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.
Human presence in space. Human presence in space (also anthropogenic presence in space or humanity in space) is the direct and mediated presence or telepresence of humans in outer space [1] and in a broader sense also on any extraterrestrial astronomical body. Human presence in space, particularly through mediation, can take many physical forms ...
An educational video about the challenges to sex posed by a zero-gravity environment. The conditions governing sex in space (intercourse, conception and procreation while weightless) have become a necessary study due to plans for long-duration space missions, as well as the future potential accommodation of sexual partners aboard the International Space Station (ISS).
Yahoo Life asked astronauts Jasmin Moghbeli and Andreas Mogensen — who are currently living and working on the International Space Station — about some of the health challenges of space.

Astronauts with missions aboard the space station are generally gone for about six months, ... the Starliner astronauts are living among the seven members of Expedition 71 who arrived in April.
Sleeping in space is part of space medicine and mission planning, with impacts on the health, capabilities and morale of astronauts. Human spaceflight often requires astronaut crews to endure long periods without rest. Studies have shown that lack of sleep can cause fatigue that leads to errors while performing critical tasks.
Spaceflight osteopenia. Spaceflight osteopenia refers to the characteristic bone loss that occurs during spaceflight. Astronauts lose an average of more than 1% bone mass per month spent in space. [1] There is concern that during long-duration flights, excessive bone loss and the associated increase in serum calcium ion levels will interfere ...
