Astronaut
Space travel is a adventure and risk campaign. Along with this, space travel has a great impact on human body. Space has many times more radiation and microgravity than the earth, due to which it takes a long time to recover astronauts after returning to the earth.
NASA’s Human Research Program has identified 5 threats for astronauts, which astronauts have to face during their visit. These include space radiation, isolation, isolated, distance from the earth, gravity (and its deficiency), and closed environment. These are the dangers that can promote each other and they can have a widespread impact on the human body.
Five risk of space trip
Space radiation
Outside the protective magnetic field and atmosphere of the Earth, ionizing radiation in space will pose a serious threat to astronauts traveling to Mars. High energy galactic cosmic rays, which are the remains of supernova, and solar parties can damage the body and spacecraft such as phenomena and coronal mass ejections. When astronauts travel in space, they cannot see or feel radiation. However, NASA scientists are studying the effects of radiation on the human body and developing this silent danger monitoring and safety methods.
Isolation and isolation
On Earth, we have the facility to pick up our cell phones and connect with almost everything around us and immediately. Astronauts are more isolated and limited than our imagination. Lack of sleep, circadian disinchronization and workload further increase this problem and this affects their functionality and adversely affects health. To remove this danger, experts are developing ways to monitor practical health and refine various tools and techniques for use in space flight environment to detect and treat initial risk factors.
Gravity
A major challenge of astronauts is also about gravity. In space, they are free from gravity. There is a different challenge to be loaded. Astronauts are given complete training to face this challenge. After returning to the earth, they again have to be adapted to gravity. It also has a great effect on the body.
Switching from one gravitational field to another is as difficult. Head-groomed and hand-and-akh affects coordination, balance and actions, as well as some astronauts experience space motion disease. When shifting to gravity from weightlessness, astronauts may also experience dizziness and unconsciousness. Without the constant weight of gravity of the earth, the bones that carry weight lose an average of 1% to 1.5% mineral density per month during space flight. Water and other fluids in the body shift upwards towards the head, which can cause pressure on the eyes and can cause vision problems. If preventive measures are not applied, the crew may increase the risk of developing kidney stones due to dehydration and excess emission of calcium from bones.
Distance from earth
The distance of space from the Earth also affects our body. Staying from this distance for a long time has side effects on the body and the astronaut has to face many problems. Astronauts are given complete training before traveling to how to keep themselves away from the earth.
Off atmosphere
The ecosystem inside the spacecraft plays a major role in the daily life of the astronaut in space. A closed environment like space stations has a lot of side effects on the human body. Stress can increase hormone levels and change the immune system, which may increase sensitivity to allergies or other diseases.
