Description
Summary:This article is a literary review focused on the problem of the stress-effect of microgravity. Based on the all-round analysis of data from manned missions and space experiments with rats it is concluded that microgravity as a permanent factor of space flight does not produce an intense chronic stress in either humans or animals. On the other hand, microgravity is responsible for deconditioning of a number of vital systems and of the organism as a whole. On return to Earth, the deconditioned bodies of humans and animals exaggerate the usual terrestrial loads due to gravity forces and respond by acute gravitational stress.
