According to NASA, astronauts can face different health problems - from weaker bones and muscles to vision issues and 'baby feet' - as their bodies adjust back to the planet’s gravity.
The news reporter also discussed the risks of osteoporosis as the astronauts' bones become 'about 1% less dense for every month that they are in space.' Not to mention that astronauts also get taller in space due to their 'spinal column expanding' but once they return to Earth, it contracts again which can lead to back issues.
Additionally, due to long-term radiation exposure, astronauts can be at a heightened risk of radiation sickness, cancer, central nervous system effects and degenerative diseases, NASA described.
"In low earth orbit where the ISS is, astronauts are at least partially protected by the magnetosphere that protects Earth from the radiation exposure of deep space," noted Dr. Rihana Bokhari, acting chief scientific officer at Baylor College of Medicine's Translational Research Institute for Space Health.
