Space travel is not just fun, it turns out traveling in space increases the brain.

"Be careful what you wish for," is the old adage, and it also applies here. A flight to Mars is a scenario that all of humanity has dreamed of for centuries, but the consequences may not be very pleasant.

First, astronomers must make sure that space travel is completely safe for people, even in their spacesuits. However, new research shows that exploring our universe can cause some unexpected changes for humans - an increase in brain size.

Researchers led by Dr. Larry A. Kramer performed MRI scans of the brains of 11 astronauts before they went to the International Space Station. The same astronauts were scanned again after they returned from space travel. Analyzing these two different situations, the scientists concluded that areas of the astronauts' brains were physically expanding during space exploration. The culprit for this is none other than the lack of gravity that the astronauts experienced after they left Earth.

Dr. Kramer said the following:

“When you are in microgravity, fluid such as your venous blood no longer accumulates in the lower extremities, but is redistributed towards the head.

This movement of fluid towards your head may be one of the mechanisms causing the changes we see in the eye and intracranial region.”

A new article exploring the brain of astronauts has been published in the journal Radiology.
