NASA’s astronaut withdrawal: Can nine months continuously change the body physically and mentally in space?
Sunita Williams and Barry Wilmore have successfully returned to Earth after spending nine months in space. However, according to experts, this journey will also take heavy toll on both their physical and mental health. From eye light to immunity, skin, bones, and even increase the risk of cancer, read what are the dangers in front of NASA astronauts.

NASA astronaut Sunita Williams and Barry Wilmore, which took into space, lasted longer than planned. On June 5, 2024, the two returned to the International Space Station (ISS) after completing 288 days or nine months at the International Space Station (ISS).
According to experts, space travel, whether it is for short term or long, can pose a significant risk for both physical and mental health. And for both Williams and Wilmore, when it comes to their good, tough challenges are going to happen.
What is the effect of living in space on the human body?
Experts say that spending a lot of time in microgravity can be cruel on the body. Without pulling the gravity of the Earth, the body can suffer from shrinking muscles, and weak bones can be transferred to physical fluids.
Astronauts also lose muscles rapidly as they do not use their legs to support their weight in space. Doctors say that because of this, their bones become delicate and even reduced to 1 percent of their bone per month, which is equal to an entire year of aging on Earth.
Radiation increases the risk of cancer
According to experts, radiation contact for astronauts in space is a major concern. Even though the ISS is preserved by the Earth’s magnetosphere, astronauts on missions extending more than six months receive more than ten times the radiation on the earth.
And so, prolonged risk is associated with high cancer risk and potential cognitive decline.
How are your body parts affected in space?
Body mass
According to NASA, astronauts lose about 20 percent of their body fluids and about 5 percent of their body mass when in space.
Muscle loss
Space in space leads to muscle atrophy
skin
The skin of astronauts can be thin and can easily tear with a little itching.
eyes
Spce microgravity can spoil the vision, and radiation increases the risk of cataract.
Psychology
According to doctors, radiation causes slow brain damage and it can accelerate the onset of Alzheimer’s disease. The space migration can also disrupt orientation, which leads to severe motion disease or vertigo.
cardiovascular health
Extended and prolonged stay in space can slow down breathing and produce the production of red blood cells, which can lead to cardiac arrhythmia.
Immune level
The space migration also weakens the immune system due to radiation risk.
Skeleton health
Doctors say that space stay also distorts the skeletal system, causing at least one percent bone loss every month. Astronauts become long as they expand in their spine orbit.
Does the body once recover back to Earth?
Experts say that even after returning to Earth, the human body does not immediately return to the original, as both physical and mental stress of months can be harmful.
Even when the astronaut’s bodies start reading for gravity, they experience issues:
- Balance problems
- Dizziness
- Improvisation
- Weak and slow heart function
Most astronauts may also face long -term health risks including cancer, nervous damage and degenerative diseases. Doctors say that the immunity of astronauts can return to normal level after at least two weeks, their body may begin to revive and the production of red blood cells becomes normal.
A month later, the improvement in the muscles also occurs near the complete and pre-objection levels and the skin redevelopment begins. However, the risk of bone fracture lasts for at least six and months.
