What effect does Space have on the human body?
Human beings are affected and shaped by Earth's gravity and this force can influence our physiology in various ways. When in Space, in a microgravity environment, the human body's structure and physiology changes. This can have many consequences, such as alterations in the functioning of cardiovascular, haematologic and immune systems, and especially causing bone loss and muscle atrophy. Adaptation to this kind of environment is difficult and imposes huge challenges. The majority of astronauts also experience space motion sickness at some level.
