Astronaut Sunita Williams will have these health problems after returning to Earth.
What health problems will Sunita Williams face after returning space- NASA astronaut Sunita Williams has safely returned to Earth after a 17-hour journey in space after a long 9-month journey. Do you know that Sunita will have to face many health problems on Earth due to being in zero gravity. Being in space for a long time has a profound effect on the astronaut’s body. As a result, it takes them a few months to get back to normal.
According to health experts, astronauts experience many changes in their bodies after spending a long time in space. Since there is no gravity in space, they start to float. Due to this, the astronauts’ muscles become weak. Due to this, astronauts have problems sitting, standing, walking, and even seeing. you also read this What Is The Salary Of Astronauts?
Walking problems: NASA astronaut Leroy Chiao said that after returning to Earth, Sunita Williams and Butch Wilmore had walking problems, which are called ‘baby feet’. When a person stays in space for a long time, the thick skin on their feet is destroyed. As a result, their legs become soft and weak like those of a small child. Due to the lack of gravity, the legs become weak and have difficulty walking and maintaining balance.
Effects on muscles and bones: Muscles shrink due to microgravity in the space station. Similarly, bones lose strength due to the lack of gravity on Earth. There is a possibility of breaking bones after returning to Earth. On Earth, it takes about 4 years for muscles and bones to return to normal.
Eye problems: Due to Earth’s gravity, blood flow in the human body is directed downward. But in space, this process is disrupted, and blood clots form in the head. The excessive accumulation of blood causes fluid to accumulate at the back of the eye and around the optic nerve. This causes astronauts to experience some vision problems, such as blurred vision and structural changes in the eye.
Heart problems: Williams and Wilmore are also at risk for heart disease due to their long time in space. Their heart rate can change, which can lead to heart-related problems. “The heart doesn’t work as hard in space, which can weaken the muscle. The heart is affected when you return to Earth,” said James Thomas, NASA’s Moore Chair in Cardiovascular Imaging and Ultrasound Principal Scientist and senior author of the study.
Speech problems: Space is a weightless environment. Being here weakens the muscles involved in speech, such as the tongue, jaw, and throat. This can cause astronauts to have difficulty speaking. But everything returns to normal within a few days.
Decreased immunity: Not only that, researchers have found that astronauts’ immunity also decreases during space travel. The number of white blood cells decreases.
Impact on mental health: After spending a long time in space, it may take a few days for the astronauts to adjust to the environment on Earth. During this time, they may experience anxiety, depression, and feelings of loss. They may struggle to lead a normal life. Along with this, they may also experience problems like dizziness.
