Weightlessness In Space

Weightlessness In Space

Space fever: Weightlessness increases astronauts' body temperature. Astronauts float weightlessly through 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 our core body temperature. Researchers have observed that astronauts run hot when exposed to weightlessness, and that, even at rest, their body temperature is approximately 1°C above the normal value of 37°C (98.6°F).
