#FunFactFriday You are taller in the morning than at night! How can that be? As we go through the day, the cartilage in our knees and spine slowly compresses causing us to shrink a little. When we sleep at night the cartilage has a chance to rest and goes back to its normal size. On average we are about 1cm taller in the morning than we are at night. Astronauts experience this phenomenon more drastically when coming back from space! Without gravity their cartilage has plenty of time relax making them “grow” a few inches during their time in space.
