Introduction: Human beings have been evolving exponentially, however, the facets of this evolution occur in independent times despite being intrinsically linked, such as the technological evolution that evolved us in such a way that human biological evolution itself has become irrelevant to the standard of modern human life, the human being has been developing technologically very quickly, allowing us to idealize interplanetary travel, exploration of mineral resources from asteroids that pass close to Earth orbit, even the formation of other planets. Therefore, in this context, it is possible to identify a pattern that shows a greater need for human beings to undertake space travel more frequently and for longer, which also implies greater exposure to the risks and harm that this medium can offer. Objective: To show regulatory changes in the human body resulting from long exposure to the microgravity environment. Methods: The related study is a literature review of the systematic review type, where the following platforms were used as a search base: SciELO; LILACS; PubMED; Medline; ScienceDirect; Cochrane Controlled Trials Database; New England Journal of Medicine; ESSENTIAL; Circulation and Springer. Results: 18 relevant studies were found through the SciELO databases; LILACS; PubMED; Medline; ScienceDirect; Cochrane Controlled Trials Database; New England Journal of Medicine; ESSENTIAL; Circulation and Springer. Among these, 13 studies were eligible, since all studies addressed at least one of the inclusion criteria. Conclusion: It is concluded that there is a shortage of studies on this subject, due to a series of difficulties, from its applicability, collection, cost and control. However, the few studies found are unanimous regarding regulatory changes in the human body and how these directly impact their health.
