In some cases, people who die from cold in extreme temperatures can live again. A researcher managed to explain this phenomenon by experiments performed with yeast and worm.
Freeze to death or 'freezes to death' is triggered by cold temperatures that are too extreme, which often occurs in the mountains or cold climates. Although very rarely, someone who could freeze to death back to life.
The first case occurred in the winter of 2001, happened to Erika, a baby 13 months in Canada. Because wearing only a diaper when roaming outside the home, he died with the body temperature dropped to 16 degrees centigrade.
When found, it is estimated the baby's heart had stopped beating for two hours. Miraculously, the baby's heart beating again shortly after warmed and given artificial breathing.
The next case occurred in Japan in 2006. A man, Mitsutaka Uchikoshi Rokkō lost in a snowy mountain and found 23 days later in a frozen condition and shows no signs of metabolism.
The man was finally brought to life again after a warmer place, and be helped. Even his health condition was reported recovered shortly afterwards.
Preceded by no oxygen conditions
Scientists from the Fred Hutchinson Cancer Research Center, Mark B. Roth, Ph.D. trying to explain this phenomenon through an experiment. As quoted from Science Daily, Friday (06/11/2010), Roth uses yeast and earthworm embryo (nematodes).
In the first experiment, he put the yeast and the embryos are at a temperature above freezing. Within 24 hours, 99 percent of the creature was really dead and can not live again even warmed.
Next, yeast and worm embryos placed in less oxygen environment prior to be frozen in a state no oxygen. In this experiment, 66 percent of yeast and worms can live 97 embryos after warmed and given enough oxygen.
No oxygen conditions, according to Roth has resulted in stopping the cell cycle so that both types of living things into a dead faint. Supported cold temperature, then the biological cell cycle awake to remain stable during the dormant so it does not really die.
