Research progress on the effects of microgravity and space radiation on astronauts’ health and nursing measures

Abstract With the development of human space technology, more and more astronauts fly into space. With the rapid development of commercial aerospace, more ordinary people will go to space for sightseeing. However, it should not be ignored that microgravity, space radiation, relative geometry, and orbit of space stations have various effects on the health of astronauts. In recent years, scholars in various countries have made considerable research progress in this field. This article analyzes the research history and current situation of this field, including the individual effects of space radiation, microgravity, orbit, and relative geometry, as well as their comprehensive effects. In addition, various nursing measures have been investigated.
