TIL that astronaut Scott Kelly came back from living in space and was two inches taller than his identical twin brother.
For a little while. You are also taller in the morning than in the evening because your spine has no gravity crushing it all night. It took him about a year rather than 12 hours, though lol. More on reddit.com

Fun Facts About Astronaut Scott Kelly
February 21, 2023 - Kelly physically grew after leaving Earth. Without gravity, spinal discs are not being pushed down, and can thus expand, making astronauts taller. In space, Kelly grew 1.5 inches, but went back to his normal height when he came back to Earth.

Scott Kelly grew 2 inches taller whilst in space. Was that referring to his height only? What about arms, legs, hands, feet, and non-bone anatomy? - Quora
Answer (1 of 3): It was referring to his full spinal height. Everyone's height on earth actually decreases slightly through the day. In between your spinal discs there are fluid sacs for support. When you stand up your head and shoulders put axial pressure on your spine and cause these sacs to c...

What Caused This Astronaut to Grow Taller While Living in Space? - Texas Back Institute
December 29, 2017 - Did the effects of 1-year of weightlessness, the closed quarters or other factors cause Scott Kelly to grow an additional 2-inches? For the answer to this, Texas Back Institute spine surgeon Dr. Rey Bosita was asked for his professional opinion. “First of all, I would like to express my gratitude to astronaut Kelly for his willingness to spend a year of his life in outer space to do research for NASA. With regard to his increase in height, most likely, the discs in his back expanded some, and I am very interested to know how long he will remain taller,” noted Dr.

March 3, 2016 - Once he's back on Earth for a long enough time (still to be determined, but scientists estimate it can take a few months), gravity will bring him back to his normal height. In 2013, NASA launched a study that wanted to figure out what it was that caused astronauts to elongate by focusing on the spine. There are still some ongoing studies on the topic. Now that he's back, Kelly will be studied by scientists to look for other changes that may have happened to his body while in space, including any changes to his vision, bones, and brain.
