"Astronauts are typically among the fittest individuals on the planet, yet this study shows that even they experience substantial sinonasal complaints in space."
"Imagine what happens when civilians with preexisting conditions start travelling to space."
"Of these, 85 percent experienced at least one 'sinonasal complaint' - far higher than you would expect from a healthy sample group."
"The symptoms can have a measurable impact on crew performance, and are worsened during extra-vehicular activity (EVA) - spacewalks."
A study investigated sinonasal complaints among astronauts on the International Space Station from 2000 to 2019. Out of 71 astronauts, 85 percent reported sinonasal issues, with 75 percent experiencing nasal congestion. These complaints are not caused by infections but are effects of microgravity, which disrupts fluid drainage. The symptoms notably worsen during spacewalks, affecting crew performance. This raises concerns for civilians with preexisting conditions traveling to space, highlighting the necessity of addressing health issues beyond just physical fitness in astronauts.
