Space medicine is a developing medical practice that studies the health of astronauts living in outer space. The main purpose of this academic pursuit is to discover how well and for how long people can survive the extreme conditions in space, and how fast they can re-adapt to the Earth's environment after returning from space.
At extreme altitudes, above 7,500 m (24,600 ft) [383 millibars (11.3 inHg; 5.55 psi) of atmospheric pressure], sleeping becomes very difficult, digesting food is near-impossible, and the risk of HAPE or HACE increases greatly. [11] [14] [15] In the death zone and higher, no human body can acclimatize.
