A viral video of space-returned astronaut and Group Captain Shubhanshu Shukla learning to walk again on Earth has left many surprised. After spending approximately 18 days abroad on the International Space Station, Shukla, who returned safely on July 15, can be seen re-learning how to walk. “I have received a lot of messages regarding my health and wishing me a speedy recovery. I want to thank you all and also give an update. Experiencing microgravity, our body goes through several changes, like fluid shift, heart rate, balance readjustment, and muscle loss. These are adaptations to the new environment. Once the body gets used to this and we return to gravity, these adjustments happen once again,” Shukla said in an Instagram post.Shukla, who can also be seen doing balancing stretches and postures as well as running on a treadmill, continued, “Though it varies for all astronauts, the body soon starts adapting to its new environment. I was surprised to observe the pace with which our body can adjust to new settings. In the pursuit of the unknown(space), you get to know more about yourself.”Taking a cue from his candid admission, let’s ask experts how long it takes for the body to adjust.When astronauts return from space, walking again on Earth isn’t as easy as it seems, said Dr Anup Khatri, senior consultant, orthopedics, Gleneagles Hospital, Parel, Mumbai.“It will take some time to get used to walking again. In microgravity, muscles and bones don’t work as hard, leading to weakening. The body must readjust its balance, blood flow, and coordination patterns when in space. After even short space missions, astronauts often tend to experience dizziness, muscle fatigue, and balance issues,” said Dr Khatri.

Depending on the mission length, it can take a few days to several weeks to fully regain strength and coordination and walk again,” said Dr Khatri.Also Read | All about Spaceflight Associated Neuro-ocular Syndrome, the eyesight issue Sunita Williams is likely facing in spaceRehabilitation is a crucial aspect of recovery.
