Why do people get chills when they die How long does it take for a person to get cold after death?

That's because, before death, the functions of various organs are rapidly failing, the heart is not pumping enough, the function of the pulmonary ventilation system is weakened, the energy supply is insufficient, and the heat ** is reduced or even disappears, so it will get colder and colder.

The mind is calm and naturally cool. At that time, the heart was about to stand still.

If you don't have energy, you get cold.

Before death, the amount of blood decreases (such as excessive blood loss), circulatory failure, abnormal respiratory function, etc., which will reduce the heat of the body, and if the dying person is conscious at this time, he will feel "mixed body chills". But these are different from some of the "situations" in movies and TV plots, because they are exaggerated for the needs of the plot.

Brightening methods for plastics:

In addition to the reasonable selection of raw materials, the specific methods include adding brightening methods, blending brightening methods, morphological control brightening methods, molding without finishing control, secondary processing brightening methods and surface coating brightening methods.

1. Selection of plastic raw materials.

The reasonable selection of plastic raw materials is the most basic factor to improve the surface finish of plastic products, and if the raw materials are selected well, it is easy to improve the gloss; On the contrary, it is more difficult.

2. Selection of additives.

Among all the additives used in plastics, fillers have the greatest impact on gloss; Secondly, there are plasticizers, stabilizers and flame retardants, but the impact is small.

In general, the corpse hardens within 30 minutes to 2 hours after death, completely stiffens after 9 to 12 hours, softens after 30 hours, and returns to its original state after 70 hours. However, if it is in soil or water, or in the case of low temperature and dryness, it will be delayed, and it will be accelerated under high temperature and humidity conditions.

Coldness of the face and limbs, corpse spots, and stiffness began to appear, and the elapsed time after death was 1 2 hours. The corpse spots were distributed in patches, and most of the corpse mortis appeared, and the time of death of the corpse was 3 to 4 hours. The corpse spots fused into large patches, the corpse appeared all over the body, the cornea was slightly cloudy, the lips began to wrinkle, and the pupils still reacted with mydriatic and mydriatic drops, and the elapsed time after death was 5 to 6 hours.

Zombies are highly developed, acupressure corpse spots can completely fade, the cornea is highly opaque, and the ocular conjunctiva begins to autolyze about 12 hours after death. The corpse spots can be completely depressed, parchment paper-like spots form, the cornea is highly opabid, scleral dark spots appear, the oral mucosa and ocular conjunctiva are autolyzed, and about 24 hours have elapsed after death.

The timing of the appearance of the above-mentioned corpse phenomena is based on the spring and autumn seasons, which accelerates in summer and slows down in winter.

Putrefactive abdominal distention begins at 8 10 hours after death in spring and autumn, 4 5 hours after death in summer, and 48 72 hours after death in winter. Putrefactive green spots begin to appear about 24 hours after death in spring and autumn, about 12 hours after death in summer, and 72 120 hours after death in winter.

The network of decaying vessels begins to appear in spring and autumn at 48 to 72 hours after death, in summer at 1 2 days after death, and in winter at about 7 days after death. Hair is prone to loss and putrefactive blisters, which appear 3 5 days after death in spring and autumn, 1 2 days after death in summer, and generally do not appear in winter.

The view of the corrupt giants begins to appear in spring and autumn at 3 7 days after death, in summer at 2 3 days after death, and in winter at 15 30 days after death. In the middle of summer, the soft tissues of the corpse liquefy and disappear, and only the bones remain, which takes about a month, and in the case of fly destruction, the time will be shortened. If the corpse is in the water, there are still some corpse phenomena for speculation that the hands and feet are soft and swollen at the time of death, showing a white wrinkled phenomenon, and if it appears in the palms and soles of the feet, the time of death is about 4 hours; If it appears on the back of the hand or foot, the time of death is about 48 hours.

The phenomenon of hands and feet falling off and becoming glove-like, if it appears on the corpse in summer, the time of death is about a week; Winter is around January; In spring and autumn, it is about 2 weeks. The view of the corrupt giant, which appears in the spring and autumn seasons at 7 10 days after death, in the summer at 4 5 days, and in the winter months in the month. It needs to be emphasized again that the occurrence and development of the cadaveric phenomenon is constrained by various conditions.

One: the heart is calm and naturally cool. Two:

Because after a person dies, the metabolism in the body will stop, and the physiological activities of the nerve center will also stop, and finally the body itself will not be able to regulate the body temperature constantly, and the cessation of the heart will stop the blood flow, and the cells of the body that cannot be transported without the corresponding nutrients will also begin to die, and eventually they will become cooler and harder...

Because the heart stops supplying blood, the blood stops flowing, the blood is warm, and if the blood doesn't flow, it gets colder, so the body temperature drops.

When you die, you lose the function of your brain and can't regulate your body temperature through neuroregulation. Body temperature cannot be regulated by fluid regulation

Four words summarize "the heart is calm and naturally cool".

When people are alive, they complete their metabolism by breathing and ingesting food, these foods have energy and produce heat in the body, and when life stops, the metabolism ends, and there is no heat production, of course, it is cold.

When a person dies, the cells in the body also die, and the warmth of the human body depends on the activity of the cells in the body to produce heat.

Because when a person dies, the heartbeat stops, and then the cells and tissues no longer move. The blood does not circulate, so the body is naturally cold after death.

We often say that the human body mainly relies on the flow of hot blood to maintain body temperature, and when the blood is still, the human body will naturally slowly become cooler.

When a person dies, the heart stops beating, causing blood circulation to stop, and the lack of blood circulation causes the body to stiffen.

The body temperature will not be low.

But people who are dying should feel cold.

Those who die will, but those who don't die don't.

I think so.
