Astronauts float weightlessly in space, and the condition of weightlessness is something many would love to experience. However, in addition to producing both physical and psychological stress, a trip into space affects the core body temperature of astronauts. Researchers from Charité – Universitätsmedizin Berlin have observed that body temperature rises during weightlessness, and that, even at rest, astronauts’ body temperature is approximately 1°C above the normal value of 37°C (98.6°F). Results from this study have been published in the journal Scientific Reports.
