Eight years ago, in the early morning of a winter, a female corpse was found in the bushes next to Route 17 in New Jersey, USA. Strangely, not far from the corpse, pieces of clothing and an empty wine bottle were found, and the frozen corpse was in a half-hidden state, which was accurately frozen in the process of getting dressed.
Local police came to the scene and initially speculated that the woman may have met a drunk man and wanted something indescribable to happen. After the incident, the lady used her last strength to find and put back some of her clothes before freezing, and finally froze to death in the grass.
As the investigation progressed, prosecutor John discovered that there was no second person at the scene at the time of the incident. The deceased, named Kristin Bezak, had fingerprints on the bottle and learned from her husband that Bezac had a history of alcoholism.
Bezac's husband and loved ones asked: Why would Bezac keep himself unsheathed and then put on on a night when the temperature was close to zero? Just because you're drunk? The county medical examiner gave an explanation: the phenomenon of temperature loss.
<h1 class="pgc-h-arrow-right" data-track="5" > temperature loss</h1>
"The Little Girl Who Sold Matches" is actually a story about the loss of temperature. On Christmas Eve, the hungry little girl did not sell a single match, and finally she polished the matches, and as the matches were lit, she saw the warm fireplace, the roast goose, the Christmas tree, the grandmother, and finally died with a smile on the corner of her mouth.
Although this is a story, in real life, people who freeze to death leave with a smile, and they can feel warmth and happiness like a little girl before freezing to death, which is real. In addition, 20% to 50% of people who freeze to death will experience the phenomenon described in medicine [abnormal undressing], and all this stems from the loss of temperature.
<h1 class="pgc-h-arrow-right" data-track="8" > what is out-of-temperature</h1>
Hypothermia, simply put, is hypothermia. Humans are mammals, and constant body temperature is the main feature of mammals. In the case of not being hungry and keeping warm enough, the constant temperature regulation mechanism in the body will be through energy metabolism, so that the body will remain at about 36.5–37.5 ° C, even if it enters the high-temperature sauna, the body will also maintain this temperature through heat dissipation mechanisms such as sweating.
However, when the ambient temperature changes rapidly and the warmth is not sufficient, it is easy to appear that the [heat radiated outward by the body] is greater than the heat generated by the regulation mechanism in the body, which means that the overall heat is constantly decreasing, and the body temperature will drop.
When the body temperature is below 35 degrees
The body will tremble involuntarily, breathing will become short, and the brain will be in a state of excitement, because the brain needs to prompt you to perform self-slapping, rubbing hands, stomping feet and other behaviors, physically heating up from the outside.
When the body temperature is below 32 degrees
The body will no longer tremble, breathing will become slower than normal, and the metabolism will decrease. Lacking a supply of oxygen, consciousness has begun to blur, like drunken "fragments", slurred speech, and slow movements (such as walking in a straight line, writing). The body gradually loses its sense of pain, at this time who gives you a beer bottle on your head, you basically have no feeling, and the whole person falls into a groggy state.
When the body temperature is below 28 degrees
You're basically unconscious, but the brain is fighting your last life by starting the strategy of abandoning the car.
Because the surface of the skin is closer to the outside, the temperature is lower, the blood vessels will begin to contract, resulting in blood flow mainly concentrated in important organs and the main parts that maintain vital signs, and some surface parts such as the ends of the limbs will have irreversible frostbite, or even frostbite. At the same time, the body's thermoreceptors will fail, causing people to appear "without a wisp" and laugh.
When the body temperature drops below 20 degrees, the heart will stop beating and vital signs will disappear.
<h1 class="pgc-h-arrow-right" Data-track="19" Why do > laugh and spontaneously shed their clothes? </h1>
Many of the deaths due to temperature loss are due to the loss of clothing. Because the loss of clothing will accelerate the loss of heat and accelerate the decrease in body temperature.
The mainstream explanation for this phenomenon is that hypothermia leads to the failure of thermoreceptors, causing the hypothalamus in the brain, which is responsible for regulating body temperature, to make a wrong judgment and thus perform reverse operations.
Put simply: the body is cold, but the brain makes you feel hallucinatory heat, like a little girl seeing a fireplace. The unbearable heat can make people unconscious, leaving themselves naked.
At the same time, the hypothalamus (anterior region) also controls the muscles of the human face through nerves, because it is out of control, so the hypothalamus will make people show a mysterious smile before dying.
In addition, in the final stage of the human body's detemperature, it will also stimulate the original protective mechanism hidden in the human body, similar to hibernation. At this time, people will spontaneously look for small spaces, just like cavemen hiding in caves, escaping the cold, reducing the loss of heat, which is called the "ultimate burrowing" model in biology.

As the old saying goes: warm up with a glass of wine, this is actually an illusion. Alcohol does make blood vessels relax, let the blood flow to the epidermis faster, make you feel warm, but a large amount of blood accelerates to the surface, which also means that the body's heat is lost faster. At the same time, alcohol makes the brain temperature control system unable to accurately distinguish body temperature, and it is impossible to open the metabolic thermogenesis, tremor and other heat-raising mechanisms in time.
Simply put, a drunken body walking on the snow will give up all cold resistance mechanisms, while accelerating heat loss, so that the body quickly enters a detemperature state. This is why there are often drunken men in the northeast winter, and it is also the cause of Bezak's drunken death.
