Why do some bodies scream or sit up when cremated?

Some people may have seen such a strange phenomenon in the crematorium, that isA person who is clearly deceased suddenly stands up when he is burned, or makes some strange noise, as if screaming. For these phenomena, some people will think that people are not dead, so what is the truth?

Why do some bodies sit up or scream when cremated?

Cremation takes place on the premise that the person being cremated has died, otherwise cremation would not have been possible. When burning, that kind of pain is rarely able to resist, if a normal living person is burned, he will let out an irrepressible roar of pain, becausePain in nerve conduction is too severe.

In the field of forensics,If a person is burned to death in a living state, then he is not the same as the cremation state after death。Living people have very painful expressions on their faces, their limbs curled up, and more soot in their nasal cavities, which travels all the way through the trachea to the lungs. And after death, incineration, regardless of whether the body moves or not, it is impossible to struggle violently and for a long time as if it were alive, and the nasal cavity will be cleaner.

At the time of incineration, due toGenerally, cremation is carried out within two or three days of deathThere may be a certain amount of oxygen in the lungs, and the water content in the cells and tissues of the whole body is relatively high, and some tissues may still have some activity. So when the tissue shrinks on its own when burned, it makes the body appear to be moving, but this is only temporary.

At the same time, due toThe temperature in the incinerator is too high, according toThe principle of thermal expansion and cold contractionIf the lungs of the body are fragile, then the gas may seep out of the gaps in the tissues, which will cause some movement, as if the body is screaming. WhileThe sound caused by the gas in the lungs is not like the sound that our throat normally makes, but more like the sound of air flowing through a relatively small gap, and sometimes even faintlySound

It is impossible for a crematorium to cremate a large living person, unless there are special circumstances. So, no matter what happens to the body, we don't need to pay attention to it, just continue with the incineration process.

This is because the temperature is particularly high in the process of cremation, and it is also because of the thermal expansion and contraction, so some of the gases in it will expand, and it is easy to make some sounds.

Because some bodies will undergo some special physical changes when they are cremated, they will scream or sit up during cremation.

Because the muscles are in a state of contracture when the body is burned, the body suddenly sits up, and these are the muscle reactions.

Cremation is cruel, and the process of cremation of human remains is too terrifying, and it will leave a serious psychological shadow after seeing it.

The body was transported into the combustion chamber by the staff, and the body could not be cremated immediately. That is, the body needs to be cut first, including the main trunk cavity of the human body, and the internal organs of the body will flow out. If it is not cut first, then the body is likely to have an accident due to uneven heat, and after the treatment, the body will be sent to the furnace, sprayed with diesel gasoline, ignited and began to burn.

Flammable parts of the body, such as hair, are quickly burned. The skin will squeak and burn. The muscles and internal organs of the whole body will gradually turn into fire balls.

In no time, the eyes will explode, revealing black eye holes on the head. When the muscle tissue is almost burned, the bones will slowly appear. The staff smashed some of the lumpy bones, burned them again, and then selected some of them to be placed in the urn.

Precautions and key points for cremation:

After the body is sent to the cremation workshop, go through the formalities for cremation, and the name of the columbarium must be consistent with the body and the furnace number; Boiler workers to relatives to sign after announcing the cremation of the remains began; Relatives can observe the cremation process of the body in the examination hall outside the furnace or in the computer-monitored isolation room; After the cremation of the body, the ashes are presented, and the boiler worker will transfer the ashes to the funeral home management or relatives to collect them.

That's because during cremation, when encountering high temperatures, muscles and tendons contract.

Even the muscle tissue is able to feel the burning pain, so it reacts. That's why I sat up in the crematorium. If the time of death is separated by cremation for a long time, the tissues and cells and neural networks in the human body will not react if they die completely.

During cremation, the human body is subjected to high temperatures, and after being subjected to high temperatures, the human muscles will tighten and dehydrate, after which the person will arch slightly, as if sitting up.

This is not the cry of man.

We know that when people speak or scream, it is the sound of the vocal cords vibrating because the air in the lungs moves in and out to push the airflow to drive the vocal cords.

When people are cremated, the body is made of a certain amount of air (especially in the lungs), and when the fire is heated, the air in the body will expand rapidly due to the principle of cold contraction of heat and viscera, and it will be eliminated from the body through the mouth.

I haven't seen it either, it's purely analytical.
