Unable to walk, body destroyed! Astronaut tells of the brutal effects of living in space for 136 days
Astronaut Jack Fischer has shared his experience of a 136-day space mission. In 2017 that took a toll on his body, from walking problems to cardiovascular problems to the long-term effects astronauts have to deal with.
The body’s adaptation to weightlessness
Fisser began by explaining that in weightlessness. The body’s balance and equilibrium systems are disabled due to the absence of gravity. So, upon returning to Earth, these systems must be readjusted, causing feelings of dizziness and unsteadiness. He described walking back as being like being a toddler again.
Cardiovascular changes
In space, blood is distributed more evenly throughout the ทางเข้า UFABET สำหรับสมาชิกใหม่ สมัครวันนี้ รับโบนัสฟรี body because there is no gravity pulling blood down to the legs. But when you return to Earth, the heart must adjust to pump blood with gravity again, which can cause dizziness or fainting.
Recovery after returning to Earth
Fischer said it took him about 45 days to get back to normal after returning to Earth, during which time he had to undergo physical therapy and exercise to restore his muscles and bodily systems.
However, studying the effects of long-term space travel is crucial for planning future missions, such as those to Mars. Data from astronauts like Fischer helps scientists understand and prepare measures to protect crew health on long-term missions.
