What does the human body do nine months in space

Spending time in space and an unmatched view of the planet Earth is an experience that many of us dream.

However, the human body developed to act in the gravity of the Earth. Therefore, the weightlessness of space can take years to overcome time completely.

After their eight-day mission riding on the International Space Station (ISS), the astronauts Sun Williams and Buch Wilmore are back to Earth, unexpectedly to remain nine months into force. Now, their recovery begins.

“Space is the most extreme atmosphere ever that humans have ever encountered and we have not only developed to handle extreme conditions,” says Professor Demian Bailey, who studies human physiology at the University of South Wales.

Entering space leads to changes in the human body – and initially it looks terrible.

“It sounds like a holiday,” a astronaut Tim Peak, who went to the ISS in 2015, says.

“There is an easy time coming to your heart.

“There is an easy time in your muscles and bones.

“You are swimming around the space station in this amazing zero-gurutavashan environment.”

Imagine walking on the bed in weeks and never getting up – this is really a technique Scientists use To examine the effect of zero gravity – and you begin to get the picture.

But when it comes to muscles, it is a matter of using or losing it.

Even the simple task of standing up uses muscles throughout the body so that you can hold it directly.

And this is not happening in microgravity on ISS.

The strength of the muscles takes to a different meaning when everything is practically weightless.

The heart and your blood vessels also have an easy time because they no longer have to pump blood against gravity – and they begin to weaken.

And bones become weak and more brittle.

There should be a balance between the chronic bone breaking cells and which are new to create.

But this balance is interrupted without reaction and resistance to working against gravity.

“Every month, their bone and muscles are going away about 1% – it is a boom in aging,” says Pro Bailey.

And it becomes clear when returning to Earth.

In the video below, astronauts require support to take out their body from capsules and on a stretcher.

Why all these astronauts go into space in tip-top physical condition.

Then, their routine involves a two -hour exercise – a combination of treadmill, cycling machine and weight – to maintain as much muscle and bone health as possible.

And now, listened and Butch will start an intensive exercise training program to regain their lost work.

Dr. Helen Sharman, who was the first Britain in space, Dr. Helen Sharman said, “Maybe it will take them a few months to make their muscles.”

The bone mass can take “a few years” until it is cured – but still, “there are subtle changes in the bone type that we reconstruct after returning to Earth that can never be completely normal”.

But this is just muscle and bone – space changes the entire body.

Even the types of good bacteria living in the US – microbiome – are replaced.

Fluids in the body are also shifted to microgravity.

Instead of pulling down the feet on the earth, the fluid moves towards the chest and face.

A puffy face is one of the first noticeable changes in the body.

But this can also cause inflammation in the brain and changes in the eye, including optic nerve, retina and even eye size.

And it can cause blurred vision and potentially irreversible damage to “Spaceflight-associated neuro-ocular syndrome”.

The microgravity also distorts the vestibular system, which you balance and understand how it is.

In space, no one is up, down or sideways.

It can be disorganized when you go up – and again when you return to Earth.

Tim Peak says: “To feel dizzy, the initial stage of re -acquiring your balance and placing strength to rotate normally, this is just two or three days.

“The first two or three days before Earth can be really punished.”
