What Really Happens To The Human Body In Space

According to The Atlantic, on July 11, 2021, Richard Branson flew a rocket-powered plane that had been in development for approximately 14 years. We use the word "toward" because it is unclear whether Branson actually reached "space", which is internationally defined as being 62 miles above sea level. Branson reached just over 50, which NASA considers to be equivalent to "space".


Obviously, Branson wasn't the first person to go into space. That was cosmonaut Yuri from the Soviet Union, who, according to history, "orbited Earth at a maximum altitude of 187 miles" on April 12, 1961. According to the Air and Space Museum, American astronaut Alan Shepard became the first American to reach space on May 5, 1961, which was less than a month later.


According to CBS Minnesota, since then, over 500 people have been to space. This includes the businessman Jeff Bezos, who, nine days after Branson's journey, flew 60 miles above sea level (via CNN). According to NASA, the International Space Station, which is 250 miles above sea level, has been visited by 243 individuals.


As we'll see below, deaths in space aren't very common, but that doesn't mean travelling to and from space isn't dangerous. It also does not imply that there will be no effects over time.

The lack of gravity in space does a number on the distribution of the body's fluids



NASA's Human Research Program has developed the acronym "RIDGE" to highlight the five risks that space travel poses to the human body as a result of years of research that is still ongoing. The lack of gravity in space has a negative impact on the distribution of the body's fluids. Radiation, isolation, distance from Earth, absence of gravity (or "microgravity"), and environment (i.e, a closed environment) are all examples of these.


Each of these terms provides a window into the human body in space, despite the fact that none of them tells us exactly what happens to it. Edema (the accumulation of an excess of bodily fluid where it does not belong), particularly in the upper body and face, is something that typically occurs to the human body in space, even when wearing a spacesuit (via Science in the News). According to the BBC, astronauts are specifically known to suffer from "puffy face syndrome". This is classified as "G" gravity. 


According to the USGS, water makes up a significant portion of the human body. Water makes up nearly 80% of babies' bodies; in adults, it's closer to 60–65%. On Earth, fluids are drawn downward toward the lower extremities by gravity, resulting in a roughly uniform distribution throughout the body. Fluids travel upward in space due to the absence of gravity, causing noticeable swelling in the upper body, particularly the face and head


Space travel does a number on the kidneys


In space, the body is tested to disperse natural liquids, the degrees of which are regularly directed, to a limited extent, with help from Earth's gravitational force. According to Science in the News, this gravitational pull moves fluids away from the head and toward the extremities. 


According to the University of Wisconsin Department of Medicine (U W D M), in addition to edema, microgravity can also have a negative impact on kidney health. According to Dr Jonathan Himmelfarb, a kidney specialist, "Certain conditions related to poor kidney health appear more rapidly in space and could have life-long consequences". Protein in the urine, bone loss, and kidney stones are examples of these

What Is Difference Between Chia Seeds And Flaxseed

Image
  Certain seeds have gained a reputation as superfoods in recent years. Examples include the well-known chia and flax seeds. Both have been linked to health benefits such as a healthier heart, lower blood sugar levels, and protection against certain types of cancer. However, many people wonder which of the two seeds is actually the healthiest. Both are extremely rich in nutrients. To answer this question, this article looks at the scientific evidence that supports each The Saliva Hispanic plant, more commonly referred to as the chia plant, is the source of the tiny oval-shaped chia seeds. Chia seeds are slightly larger and flatter than flax seeds. Flax seeds, on the other hand, have a slightly nuttier flavor than chia seeds. However, incorporating both kinds of seeds into a variety of dishes is simple Nutrition comparison Comparative analysis of the nutrients present in chia and flax seeds The major nutrients contained in a 1-ounce (28-gram) serving, or approximately 4 tablespoons,...

Overconsumption of Common Red Food Dye May Lead to Inflammatory Bowel Disease

Image
  Allure Red AC, a synthetic dye found in popular foods like Skittles, Doritos, Gatorade, Jell-O, and Fruit Loops, has been linked to an increased risk of developing inflammatory bowel diseases (I-B D S) such as Crohn's disease and ulcerative colitis if consumed frequently. The dye, also known as FD & C Red 40 and Food Red 17, is thought to have negative effects on gut health and increase inflammation, according to a small study done on laboratory mice. The study, which was recently published in Nature Communications, found that the additive directly breaks the gut barrier, which helps keep bacteria from getting in, and that it also makes more serotonin, a hormone and neurotransmitter in the gut. According to the report, this reaction alters the microbiome of the gut, making people more likely to develop inflammatory bowel conditions. What we have found is striking and alarming, as this common synthetic food dye may be a dietary trigger for I-B D S, said senior author W-A L-I U...

Border violence displaces 76,000 in Lebanon: Hezbollah

 The International Organization for Migration (IOM) of the United Nations reported on Friday that nearly three months of nearly daily fighting along the border with Israel had resulted in the displacement of more than 76,000 people in Lebanon. The boundary region has seen a flood of viciousness since early October, with blow for blow trades of fire forging ahead with Friday between Israeli powers and Hezbollah. In a report distributed on Thursday, the IOM said that the heightening had uprooted 76,018 individuals, predominantly in areas of southern Lebanon lining Israel. More than 80% of the dislodged Lebanese are remaining with family members, as per the report, and just two percent housed in 14 aggregate sanctuaries spread across the south of the country, predominantly in the seaside city of Tire and in the Hasbaya locale. The remainder, according to the UN agency, have relocated to homes or apartments further from the border. Cross-line brutality has left 175 individuals dead in ...
