At all times, people were interested in: why does a person die? In fact, this is quite an interesting question, for the answer to which we can consider several theories that can shed light on this situation. There are many different opinions on this topic, but in order to understand what death is and why a person is subject to it, it is necessary to solve the mystery of old age. At the moment, a large number of scientists are struggling to unravel this problem, completely different theories are being put forward, each of which, one way or another, has the right to life. But, unfortunately, none of these theories have been proven at the moment, and this is unlikely to happen in the near future.
Theories related to aging
As for opinions on the question "Why does a person die?", then they are all as diverse as they are similar. What these theories have in common is that natural death always comes with old age. A certain circle of scientists is of the opinion that old age as such begins at the moment of the emergence of life. In other words, as soon asa person is born, an invisible clock starts its reverse movement, and when the dial is reset to zero, the person’s stay in this world will also stop.
There is an opinion that until a person has reached maturity, all processes in the body proceed in an active stage, and after this moment they begin to fade away, along with this, the number of active cells decreases, which is why the aging process occurs.
As for immunologists and part of gerontologists who tried to find an answer to the question “Why does a person die?”, From their point of view, with age, autoimmune phenomena intensify in a person against the background of a decrease in cell response, which, in essence, leads to the fact that the body's immune system begins to "attack" its own cells.
Geneticists, of course, say that the whole problem lies in the genes, while doctors say that human death is inevitable due to body defects that accumulate throughout life in a person.
Law of nature
But still, why do people grow old and die? Could it be that this is how human nature was designed to ensure a perfect balance on the planet? After all, if people never died, then after a short time they would flood the entire planet, thereby leading it to irreversible death. But at the same time, you should first pay attention to the fact that the aging of the body did not begin with people, but with unicellular ciliates. The problem is that it is almost impossible to create perfect DNA, despite the fact that a person is already able to edit his program. Thus, it is possiblesummarize and give a more or less adequate answer to the question of why a person dies. This is due to the fact that human DNA is not able to constantly maintain the balance of the body without experiencing any losses. In order to maintain this balance and prevent the occurrence of cancer, the body's vital processes begin to slow down, which leads to aging and, as a result, death.
Sudden death
Based on international guidelines, sudden death occurring within 6 hours of first symptoms is often due to cardiac arrest or any other cause that cannot be determined. In other words, for doctors, sudden death means death without any known cause. For example, if a person was hit by a car and his death was instantaneous, then this does not mean at all that there was a sudden death, since it was caused by injuries incompatible with life. We figured out the definition, now let's move on to the symptoms that can serve as a prerequisite for a sudden death.
Sudden death symptoms
Among the signs that can tell 100 percent about future problems is the lack of circulation. But in order to diagnose this, you need to have elementary skills. When measuring the pulse, it must be understood that this should never be done on the radial artery. Measure the pulse on the external carotid arteries, the best way to do this is to measure the pulsation in the neck. It's doneas follows: the number of beats that are counted in 15 seconds must be multiplied by four - and you get the number of beats / min.
Convulsions and lack of consciousness are the second signs that may indicate a state of clinical death or obvious disturbances in the functioning of the human body. At the same time, convulsions can be quite difficult to determine, since they are often very fleeting, and with the turmoil that is created in a stressful situation, it happens that no one pays attention to them, and in vain.
The presence or absence of adequate breathing can also indicate problems. Adequate breathing refers to approximately 16–22 breaths per 60 seconds. You can also look at the reaction of the pupils to light, but this symptom cannot be assessed as reliable, since the pupils may respond inadequately depending on certain drugs or even due to the use of narcotic drugs.
Causes of sudden death
Sudden death (the causes of which can be varied) is mostly due to ischemic heart disease, the onset of ventricular fibrillation or, less commonly, cardiac asystole. But, despite the fact that, according to statistics, about 90% of all deaths are caused by heart problems, there is still a fairly large number of problems due to which this can happen. Despite this, sudden death, the causes of which were mentioned above, actually threatens only a small percentage of humanity, and those who lead a he althy lifestyle do not fall into the group at all.risk.
Where can sudden death surprise you?
