1) When astronauts go into space, they gain 2 inches height because their SPINES expand in microgravity. adventhealth.com/practices/adve….
2) Herpes reactivation is extremely common in astronauts. Herpes titres INCREASE the more time spent in space/on the space station. However, CD4+, CD8+, T-cells and NK cells all drop. hhv-6foundation.org/latest-scienti…
3) Astronauts on the ISS suffer from inordinately from RASHES and HYPERSENSITIVITIES. They are the MOST COMMON health problem. ncbi.nlm.nih.gov/pmc/articles/P…
4) Upon coming back to earth, astronauts must contend with orthostatic issues. They suffer from a "Pots-like physiology" : reuters.com/article/us-hea…
5) Astronaut Scott Kelly, who has spent the longest amount of time in space of any American, reacted with HIVES to everything he touched upon first return to earth. smh.com.au/lifestyle/astr…
6) Scott Kelly experienced significant cognitive impairment for at least 6 months after his return to earth. They stopped testing after 6 months. penntoday.upenn.edu/news/how-year-…
And there you have it! Food for thought and wonder about astronauts. (And, of course, the involvement of mechanical spinal stretch in herpes reactivation, decrease in immunological titers, Mast Cell Activation, and cognitive impairment.)
Footnote: Low-morning cortisol was noted in astronauts as well (see link above regarding herpes reactivation).
Second footnote: After tethered cord release and spinal fusion, the MCAS symptoms of @jenbrea and @jeff_says_that decreased dramatically.
