A method for preparing space travelers to spend an extended period of time in space

Astronauts traveling into space and a few days from now, perhaps relatively soon, to Mars will face a wide variety of challenges. As a result of solar radiation and weightlessness, the human body will be exposed to several challenges.

According to an article on SpaceRef.com, Dr. Lex van Loon of ANU's Medical School explains that our bodies are not designed for such an environment and we are not used to it.

“ The weightlessness experienced in zero gravity space travel could cause changes in your blood vessel structure or heart strength during space travel to Mars, which takes about six to seven months.

The human heart isn't accustomed to the low gravity environment of space or another planet such as Mars, notes colleague Dr. Emma Tucker, an astrophysicist, and emergency medicine registrar.

As a result, our heart is not having to work as hard pumping blood through our bodies, which leads to it becoming lazy, which can lead to serious consequences if not dealt with early on.

“As you're sitting on Earth, gravity has a tendency to pull fluid to the bottom half of your body, which explains why some people feel their legs begin to swell up toward the end of the day after some time spent outside.

As you go into space, gravity dissipates, which means the fluid shifts to the top half of your body, fooling your body into thinking there's too much fluid,' Tucker says. 

As a result, you start going to the toilet frequently, you lose fluids, you don't feel thirsty, and you don't drink as much, which leads to being dehydrated in space. Astronauts may do this for this reason... they feel faint after returning to Earth.

As a result of space travel, this is quite a common occurrence, and the longer you remain in space, the higher the chances are that you will collapse when you return to gravity when you return to Earth gravity.

As a result, it is extremely important to be able to predict in advance whether an individual will be able to tolerate the challenges and effects of low gravity during space travel and assess their ability to do so.

The astronauts are not able to access hospitals during their time in space if they get into problems with their health -- this is due to the lack of local hospitals. 

The article discussed here examines how different space travelers will react to the environment of space based on a mathematical model developed at ANU.
