science of height change

Did you know that your height changes throughout the day? Most people believe that their height remains constant, but according to scientific facts, gravity Due to the effect of , we become smaller by 1-2 cm a day. Let us understand how astronauts grow taller in space.

Changes in morning length and space

According to NASA, we are tallest when we wake up in the morning, because lying down overnight causes our spine to expand. But in space this change is even greater.

effect of microgravity

According to a NASA study, astronauts’ height increases by an average of 3 percent in microgravity, especially in the first 3-4 days. This growth occurs mainly in the spinal cord.

gravity pressure

On Earth, gravity keeps pressing the discs of the spine, whereas in space there is no such pressure due to which the discs expand. This affects height, sitting position and position of shoulders.

Kate Rubins Experience

NASA said that Astronaut Kate Rubins, who was part of Mission X, had an ‘earth height’ of 171 cm, which increased to 174.4 cm in space. When she returned to earth, due to the effect of gravity her height again became the same.

Understanding physical changes

Astronaut Mike Barrett and Principal Investigator Sudhakar Rajulu in NASA’s Human Research Program explained in a video how the body changes in space. To understand this change, NASA has published ‘What’s your space height?’ Started a fun activity named.

Anthropometry and Design

This activity is to anthropometry, in which the NASA team decides spacecraft, space suits and other designs by taking measurements of astronauts. As height increases in space, the shoulders become higher, making it easier to reach higher things.

Adjustment in spacecraft

Astronauts support themselves while working in space by placing their feet in floor stands. Many features in the spacecraft are adjustable, as altitudes vary during launch and return.
