Why do human bodies grow taller in space?

What changes do the human body take place in space? You can grow taller!

Everyone knows that there is no gravity in space, and people's joints will be stretched, so the body will grow taller.

Because in the absence of gravity! The joints will pull apart, so the body will grow taller.

Without gravity in space, the discs of the human spine will expand, and all the joints will relax and the gap will increase.

In a weightless environment, the human bones are less stressed, and over time, the muscles atrophy and the bones become brittle.

There is no gravitational force in space, and our joints are not stressed, so our height is elongated.

Because there is no gravity in space, the gaps between the bones become larger, and the gaps in all the joints together feel noticeably taller.

This is due to the weightlessness of space at work. Because there is no gravity, there is no upper or lower division, the discs of the human spine will expand, and all the joints will relax and the gap will increase. The small expansion of dozens of joints adds up to a noticeable increase in the body.

Tiny expansions of dozens of joints are superimposed.

With no gravity, there is no hierarchy.

At the age of 43, Soviet cosmonaut Yuri Lomamanko returned to the ground after 326 days on the space station with a 1 centimetre taller. Why do people grow taller in space?

We know that the human spine bone is made up of 33 bones, most of which are separated by intervertebral discs, which are tough fibrous tissues that act as cushions to protect the spine. In space, because the effect of gravity on the spine no longer exists, the bones of the spine are stretched and extended, so after living for a period of time, people will grow taller.

Some people may think that if one day space travel is possible, wouldn't it be enough for a short person to grow taller by traveling for a year in a space tour? Actually, no. Because, this kind of growth in height is different from the normal body gain.

Normal elevation is the result of the accumulation of new periosteum growing at both ends of larger bones in the body. The height of an astronaut occurs in the specific environment of space, so when he returns to Earth, he will quickly return to his original height.

Xiao Ming said that he has grown taller in space, is it true? How do humans live in space? Let's find out!

A: Yes.

People will "grow taller" in space, mainly because the spine of the human body will increase. In the weightless environment of space, the compression of the vertebrae to the intervertebral disc disappears, the distance between the vertebrae increases, and the length of the spine will also become longer, so the height will also increase, and the increase is about 3% of the original height. When you return to Earth, you will regain your original height, but once you return to Earth, it will disappear after a few hours.

The human body is designed to survive in gravitational conditions, and when we go into space, we will experience all kinds of strange phenomena due to weightlessness. Many foreign astronauts have grown taller when they return to Earth from space.

It is true that humans grow taller in space, but once they return to the surface, they disappear after a few hours. This is because living in a weightless environment like the International Space Station elongates the spine slightly.

In a weightless environment, there is no gravity and there is no hierarchy. The spine will naturally stretch, all the joints will relax, the gap will increase, and the small expansion of dozens of joints will add up to make the astronaut grow slightly taller. After returning to Earth, gravity constantly exerts a pull on the spine, causing it to fall into place, and its height is restored.

The main reason for this is the lack of gravity in space, so the human skeleton will naturally stretch, and it will naturally look like the person will grow taller.

Because the gravitational pull in space is not as great as it is on Earth, there is no compression on the bones of the person.

In a weightless environment, there is less pressure on the human bones. So it will grow a little taller.

Maybe it's because there's no gravity in space, so you can pull it.

People get taller in space.

When people are on the earth, due to the gravity of the earth, the spine is in a state of compression, and in the vacuum of the universe, without the limitation of gravity, the spine will extend as much as possible, and the height will likely increase by about 2-3 cm, and the height will increase by about 5 cm at most.

In the space station, astronauts are in a state of weightlessness, which is also called a state of microgravity. Short-term exposure to microgravity can lead to spatial adaptation syndrome, a self-limiting nausea caused by a disturbance of the vestibular system.

Due to the sudden loss of gravity, the original sense of position on the head and feet has become any direction, and the person is always in a floating state, which causes nausea. However, after a period of adaptation, this feeling can be overcome.

Why do people float in space:

Because people will be weightless when they are in the space environment, and weightlessness means that the object loses the effect of the gravitational field, when the object is in a weightless state, the object will not be affected by any external gravitational field except for its own gravity, so the person will float.

Why do people get taller when they go to space?

Cosmic travel can make a person taller. American astronauts Gerald Carr, Edward Gibson and William Pogue were all 5 centimeters taller than they had left when they returned to Earth from Space Laboratory 3 after completing an 84-day space mission in 1974.

It is normal for people living on Earth to have daily changes in height. The human spinal disc shrinks every day due to the attraction of the earth. At night, some adults can measure their height by more than 2 centimeters, and after a night's rest, the spine will stretch and the height will return to its original shape.

But the astronauts working in Laboratory 3 don't get a taste of the daily contraction. In a gravity-free environment, their spinal discs absorb the added fluid from the surrounding bloodstream, forcing the spine to expand, which in turn makes the astronaut taller. However, within a few days of their landing, they returned to their original height.

When people are on the earth, due to the gravity of the earth, the spine is in a state of compression, and in the vacuum of the universe, without the limitation of gravity, the spine will extend as much as possible, and the height will likely increase by about 2-3 cm, at most about 5 cm.

Physical fitness, as a basic condition for a person's survival, is indispensable in the training process of astronauts. In order to prepare for the Apollo Alliance program, the Soviet Union required its astronauts to ride 1,000 kilometers by bicycle, 3,000 kilometers by ski, and run more than 200 kilometers of cross-country in a year and a half of training. In order to improve the endurance of astronauts, the Houston Space Center in the United States once asked astronauts to wear 80-kilogram spacesuits and walk 30 kilometers a day in the hot Florida desert.

Introduction of the astronauts:

An astronaut is a person who has been trained to fly a spacecraft or conduct scientific research during space flight. Called an astronaut in China and an astronaut abroad, Yang Liwei was the first person in China to enter space, and the space flight time was 21 hours.

There are two types of astronauts, professional and non-professional, generally divided into pilots, mission specialists and payload specialists, or commanders, pilots, shipboard engineers and flight engineers. Astronauts are pioneers in opening up the road to space, and being an astronaut requires high dedication, a high level of knowledge, extraordinary work ability, excellent environmental endurance, good psychological quality and healthy physical conditions.
