"During spaceflight there is a rise in secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system. In keeping with this, we find that astronaut's immune cells -- particularly those that normally suppress and eliminate viruses -- become less effective during spaceflight and sometimes for up to 60 days after."
Thanks!
- mc32 6y agoIs that during a whole stint in the ISS for example, or the mainly stressful parts during ascent and descent?
- T-A 6y agoFrom the actual paper [1]: "The shedding did not abate during the longer ISS missions, but rather increased in frequency and amplitude. These findings coincided with the immune system dysregulation observed in astronauts from shuttle and ISS missions." So it's not just ascent and descent.
