Do astronauts really grow tall in space!

When we reach a certain age, we see that the growth in height stops. But it is not like that in space, if you go there, the height increases, which is strange to believe, but this is literally true. An example of this is the astronauts who have travelled to space so far. Originally the same height, NASA astronaut Scott Kelly was two inches taller than his identical twin brother Mark after living for nearly a year aboard the International Space Station

When on the ground, gravity puts pressure on the discs in our spine. This level of gravity in space makes them stretch. Astronauts will grow a few centimeters taller because of this. If you return to the ground again, you will reach the original height. That is why many astronauts say that they are facing back pain problems after returning to earth. Another interesting thing is that space radiation causes slight changes in the DNA of many astronauts.
