5 things that perhaps we should know to sleep peacefully
6. The country where you sleep least
The literal translation of this term is to be present in sleep (nemuri means sleep; the prefix i- indicates being present) and is used to indicate the act of falling asleep on the spot, in whatever context one finds oneself, even - and above all - in public, without this causing embarrassment.
Those who let themselves go to these moments of pause are very likely to do so because they have literally consumed themselves with work: the inemuri would, therefore, be a sign of dedication and complete surrender to the frantic rhythms that Japanese society imposes. The particularity, however, is that, when the situation requires it, those who practice inemuri are able to return to their activities ... in the blink of an eye.
7. Sleep oddities in the animal world
Some animals sleep mainly standing, others only moving, and then there are those who never sleep: dolphins and whales, in fact, have a particular ability, called alternate unihemispheric slow-wave sleep, which allows them to sleep with half their brains at a time, keeping the other half completely active and that senses the possibility to feel dangers and threats.
The idea of Bruce McAllister and Randy Garner was to break the record of absence of sleep, until then held by a dj from Honolulu, who remained awake for 260 hours in a row.
8. Sleep and height
9. Animal hibernation
During this period, the animals reduce their vital activities to a minimum: blood pressure drops, the heart rate decreases to a few beats per minute, breathing becomes slow, body temperature drops and metabolism is drastically reduced.
The Guinness World Records has also stopped validating primates on sleep deprivation, because of the risk of damage to the health of participants
If the winter hibernation is known to most people, perhaps, however, not everyone knows that there are animals going to summer: a sort of reverse hibernation which allows fishes, amphibians, reptilians and some small mammals to survive in the desert regions, where the too much heat and the prolonged lack of water would otherwise make life difficult.
10. Record of absence from sleep
After 264 hours without sleep (the equivalent of 11 days and 25 minutes), Randy Garner could finally close his eyes: he slept 14 hours in a row and then another 10 and a half, and then resumed his activities regularly, without recording - in the weeks and months that followed - significant physical or psychological effects.
