Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions, according to NASA research published in Frontiers in Microbiology. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond.
[...] "NASA astronauts endure weeks or even months exposed to microgravity and cosmic radiation—not to mention the extreme G forces of take-off and re-entry," says senior author Dr. Satish K. Mehta of KBR Wyle at the Johnson Space Center. "This physical challenge is compounded by more familiar stressors like social separation, confinement and an altered sleep-wake cycle."
[...] "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."

could it be that something in fermented cabbage neutralizes cortisol?
so i guess it's either blister lips or stinky food ^_^

Maybe. Or, as they seem to be assuming, it could be radiation. Or it could just be zero G. That is known to have some chemical effects, as, e.g., you don't get convection.
The diet hypothesis would be relatively easy to check. Monitoring cortisol levels only a bit more difficult. The other possibilities....seem either more difficult or more dangerous.

You're supposed to feed the kimchi to some cuttle fish before you eat them raw.
