Why do humans sleep? Promotes learning and memory formation.

It was previously reported that we have been sleeping for almost a third of our lives.
but why do we sleep? There is no denying that sleep has a basic preventive function, because during this time neurons synthesize proteins and other molecules to help them recover and maintain their function from the wear and tear they are exposed to when awake, Western media said.
However, one of the most important functions of sleep is to promote learning and memory formation.
Mammals are so demanding sleep that natural selection has found ways to ensure sleep, even if it is incompatible with other important activities, According to Spanish newspaper El Pais on December 24.
sometimes, we are surprised that our ability to learn improve without practice, and that we feel like God.
in an experiment that proves this, the participants were learning to type in a sequence of numbers.
they did three exercises, each lasting five minutes, and took a 2-minute break after each exercise.
the experiment, whether conducted day or night, over time can improve the speed and quality of tasks and significantly reduce the number of errors.
now we know that the magic behind learning progress is sleep.
when we remember something, we reactivate the memory of it and make it stronger and more stable.
However, in a quiet state every day, especially after we go to sleep, the reactivation of what we learn during the day can also occur unconsciously.
studies have shown that neuronal activity sequences performing certain learning tasks in the hippocampus, which are closely related to memory formation, also repeat spontaneously and more quickly during subsequent sleep.
reported that recording repetitive activity in learning neurons is the same as repeating learning to better record the effects of neurons.
long-term memory is best formed during sleep, and sleep to consolidate what you have learned does not require you to sleep for eight hours at night, even if a nap or two can work.
all of the above, memory can improve even if we haven't practiced for a while, because in a sense, sleep is a special practice.
, recent experiments have shown that people who stay awake all day are significantly less able to learn, while those who slept for nearly two hours that day showed significant improvements in their ability to learn digital tasks.
so sleep is good for memory, whether it takes place before or after learning.
related animals in the strange way of sleep Some scientists in order to find out why sleep, observed the natural animalsleep way, but not to observe the good, observation found more complex.
because although sleep is common in animals, the way they sleep varies.
bats spend 20 hours of the day sleeping, while horses seem to use the so-called "Da Vinci sleep method", where a few naps in a day is enough, adding up to three hours; and even reptiles, fish, fruit flies and nematodes have quiet breaks in response to reduced external stimuli, although the scientific community is still hesitant about defining it as "sleep."
", "Sleep is an important result of animal adaptation to the environment, and is influenced by evolution."
" Lei said the diversity of animal sleep patterns is mainly reflected in two aspects: the degree of activity between day and night and the length of sleep.
, for example, owls come out day and night, while bellingbirds come out early in the morning.
usually grass-fed animals at the lower end of the food chain, sleep ingested shorter, while large predators at the top of the food chain, such as tigers and lions, sleep longer.
herbivorous animals have a short sleep time and a fast sleep cycle conversion that facilitates longer food intake and escapes the risk of being caught by predators.
and large predators can sleep to reduce calorie consumption and achieve the effective recovery of the body. another interesting phenomenon in animal sleep,
he says, is cerebral brain sleep.
some mammals and birds, such as dolphins and warships, sleep in half the brain and stay awake in the other half.
they can alternate sleep between the two hemispheres of the brain to meet the need for long migrations and avoid arrest. "In recent years, we have found that humans exhibit similar half of their sleep and half of their waking conditions under special conditions, such as entering unfamiliar sleep ingress.

," Lei said.
sleep so polymorphism, let those who want to find a universal ultimate explanation for sleep is very distressing for the researchers.
, however, experts point out that sleep in many species has something in common - changes in the brain, such as loss of all or part of consciousness in sleep, which can impair cognitive function.
to find out about sleep, you have to study the brain and nerves, but in the field of neuroscience there is still further research, and everything is still elusive.
