Space flight produces positive physiological adaptations in the human body
the verdict
REFUTED
the evidence says no
confidence 2/100
Evidence overwhelmingly shows that space flight induces negative physiological consequences—such as bone loss, muscle atrophy, cardiovascular deconditioning, and oxidative stress—rather than positive adaptations.
