Detailed explanation-1: -Without the proper diet and exercise routine, astronauts also lose muscle mass in microgravity faster than they would on Earth. Moreover, the fluids in the body shift upward to the head in microgravity, which may put pressure on the eyes and cause vision problems.
Detailed explanation-2: -If you stay for a long time in space, your muscles and bones will weaken, primarily in the legs and lower back. Gravity always acts on you while you’re on the earth, so even if you’re not really conscious of resisting gravity, you’re always using the muscles of your lower body.
Detailed explanation-3: -The International Space Station circles the earth at an altitude of more than 300 km in an environment characterized by high vacuum, microgravity, extremes of temperature, meteoroids, space debris, ionospheric plasma, and ultraviolet and ionizing radiation.
Detailed explanation-4: -Radiation. Isolation and confinement. Distance from Earth. Gravity (or lack thereof) Hostile/closed environments. Human research essential to space exploration. 08-May-2019
