Why do astronauts seem to agree extremely extremely?

As is known, Williams and although after their arrival at the international space station ISS they had to spend only a week in the room in June of the previous year.

Due to technical problems with the spaceship “Starliner”, NASA decided for security reasons to have the spaceship developed by the American group to fall back to Earth. Eventually the two astronauts had to tolerate for about nine months at the ISS together with Aleksandr Gorbunov and Nick Hague.

Astronauts weakened and tired
The space tires were over on Wednesday morning, all occupants of the “Dragon” room capsule have landed safely. The effort of the journey and effort in space could be seen. They seemed physically weak, excited and tired.

For years older?
Just like Barry Whilmore, Suni Williams (59) spent 288 days in the room. Your body was not exposed to gravity for almost nine months. This influences natural body and brain.

In particular, William’s years old – and it is also organic.

Stress leaves her gray
A 2020 study showed that stress can favor the gray of the hair, because stress hormones such as adrenaline and cortisol accelerate the breakdown of melanin -forming stem cells in the hair follicles.

Moreover, astronauts only have a very limited access to water, so that they wash their hair in water bags from foil and plastic with shampoos without rinsing.

Vitamin D deficiency makes astronauts “pale” look
Due to the lack of sunlight, the skin often pale with many astronauts. The bones also miss the important vitamin D, which astronauts can only deliver based on preparations. The epidermis becomes thinner in the room.

Wounds take longer to heal because the ability of the skin to regenerate is limited. The immune system is also permanently weakened by external factors.

Insomnia big problem
We sleep in a sleeping bag that is attached to the wall. Sleeping mask and earplugs are a must, the last, to be able to hide the sound of fans, pumps and machine groats. Nevertheless, many astronauts suffer from insomnia. This is dangerous because inattention and concentration difficulties can have fatal consequences!

NASA recommends 2.5 hours of sport in space
Moreover, they quickly lose muscle mass because they do not use their legs, the spine, etc. in weightlessness. This increases the risk that bones will become bros. According to NASA, astronauts are supposed to practice at least 2.5 hours a day to prevent muscle and bone loss and to maintain the physical power that is quickly reduced and longer.

Cardiac arrhythmia often
Another danger: the stay in space also weakens the heart because it does not have to pump the blood against gravity and therefore does not work that much. The blood volume also decreases. Venous thrombosis and “chicken legs” (these losses in the legs also seem thinner, nut) are common.

Many astronauts also lose weight in space. They miss the appetite, they suffer from nausea or do not get any taste for Tütens soups and stews.

Astronauts lose a lot of body liquid
A longer stay in the room also damages optical nerves and influences the smell. There are no showers on board the ISS, water is considered precious. As is known, astronauts drink from a water preparation system recycled. Dehydration is a problem because astronauts lose a lot of body liquid.

Radiation dangerous
Perhaps the most dangerous effect of a longer stay in space is the exposure to radiation, which can increase the risk of developing diseases such as different types of cancer and Alzheimer’s. An astronaut who is on the road for six months or more is exposed to more than ten times as much radiation as on earth.

How do you continue after a successful landing for the astronauts? Williams and Wilmore have already completed their first medical examinations and, as soon as they have become used to gravity, complete a 45-day rehabilitation program, in which they train seven hours a day seven days a week.
