Space fever: Weightlessness increases astronauts' body temperature

more »
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).
