Question

Answer 2

Venturing into the environment of space can have negative effects on the human body.[1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia).[2] Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells, balance disorders, eyesight disorders and changes in the immune system.[3] Additional symptoms include fluid redistribution (causing the "moon-face" appearance typical in pictures of astronauts experiencing weightlessness),[4][5] loss of body mass, nasal congestion, sleep disturbance, and excess flatulence.
