Idée du nord

Den 8-årige pojke som just överlevt att ha varit under vatten i 20 minuter klarade sig antagligen för att lungorna andades in det iskalla vattnet och sänkte kroppens syrebehov. Jag vet inte, men förklaringen låter helt overklig (på ett bra sätt), och mycket science fiction.

[B]reathing the chilly water can also save the brain, the organ most at risk during drowning. The body's impulse to respire is so strong that the lungs will continue breathing water in and out well after submerging. Studies on canines have found that mammals can continue breathing water for up to four minutes. Circulating that icy water through the lungs, Dr. Giesbrecht has found, cools the brain and reduces the body's core temperature.
In warm weather, if someone were to stay submerged in an outdoor pool for more than four minutes, “they will either be dead or have severe irreversible brain damage,” Dr. Giesbrecht said. “But the cooling of the brain increases the time you can go without oxygen. The tissue, as it gets colder, requires less oxygen.”
