NASA astronaut Sunita Williams shares surprising effects of space travel on the body

In space, hair and fingernails grow faster, spine expands, and body gets taller

Astronauts experience bone density and muscle mass loss due to microgravity
NASA astronaut Sunita Williams has shared fascinating insights into the effects of space travel on the human body. In an old interview, she revealed that in space, hair and fingernails grow faster, and the spine expands, making the body slightly taller. However, these changes reverse once back on Earth.
Williams also highlighted the concerns of space travel, including space anemia, bone density loss, and muscle mass loss. To counteract these effects, astronauts exercise rigorously with specialized equipment, including treadmills and weightlifting.
Despite mitigation methods, Williams noted that radiation exposure remains a concern, increasing the risk of cancer and acute radiation sickness.
