Space sleeping bag could be the solution for astronauts to stop suffering from eye damage

live or travel to Mars They remain a dream and an outstanding task for researchers who will not give up until they achieve it. However, they are not only focused on the task of building a space rocket Equipped with enough to carry astronautsBut in everything travel involves: where to sleep and take care of your health.

It is true that without space ship You will not be able to complete Mission to Mars or any other destination outside the earth, However, another essential part is that your crew is comfortable enough and has all the necessary accessories because the trip, according to some estimates, will take more than nine months.

In this way, so that it is Astronaut fitness To be kept for as long as they will be in the space, they must have a place to sleep properly, which also means that this space must take care of their eyes.

Researchers have found that astronauts’ eyesight is significantly reduced after they return to Earth. This led them to discover that zero gravity affects their vision.

according to BBC, NASA found that a file lack of gravity Contributes to the emergence of astronauts vision problems, because it makes Body fluids put pressure on the eyeball.

This evidence has been compared to more than half of the astronauts who have spent at least six months in International Space Station (ISS). Some had difficulty reading or needed help completing their exams.

It turns out that a file Weightlessness It causes body fluids to build up in the head, causing the eyeball to be under greater pressure, resulting in a condition called . without Or also known as Optic Nerve Syndrome Associated with space flights that affect the optic nerve and impair vision.

One such case was recorded in 2005 with astronaut John Phillips who arrived at the International Space Station with 20/20 vision (ideal), however, six months into the mission, returned to Earth with 20/100 vision.

Hence, they are worried about that Journey to Mars, which would be much longer, could severely affect the eyes of space missionaries.

In this sense, they have developed the Space Bed Project to help astronauts maintain their visual health. Oddly enough, it’s not targeting glasses, helmets, or anything else, but rather a sleeping bag.

Although the astronauts will need to sleep comfortably, it is now also important to maintain their visual health, which is why they are trying to solve the problem with a bag that makes a difference in pressure.

Its design is peculiar, as it is attached to the waist and keeps the astronaut’s legs hidden to create a different pressure from the rest of the body; this way, The fluid is attracted to the feet And not in the head.

This project is still under development, because first they want to polish it to give the best result for astronauts who are venturing through space. Although the goal at the moment is eye care, they also want to help others Typical diseases of astronauts such as atrial fibrillation.
