What do you think people see when they are dying?

“Vista Seeing the World” once interviewed 4 people who passed by death, and today we are going to talk about one of them – 42-year-old An Ning, < /span>A Cambridge scholar who was declared dead two hours after being declared dead by doctors.

12-year-old An Ning went home with her classmates after school, but a bus suddenly came around the corner. An Ning was knocked over and collapsed on the snow. Fortunately, a passing teacher saw him and took him to the hospital.

He was treated in the hospital for three days, from being awake, to a coma, to losing his breath, before doctors pronounced him dead. The grieving parents could not accept his death and continued to cry for 2 hours until he seemed to be breathing again, and doctors rescued him again.

After waking up, An Ning said, at that moment he was like a fish wandering in the dark, swimming from the dark to the white microbes. Light, then woke up with a distant call.

This experience sounds very unscientific and metaphysical. Is there any scientific basis for the claim of “near-death experience”?

1. Is “Near-Death Experience” real?

Breakthroughs in medical technology have opened up the small shackles in human life to a certain extent, and many patients who are on the verge of death can also have the opportunity to be rescued, thus leaving behind the experience of near-death experience. describe.

According to medical surveys, the incidence of near-death experience is about 17% in prospective studies in 4 countries.However, Only 1 in 10 retain memories.

In 1975, a book by Raymond Moody, M.D., titled “The World After Death”, drew attention to the afterlife. The world, and the term “near-death experience” coined in the book, summarizes past people’s near-death experiences.

Subsequent scientists have carried out research on this, and believe that near-death experience refers to the fact that the human body is infinitely close to death, even after medically determined death, one’s own senses are not restricted, A special experience of being able to reminisce about the past, seeing relatives and friends, and finally returning in the light of peace and love.

Are near-death experiences real or are people fictional?

• In 2001, a Dutch study published in The Lancet found that 62 of 344 cardiac resuscitation patients had near-death experiences. The incidence rate was 18%;
• In 2014, a US-UK joint study interviewed 101 patients out of 2,060 cardiac arrest patients in 15 hospitals,
• span>55 of them retained partial memories of near-death experiences, and the other 46 had no relevant memories;

In March of this year, in the journal Frontiers in Aging Neuroscience, scientists at the University of Tartu, Estonia accidentally recorded the life activity of the brain while treating an 87-year-old man who suffered a head injury from a fall. , found that within 900 seconds before and after the patient’s death, from the onset to the cardiac arrest, the activity of gamma waves in the brain waves was abnormally active .

And gamma waves are closely related to brain attention, memory, dreams, information, consciousness, etc. The results of this study It seems to corroborate with many near-death experiences.

But in fact, up to now, there is no particularly good explanation for the phenomenon of near-death experience. There are many speculations in the scientific community, but none of them have been confirmed… The truth of the matter Still to explore

Second, what is the process of different ways of dying?

Although the cause and mechanism of NDEs are still unclear in the medical community, its existence is beyond doubt. But in life, there are always too many accidents, and death comes in a variety of strange ways.

The human body may be burnt to death, drowned, held to death… What is the difference between the death experience brought by so many ways of death?

People generally go through three stages before dying, namely moribund stage, clinical death stage, and biological death stage. In the first two stages, the patient still has the possibility of treatment and reversal; and in the biological death stage, it means that the human brain has been irreversibly damaged and cannot be recovered.

And the experience will be different between different ways of dying:

1. Burn to death

When the human body is burned, the harmful gases and The heat will damage the respiratory tract and cause hypoxia to suffocate and die.After being lucky enough to escape this disaster, it is even more uncomfortable.

If hair and clothing are accidentally ignited, the fat in the body will continue to burn like lamp oil, and finally be burned alive.

2. Drowning

Human drowning, often in an environment with a large amount of water , at this time, it is difficult to make a sound even if it is fluttering hard, but it will fall off faster because of the force.

Choke on water after falling into the water, which will cause water to flow into the lungs, causing pain and damage to the lungs, and also causing ear damage when pouring into the ears. On average 5 minutes, the human body will die due to lack of oxygen.

3, starvation

The human body has no exogenous nutritional supplements, and will “eat itself” when it lacks nutrients. The whole process is: glycogen-fat-muscle (protein), when the protein is digested, the water If it cannot enter the blood and be excreted, it will accumulate in the body and cause edema, so some people who starve to death will “get fat” instead.

4. Dying of thirst

When the human body is dehydrated, the body locks in the remaining water in order to It will stop sweating, causing the internal organs to overheat, which may lead to failure. When the water shortage is severe, the brain shrinks, and functional disorders and mental madness may occur, and eventually die due to the rupture of cerebral blood vessels.

5. Cut the wrist

If the wrist cut is not subjected to “special treatment”, it is generally It cannot die, because the human body has its own coagulation function. Generally, the damaged vein will repair itself, but it will leave scars. If the nerve or tendon is accidentally damaged, it may lead to disability.

6. Swallowing sleeping pills

A large number of sleeping pills enter the human body, which will increase the burden on the stomach and intestines. It causes vomiting and nausea, reflux of gastric juice from the mouth and nose, and burning of the mucous membranes, which is very uncomfortable. Severely affects the nervous system, leading to neurological confusion, possibly maddening, twitching of the hands and feet.

In addition, there are other ways to die, all of which can cause serious damage to the body and bring unbearable pain. We must pay attention to protection in life. yourself, out of danger.

3. How much do you know about these “secrets” of dying?

Faced with death, people are always afraid. When many people experience the death of the elderly, they will find that the human body often has some unusual behaviors before death, and these secrets may be revealed by people. The first step of the veil.

• Why do people cry before they die

The human body Before death, organs and tissues will gradually fail, and the lacrimal gland will also stop and close. At this time, the sphere will flatten, and under the stimulation of bad emotions, excess tears will be discharged< /span>, a phenomenon that leads to tears before death.

• The spirit suddenly improves, is it “return to the light”?

< span>The mechanism of the occurrence of the return of light is still unclear. The medical community currently believes that it may be the brain nervous system during the dying period, which controls the adrenal gland to secrete various hormones through the hypothalamus, which stimulates the human body.

may also be associated with energy bursts caused by adenosine triphosphate (ATP), which affect human organs Or the tissue causes a short period of stimulation or enhancement that triggers the flashback.

• What happens when a person sighs after death

After a person dies, the bacteria in the body will multiply, and the bacteria will produce dirty green and putrid gases. These gases are locked in the body. When the airway of the corpse is opened by the outside world, the gas will be discharged along the airway, which will produce a sound similar to a sigh.

A small number of corpses that hang themselves are removed and laid flat, and the airway is opened.

A person’s life is an alternation of rebirth and death. Many people are very afraid of death. As everyone knows, this is also a part of life. It is good to face it calmly. Perhaps if you face this process squarely, you will be able to discover more mysteries of the human body and play a role in promoting the progress of medicine. At the same time, it also reminds everyone to stay away from danger in life and care for life.
