Astronauts undergo rehabilitation after returning from space

Astronauts returning from space need special care to help them adjust back to Earth. After landing in the Gulf of Mexico on March 19, four astronauts began their rehabilitation process. They included Sunita Williams and Barry Wilmore, who had spent nine months on the International Space Station (ISS). Living in microgravity affects the body in different ways. It causes fluids to shift towards the brain, reduces muscle tension, and lowers bone density. To counter these effects, astronauts follow strict exercise and diet routines while in space. NASA has designed programs to help them manage stress during their missions, which can last several months. Upon their return, astronauts must undergo a series of medical tests and physical exercises. NASA has specific guidelines for monitoring their health before, during, and after spaceflights. These guidelines include evaluations at various intervals after the mission, with ongoing check-ups for specific health issues like deep-vein thrombosis. After landing, astronauts engage in a personalized rehabilitation program. Most astronauts typically return to their pre-flight fitness levels within 45 days, but some may require additional time based on their recovery. The rehabilitation begins with physical exams and includes exercises to safely readjust their bodies to Earth's gravity. The rehabilitation process includes daily physical activities designed to improve strength, endurance, and flexibility. Exercises may involve cycling, jogging, and even playing games in water to ease their transition. Medical professionals closely monitor their progress until they are fit to return to their regular duties.
