What nine months in space does to the human body | Global News Avenue

Spending time in space and having an unparalleled vision of the earth is an experience that many of us dream of.

However, the human body evolves to play a role in the gravity of the earth. Therefore, it may take years for space weight loss to fully recover.

Astronauts Suni Williams and Butch Wilmore returned to Earth after an eight-day mission on the International Space Station (ISS) unexpectedly became a nine-month execution stay. Now, their recovery has begun.

Professor Damian Bailey, who studies human physiology at the University of South Wales, said: “Space is by far the most extreme environment that humans have encountered, and we have not evolved to deal with extreme conditions.”

Entering the space changes the body – it feels great at first.

“It feels like a holiday,” astronaut Tim Peake traveled to the International Space Station in 2015.

“Your heart is relaxed.

“Your muscles and bones are relaxed.

“In this wonderful zero gravity environment, you’re floating around the space station.”

Imagine spending weeks hanging out in bed without having to get up – it’s actually a technique Used by scientists Investigate the effects of zero gravity – you start getting pictures.

But when it comes to muscles, this is the case of using it or losing it.

Even simple standing behaviors still use the muscles of the whole body to keep you upright.

This did not happen in the microgravity of the International Space Station.

Muscle strength has different meanings when everything is actually lost.

The heart and your blood vessels also have easier time because they no longer need to pump blood for gravity—and they start to weaken.

And the bones become weaker and more brittle.

The cells that break down old bones should be balanced.

However, this balance is destroyed without feedback and resistance against gravity.

“Every month, about 1% of bones and muscles wither – this is accelerated aging,” Professor Bailey said.

This is obvious when returning to Earth.

The video below shows that the astronaut needs support to extend his body out of the capsule and then enter a stretcher.

All of this is why astronauts rise in the physical state of cutting-edge.

Their daily routine then involves two hours of exercise – a combination of treadmills, bikers and weights – to keep as much muscle and bone healthy as possible.

And now, Suni and Butch will launch a intense exercise training program to restore lost features.

“It may take several months to build muscle mass,” said Dr. Helen Sharman, the first British man in space.

It may take “a few years” to recover until it recovers – but even then there are subtle changes in the type of bone we will rebuild upon returning to Earth, which may never fully return to completely normal”.

But it’s just muscles and bones – space changes the entire body.

Even the type of good bacteria in life – the microbiome – changes.

The fluid in the body will also move in microgravity.

The liquid was not pulled toward the legs, but drifted towards the chest and face.

A swollen face is one of the initially noticeable changes in the body.

But this can also cause the brain to swell and change on the eyes, including the optic nerve, the retina and even the shape of the eyes.

And this “space-related neuroophthalmic syndrome” can lead to blurred vision and potentially irreversible damage.

Microgravity also distorts the vestibular system, which is how you balance and perceive which way.

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

It can be confusing when you ascend – when you return to Earth again.

Tim Peake said: “The initial stage of stopping feeling dizzy, rebalancing and having the power to walk normally is only two or three days.

“The first two or three days on Earth may be really a punishment.”
