  • The phenomenon stems in part from changes in the regulation of blood pressure by the autonomic nervous system and the loss of about 20 percent of the volume of blood fluid - because under conditions of microgravity it is not necessary for systems to maintain blood pressure as body fluid spreads more evenly throughout the body. (weizmann.ac.il)
