NASA’s Sonya Williams and Boot Willmore is facing a number of health challenges, as NASA’s leader is scheduled to return to Earth during this period, after nearly 9 months in space, and their lengthy stay causes health problems, such as muscle loss, weak bone, dizziness and feet problems.
How does the astronaut recover from these effects and adapt to the gravity of the Earth?
NASA’s leader, Sonita Williams and Bush Willmore, spent the long months of space, and it is expected that it will land by six o’clock in the evening on March 18, and although their return is an important achievement, their lengthy stay in space exposed them to many physiological changes, and affects a long time in space negatively on the human body, and will face Williams and Wilwmur many challenges Health while adapting to life on Earth.
Health challenges faced by astronauts after a long space mission
Dr. Achilish Yadaf, assistant director of orthopedics and joint replacement at Max Vicali Hospital, explained that the suspended astronauts can be exposed to the child’s feet syndrome, which is one of the less well -known health challenges, and this condition makes walking difficult for astronauts when they return to Earth, where astronauts float instead of walking, which means that their feet are not subject to pressure and usual friction On the ground.
Child feet syndrome
With the passage of time, the thick foot bones, which protect against daily corrosion, begin with softness and peeling, and this results in sensitive and smooth feet, very similar to the feet of children, and in the event of no gravity, the astronauts do not walk, so the skin of their feet does not grow thick, and upon their return their feet become very sensitive, which makes walking painful.
Low bone density and muscle loss
Among the most important challenges faced by astronauts after long space flights is the loss of bone density and muscle mass due to the lack of gravity, and according to NASA, astronauts may lose up to 1% of their bone density monthly in space, which makes their bones weaker and more fragile, and likewise, muscle atrophy occurs as a result of low use in small gravitational conditions, even with daily exercise, exercise, and daily exercise, and daily exercise, and daily exercise, with daily exercise, and daily exercise. Space pioneers suffer from a noticeable muscle loss, and they must follow an intense rehabilitation program upon their return.
Cardiovascular and brain health problems
Long -term space missions also affect the cardiovascular system and brain functions, and without the gravity of the Earth, the body fluids move towards the head, which increases pressure, affects vision and brain health, and NASA has identified a disorder called the neurological eye syndrome associated Gravity weakens the muscles of the heart, when returning to the ground, sudden change in blood volume may cause dizziness, nausea and fainting attacks.
