A year in space could change your life.
Scott Kelly’s mission was longest regarding her past ones. Astronaut Kelly along with his Russian colleague, a cosmonaut Mikhail Kornienko, has broken the record for the longest number of days spent in space.
The motive of this mission was simple.
It was to see how the human body holds up for a long time with limited resources.
As we know that SpaceX and Virgin Atlantic are planning space tourism.
As even NASA plans to set up their outpost on the Moon, visit an asteroid, and to colonize Mars, Kelly’s experiment has come out time. We know that more humans will be visiting space soon; hence, this is the best time for Scott Kelly to study something that can prepare us for near future.
Kelly would now undergo extensive medical research.
It’ll be done to find out what effects microgravity has done to his brain, bones and eyes. Past studies show a slight shift towards nearsightedness among astronauts, as it’s a known fact that space squeezes your eyes.
So, how else living in space affects the human body?
If you’re a first timer, be prepared for things like a headache, nausea, vomiting, lethargy, excessive sweating which occurs because of the space adaptation syndrome. The longevity of these headaches and syndrome varies from person to person and can last up to more than two to three days.

According to studies done by NASA…
For long-term, muscle loss is at serious risk. As study shows, without gravity, our muscles become less necessary. In result to this, our bones begin to strip the body of unnecessary tissue. Our body mass declines more than 20 to 40% in this process.
And that’s how they make up for this.
NASA astronauts spend more than 2 hours a day in strength training. If they don’t exercise, then it might be possible that they’d end up losing more than one percent of bone density per month.
Time in space controls your blood pressure.
When you get there, you may not want to take selfies at first, as your face gets puffy and legs skinnier. That’s because fluids start floating upwards in your chest cavity and head.
If you want to sense this feeling, hung yourself upside down for more than 15 minutes, and then ask someone to take pictures. In space, once you settle down in zero gravity, this phenomenon changes back to normal again. Time in space also affects your blood pressure and oxygen intake.

Some of the other main issues are one of these.
Getting exposed to harmful radiation is another worry that is always being faced by many astronauts, because as a result, they get, Cancer.
Astronauts take with them a lot of food to eat during these long voyages. There’s always a chance of these food items getting spoiled over the period. Hence, it causes malnutrition.
Lastly, sleep is the real issue for the astronauts. Flashes of light zip pass the International Space Station time to time, cosmic beams, they’re all perfect to interrupt a deep slumber. Also, the way you sleep in the space with your hands floating all the time is a huge problem. NASA and other space administrations are continuously working to resolve these issues.
