First, there was learning that we are our tallest when we first wake up.

Now, it’s time to learn that astronauts get taller in space!

From Scientific American:

Astronauts in space can grow up to 3 percent taller during the time spent living in microgravity, NASA scientists say. That means that a 6-foot-tall (1.8 meters) person could gain as many as 2 inches (5 centimeters) while in orbit.

Past studies have shown that when the spine is not exposed to the pull of Earth’s gravity, the vertebra can expand and relax, allowing astronauts to actually grow taller. That small gain is short lived, however. Once the astronauts return to Earth, their height returns to normal after a few months. But still, scientists haven’t been able to examine the astronaut’s spinal columns when experiencing the effects of microgravity until now. 

Pretty cool, right? Read more HERE!
