The main problem is that the water in the cells of the human body freezes in the form of crystals. The crystals damage the cells and structures within cells. Cells burst. There is no method to prevent the precipitation of crystals of water so far. If the cells burst, our medicine does not know how to repair such damage. It will be so for a long time, unfortunately. If someone froze, then we can not go to defrost.
But I'm optimistic message. Just being in the cold if you do not freeze, causing the brain reduces the need for oxygen so that it is possible to restore to life, even after quite a long time. Longer than those famous three minutes, in which it is necessary to restore circulation to an unconscious person.
I hope that this knowledge will never be needed.
While the low temperature (of course not below 0 C) reduces the need for oxygen, and slows down the metabolism, is it possible that it increases the lifespan too?
ReplyDeleteThank you for your comment, I am glad to see it. It is first comment on my blog “Interesting Medicine” :)
DeleteIt is a good question.
I am not sure about lifespan. It is possible to check an average life length in different climatic zones.
But...
I know about the average time of puberty. In Poland, the country where I live and work, girls get first menarche in when they are 13 years old (on average).
In worm countries, such as Italy, it is 11-12 years. In colder countries, such as the Scandinavian countries, it is 14-15 years.
I looked at the average life expectancy in individual countries in Wikipedia, but I see great disturbances associated with political and economic situation in the country.
What a pity.
