Before freezing to death, people will have a "paradoxical undressing " phenomenon and even shows a “happy smile”.

A few days ago, a video circulated online showing a man who died outdoors and was found stiff, with his clothes stripped down to his shirt and shorts. It is reported that the man was drunk the night before and passed out outdoors.
Many people think that people who are freezing will wrap their clothes tightly and curl their bodies together so that they can warm up. But in fact, in forensic science there is a professional term called "paradoxical undressing phenomenon", that is, before a person is frozen to death, will take off their clothes, with a smile on their face.

A study done by German forensic scientists analyzed 69 cases of hypothermia and found that a quarter of the patients voluntarily removed their clothing before death.

The reason for this phenomenon is related to the blood vessels at the end of the body.
When people feel cold, the most important thing is to ensure the operation of the brain, internal organs and other major organs, so the blood vessels at the end of the body will automatically contract to ensure sufficient blood flow to the major organs. In this state of stress for a long time, the muscles that constrict the blood vessels will fall into fatigue and can no longer work, and need to take a soothing "break". At this time the peripheral blood vessels on the surface of the body will all open, the blood quickly flow to the end of the limbs, the long-term cold state of the limbs instantly filled with warm blood, resulting in a "very hot" illusion.

However, once the clothes are off, the body temperature drops even more sharply and it doesn't take long to die.
