Why do dead people suddenly sit up when they are cremated?

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.

To put it simply, it is an indisputable fact that burial is a known ** of certain environmental pollutants.

The areas where cremation and burial are permitted shall be demarcated by the people of provinces, autonomous regions, and municipalities directly under the Central Government, and shall be reported to the civil affairs department for the record by the people's civil affairs department at the same level.

The remains of the above-mentioned 10 ethnic minority patients who have died of other infectious diseases are allowed to be buried in the place where they are registered, but the remains must be strictly disinfected in accordance with regulations and buried deeply; The remains of patients who have died in the place where their household registration is not located shall, in principle, be buried on the spot and in the nearest place as soon as possible after strict disinfection in accordance with relevant regulations, and the remains must not be transported to other places. Where cremation is voluntarily requested, others must not interfere.

The state in most areas (except for remote mountainous areas and those who do not have cremation conditions) to introduce the cremation system, the purpose is to reduce the traditional burial of the occupation of cultivated land, at the same time, the coffin for burial is in the forest, in China's per capita arable land and forest coverage rate is less than half of the world average, the population base is very large, even if one person occupies one square meter, the current situation of 1.3 billion people can be imagined.

In addition, the cost factor often makes cremation more attractive. In general, cremation costs less than traditional burial services, especially if direct cremation is chosen, as long as the body is cremated as soon as possible according to the law, without any other form of service.

However, the cost of cremation services can vary greatly, mainly depending on how the deceased or their family wishes the cremation ceremony to take place. Cremation can be performed in traditional funeral services, which increases the cost. The use of the coffin also affects the cost.

Cremation can be said to have a long history in China, but for a long period of time, cremation is only a national and regional funeral custom. With the widespread spread and influence of Buddhism and the development of social economy, cremation was also popular for a time in a specific period. However, at that time, cremation was mainly practiced in the incarnation caves of some temples, which was a religious act, which was completely different from the modern meaning of cremation.

The earliest crematoriums appeared in the concessions of the late Qing Dynasty, and strictly speaking, crematoriums were imported and influenced by Western countries.

After the victory of the Anti-Japanese War, some large cities began to discuss the urgency of cremation. This is mainly due to the high number of deaths during the war, and the traditional way of transporting the body back to the countryside for burial has caused a backlog of coffins in the city.

A large number of bodies could not be transported out in time, and they rotted and smelled in the city, causing serious traffic problems and health and safety hazards. Some large cities began to carry out centralized cremation and burial of long-standing remains, and crematoriums and public cemeteries began to appear in large numbers.
