inside the orbital laboratory, the carbon dioxide its residents exhale can form an invisible cloud around their head, which can lead to headaches. In weightlessness, the fluids in the human body float upward and clog the sinuses, making astronauts’ heads feel congested and their faces appear puffy. Their skeletons become useless; bones don’t need to support muscles in microgravity, so they start losing minerals and regenerating cells at a slower pace.
