According to ISNA, before humans can send humans to Mars extensively, it is a better idea to investigate the effects that prolonged presence in space can have on the human body.

These effects may be due to fluid changes due to a lack of gravity and brain function to re-learn how to move in a new unfamiliar space.

The human body has evolved to live under the conditions of the earth, and it is not surprising that if it is placed in a space other than the earth, it will suffer from various health problems.

constantly affects the body

Without gravity, which constantly affects the body, bones and muscles will lose volume over time.

That’s why astronauts on the International Space Station (ISS) use strenuous exercise Astronautics and the brain regimens to lose weight.

Cosmic radiation can also be a serious danger when we leave the Earth’s electromagnetic field.

Preliminary results from current NASA research show that long-term presence in space can actually change a person’s world.

The new study, conducted by researchers at the University of Michigan, focuses on the astronauts’ brains. The team examined MRI scans of 26 astronauts to conduct the study.

Twelve of the astronauts were members of the shuttle crew who stayed in space for two weeks, and the other 14 lived on the International Space Station for six months.

In all of these cases, the volume of gray matter in different parts of the brain both increased and decreased, and the more astronauts stayed in space, the more visible these changes became.

The movement of brain fluids due to the lack of gravity is an important cause of all health-related problems in astronauts, the most important of which is blurred vision.

On the other hand, an increase in gray matter often occurs in the parts of the brain that are responsible for controlling and sensing the legs.

Researchers still do not know exactly what happens in the brain when these changes occur, but they say the changes may be the result of new connections in nerve cells.

A follow-up study will examine the effects of these changes on brain cognitive function, as well as how long these changes last after returning to Earth.

What harm does space travel do to astronauts’ brains and eyesight?

Research shows that microgravity in space travel causes fluids in astronauts’ brains to rise, causing their heads to swell. This process also leads to impaired vision.
According to the Daily Mail, space travel causes astronauts to swell their heads and experience vision problems for months after returning to Earth.

Researchers have found that space travel changes the way fluids in the ventricles of the Astronautics and the brain brain change. The ventricles of the brain are actually cavities that allow fluid to flow through the brain.

They have found that microgravity causes fluid in these cavities to rise, causing fluid to expand slightly in the three ventricles of the brain.

Researchers studied the brains of 11 Russian male astronauts before and after a space trip to observe the effects of such a trip on the brain.

Each of these astronauts had spent six months in space. When they returned from this trip, their body arteries became smaller and returned to normal. But this process took several months.

“On Earth, gravity pulls fluids into the body towards the legs, but this does not happen in space,” said Angelique van Ombergen of the University of Antwerp in Belgium. As soon as a person enters the micro gravity, body fluids flow to the upper part of it. For this reason, the astronauts in the pictures appear to be swollen and large.

Research has shown that when astronauts return to Earth, their ventricular volume increases by an average of 11 percent.

In addition, the researchers observed a link between the volume of one of the four brain cavities and blindness. However, more observations are needed to prove this.

NASA has long been investigating a syndrome called Spaceflight Neuroocular Syndrome, or SANS. The organization is studying the effects of microgravity on astronauts’ vision.

About 30 percent of astronauts on short-haul space flights and 60 percent of astronauts on long-haul missions to the International Space Station report visual impairment.

Health hazards, as mentioned above, are important barriers to human life in space.

A new study shows that spending long periods in space increases the volume of astronauts’ brains.
Previous studies have shown that long periods in space cause vision problems in astronauts. And more than half of the members of the International Space Station have vision changes.

Scientists believe that increasing intraocular pressure plays a role in causing vision problems.

To do this, the researchers took brain scans of 11 astronauts before and after the space mission.

MRI results showed that the length of time astronauts were in space increased the combined Astronautics and the brain volume of their brains and cerebrospinal fluid. It is a fluid that flows in and around the empty spaces of the brain and spinal cord.

The combined volume

The combined volume is still high for up to a year after the astronaut returns to Earth, indicating permanent changes.

“In fact, an increase in brain white matter is responsible for the largest increase in the combined volume of brain and spinal fluid after launch,” said Dr. Larry Kramer, lead researcher at the University of Texas.

MRI scans also showed changes in the pituitary gland in astronauts, indicating that there is a lot of pressure inside the head when in space. The pituitary gland is located at the base of the skull and controls the function of many other glands in the body.

According to the researchers, one of the reasons for the changes observed in the eyes and brain is Astronautics and the brain due to the movement of fluid towards the head. Researchers are studying ways to deal with impacts in space.
