 How Do Astronauts Live In Space ?

Author : TANISSHKA A MISHRA

Hi guys , today I will tell you how do astronauts live in space

Living in space is not the same as living on Earth. In space, astronauts' bodies change. On Earth, our lower body and legs carry our weight. This helps keep our bones and muscles strong. In space, astronauts float. They do not use their legs much. Their lower backs begin to lose strength. Their leg muscles do too. The bones begin to get weak and thin. This is very bad for astronauts' bodies. So, how do astronauts help their muscles and bones? They must exercise in space every day.
The heart and blood change in space, too. When we stand up on Earth, blood goes to our legs. The heart has to work extra hard against gravity to move the blood all around the body. In space, without the pull of gravity, the blood moves to the upper body and head. Water in the body also does the same thing. It makes the astronauts' faces look puffy. The blood and water are fluids in the body. These fluids move from the bottom of the body to the top. The brain thinks that there are too many fluids. It will tell the body to make less. When the astronauts come back to Earth, they do not have enough fluids in their systems. It takes their bodies a few days to make more blood and water. The astronauts have to rest so their bodies have time to make new blood and water. If they don't, they can feel very weak. They might even faint!

This is how they live
Now let me tell you how do they stay clean
On Earth, people need to stay clean. In space, astronauts need to stay clean, too. Staying clean takes more work in space. In space, the astronauts do not have a bathroom as we have at home. But, they do have their own toothbrushes, toothpaste, combs, brushes, and shavers. These are kept in a Personal Hygiene Kit.

Astronauts use toothpaste and toothbrushes just like yours. There is no sink like yours on the Space Shuttle, though. Astronauts have to spit into a washcloth.

People take baths a different way in space, too. Astronauts use special kinds of soap and shampoo. These soaps do not need water to rinse. Astronauts must use them carefully. They do not let the soap bubbles go all over the place. After washing, they use a towel to dry off. They do not rinse. These special soaps and shampoos were made for hospitals. Patients who cannot get in the water use these soaps.

Those Were The Days ... Author : SHRIYANS CHANDAN MOHAPATRA

  Those Were The Days ... Author : SHRIYANS CHANDAN MOHAPATRA Do you wish you could return to moments from your past? Yes, I wish I could return memories from your past as those were the days. Many people say that growing up is the best part of life. But I disagree. Growing up means a smaller margin for errors, a necessity for seriousness and I just dislike all of those. The only positive about growing up Is total freedom. No one to stop from chasing your dreams except you yourself. But then you need to mature and grow responsible, along with still obeying everyone; that is an expectation that others have of you. Meanwhile when you are a child; a chick whose egg has just cracked, your mistakes are turned into a laughingstock and your naughtiness are converted into a chance to snuggle into your mother’s safe hands. I tell you those were the days. I sometimes feel as if I would give everything I have, even if it means my life to go back in time. Sometimes I feel if only everyone...