As practice shows, it can catch a person absolutely anywhere in the world and at any moment. But the problem is not where sudden death can occur, but that the correct diagnosis cannot always and everywhere be determined. It should be understood that there can be no sudden death in a person who was being treated in a hospital and suddenly fell dead: it is quite obvious that clinical studies and analyzes were carried out, on the basis of which an anamnesis was recorded, etc. Thus, it is put exclusively clinical diagnosis. The same is true if a person has died as a result of a protracted illness.
Top causes of death
Referring to statistics, heart disease is considered the main cause of all deaths worldwide. As for the second most common cause of death, it is worth noting such a terrible disease as cancer. In countries such as China, people are more susceptible to liver cancer, while lung cancer is more common in Switzerland, Spain, Austria, Portugal, the Netherlands and Denmark. The third leading cause of death on the list is AIDS (HIV). This "popularity" is due to Africa, while in the US and Europe they were able to more or less cope with this problem. By the way, with regard to Africa, the problem of tuberculosis is also relevant in this country. The causes of death precisely because of this disease are due to the fact that the country has a very low level of hygiene, and vaccination is notwidespread so that all segments of the population can feel safe.
Among all the countries in the world, Mexico deserves special mention. This is the only country where the main cause of death is cirrhosis of the liver. This is due to the fact that the people of Mexico consume alcohol in relatively large quantities, and also because of the large-scale spread of hepatitis C.
Finishing this list are less common diseases that are “relevant” mainly in Asia and Africa. The causes of death in these countries are mainly kidney disease and respiratory disease.
Death in a dream
Many believe that the best death is the one that comes while you are sleeping. Maybe this is the best option for leaving life, but no one can confirm this. But as for death in a dream, this is a fairly common fact, especially among older people. Q: Why do people die in their sleep?
Thanks to scientists from the USA who conducted research on this issue, it became known that people die while they are in the "kingdom of Morpheus", mainly due to respiratory arrest. This happens mainly in older people due to the loss of cells that control the breathing process, sending signals to the body to produce lung contractions. In principle, this problem can occur in a lot of people, its name is obstructive sleep apnea, and this problem is the main cause of snoring. But such a cause of death as obstructive sleep apnea cannot be. itdue to the fact that a person experiencing oxygen starvation (insufficiency) wakes up. And the cause of death is central sleep apnea. It should be noted that a person can even wake up, but still die due to a lack of oxygen, which will be the result of a stroke or cardiac arrest. But, as mentioned earlier, this disease affects mainly older people. But there are those who die before they reach old age. So a reasonable question arises: why do people die young?
Death of the Young
It's worth starting with the fact that in recent years, approximately 16 million girls in the age group from 15 to 19 years old become childbirth. At the same time, the risks of infant death are much higher than those of girls who crossed the 19-year barrier. These problems are caused by both physiological and psychological factors.
Not the least of which is malnutrition, with both obesity and anorexia problems.
Smoking. Drugs. Alcohol
As for bad habits, such as the abuse of alcohol, nicotine, and even more so drugs, this problem affects more and more young segments of the population every year, who not only put their future children at risk, but also themselves.
Unintentional injuries are still the most common cause of death among the young population. Causeit can also be alcohol and drugs, not counting the youthful maximalism that cannot be discounted. Therefore, until the moment when teenagers have reached the age of majority, the entire responsibility for moral and psychological education lies entirely with the parents.
How does a person feel at the moment of death?
In fact, the question of how a person feels after death has worried all of humanity throughout its existence, but only recently it has begun to be said with certainty that all people at the time of death experience definitely the same feelings. This became known thanks to people who survived clinical death. Most of them claimed that even lying on the operating table, being in an immobilized state, they continued to hear, and sometimes even see everything that was happening around. This is possible due to the fact that the brain dies in the very last turn, and this happens mainly due to lack of oxygen. Of course, there are also stories about the tunnel, at the end of which there is a bright light, but this particular information is actually not reliable.
In conclusion
Deepening into the problem and understanding it, we can confidently answer the question: why does a person die? Quite often people ask themselves such questions, but you should not devote your whole life to the problem of death, because it is so short that there is no time to spend it on learning about those problems for which humanity is not yet ready.
