Astronauts Face Unique Health Challenges Upon Return from Space

March 18, 2025 - 19:03

When NASA astronauts Suni Williams and Butch Wilmore finally return home, they'll find their bodies changed after spending months on the International Space Station. The extended period in microgravity can lead to a variety of unexpected health issues, often referred to as "space ailments." One of the most peculiar conditions they may experience is known as "baby feet," a phenomenon where the astronauts' feet become swollen and soft due to the lack of gravitational pressure.

In addition to changes in foot structure, astronauts may also encounter muscle atrophy and bone density loss, making rehabilitation crucial upon their return. The body’s cardiovascular system can also be affected, with astronauts experiencing orthostatic intolerance, which can lead to dizziness and fainting when standing up after returning to Earth.

NASA continues to study these effects to better understand how long-duration spaceflight impacts the human body. As space travel becomes more common, addressing these health challenges will be vital for future missions and the well-being of astronauts.
