The gravity and the human height

 The gravity and the human height

if human height is measured in morning and night then it found they are taller at morning then night this is maybe due to the gravity compressing cartilage bones of the body in the process of the whole day and when we are on bed whole night in resting position then these muscles relax and the hight becomes more at day compared to night.

In the case of astronauts, it is found that they are long after coming from space in comparison to when they are on earth. because in space there is no gravity so they become taler.
