Physiology Space

Physiology of space medicine is a branch of medicine that studies the reactions of the human body under space flight conditions. It is aimed at developing methods and means to protect humans from the adverse effects of space flight factors, such as weightlessness, physical inactivity, radiation and others.

During space flights, astronauts experience many changes in their bodies. One of the most important factors is weightlessness. In the absence of gravity, blood begins to accumulate in the upper part of the body, which can lead to poor circulation and poor heart function. Additionally, the lack of gravity can cause disorientation and dizziness in astronauts.

Physical inactivity is another factor that can negatively affect the human body in space. With prolonged exposure to weightlessness, muscles begin to atrophy, which leads to a decrease in strength and endurance. In addition, physical inactivity can cause disturbances in the functioning of the cardiovascular system and other organs.

Radiation is another important factor that must be taken into account when developing methods to protect astronauts from cosmic radiation. Radiation can cause various diseases such as cancer, radiation sickness and others. Therefore, it is necessary to develop special means of protection against radiation.

In addition, in space conditions, astronauts may encounter other factors, such as pressure changes, temperature changes, etc. All these factors can negatively affect the health of astronauts, so it is necessary to develop methods and means to protect people from the adverse effects of these factors.

Thus, the physiology of space medicine plays an important role in the development of methods and means of protecting astronauts from the adverse factors of space flight. It allows scientists and engineers to better understand how the human body responds to different space conditions and develop new methods and technologies to protect astronauts on future space missions.

Space flight physiology is a branch of physiology and space medicine. She studies the reactions of the astronaut’s body to the effects of space flight factors (weightlessness, physical inactivity, and others) under flight conditions. The goal of cosmophysics is to develop methods and means to protect human life in space. Research in the field of space physiology is closely related to the achievements of science on the functional systems of living organisms. The task of space science is to study the structures and physiological processes that underlie specific human life support systems and provide the ability to maintain his life in extreme conditions of space. The difficulties that space physiology has to solve are varied. In addition to the difficulty of creating space flight models, the peculiarities of outer space also make it difficult to conduct experiments. Namely, the need for constant comparison of research results with extensive human medical practice. The complexity of space physiology lies in the fact that a person has to be in unusual conditions of weightlessness; all this can't help but

As in all areas of science, physical processes and laws take place in space flight. One of the main tasks that must be solved when preparing for space flights is preserving the health and life of people on board spacecraft. Therefore, space flight physiology is one of the most important areas of research.

Space flight physiology studies the reactions of the human and animal body to the effects of space conditions, such as weightlessness, microgravity, radiation, cosmic rays and other factors that can affect the health of cosmonauts and astronauts. The purpose of this section is to develop methods and technologies that will reduce the risk of complications and protect astronauts from the negative influence of all these factors.

The first most important factor in outer space is the lack of gravity. If the human body develops in conditions of Earth's gravity, then changes in gravity can lead to serious physiological consequences. In zero gravity, the brain can begin to leak because blood stops flowing to the head. The normal flow of blood is also altered: it pools in the veins due to the lack of gravity and can cause venous congestion. In addition, in the absence of gravity, blood begins to accumulate in the organs - this can lead to various diseases. Under such conditions, it is difficult to determine normal body temperature. Infrared sensors that are used to measure temperature on Earth cannot measure temperature in zero gravity. All processes occurring in the body in the absence of gravity or at high altitudes are called microgravity medicine.
