How and why we sleep?
The researchers began to uncover the secrets of the biochemical processes that occur in our bodies Vtzlmana to sleep. And the substance that causes drowsiness and sleep have not yet discovered, but the research underway to determine the nature of this article.
There are many opinions and speculations of the reasons leading to sleep.
They bounce back to before the days of Aristotle.
The conclusion of most people's ideas on this subject, is that the purpose behind sleep is to bring comfort, care and treatment of the case of wear and corrosion that affects the living body due to vigilance. It would have been more widespread consensus among most of those researchers that there is a substance thickens in the brain of the organism during wakefulness, even if the accumulation reached a certain limit, causing a sense of the need to sleep.
Was imposed according to this theory that the material causing the melt to sleep and fade away when the man sleeps. When built Aristotle's intuition along the lines of thinking, speaking in his interpretation of the sleep that vapors warm rising from the stomach, causing drowsiness and in this he wrote: «The steam facilities to process nutrition inclined by nature to move uphill, and that this explains how the cases of drowsiness freedom that occur especially after meals. The drowsiness followed by certain types of fatigue, because fatigue does act solvent, and solute (warm) do do before the digested food.
Contradiction in the theories
I have had many people believed that the blood can cause drowsiness, as pressure on the brain, causing stuffy. In contrast to this theory, the theory is another rumor says that contrary to the blood reaches the brain, or anemia brain is the one who brings a sleepy, and that when he sleeps the organism moves blood from the brain, and flows in other parts of the body, and in particular to the viscera. And soon led to the establishment of such views are conflicting ideas about how to obtain the best comfort for the night. And that some doctors at the time had recommended to sleep without a pillow, so as to facilitate the flow of blood to the head, and eliminate the cause of the anemia, cerebral, and recommended others make a lot of pillows when sleeping under the head of the sleeper, as the hormesis head this way will save the brain from the tension bloody compressor.
And contrast these ideas with the physiological, behavioral theories abounded related to sleep, in turn, were also common in many nineteenth century. Some have said that the lack of stimuli, for example, is the cause of sleep. The vigilance as they occur only as long as membership is always activated if the disappearance of the incentive alarm Nam body. That such an assertion seems to explain good if it was intended to explain why we sleep at night, and Qiloltna in the era of a rainy day, but this interpretation is unfortunately not correct, because it is scrutinized in the simplification of the ills of sleep: the man can sleep soundly even with a stirrer continuously, While that goes against Cree eyes of many who are in the ocean is calm.
At the turn of the century came physiological Swiss Edward Clapared behavioral theory, suggested imagination prevailing at the time. He said that sleep is not a negative response to the lack of excitement, and that the actors, like instinct, and claimed that the purpose of sleep is to prevent the euphoric including our bodies of accumulated wastes or consumers. Also it is reported Clapared an explanation of the length of what our bodies need sleep, he says: We wake up from sleep when we receive Kvaitna it. It is not difficult to refute this statement as fact self-evident, except that Clapared had re-raised the notion that something is actually happening on the organic produce sleep, thus paving the road the next generation of theories.
Materials sleep
At the beginning of the twentieth century, the theory is the most likely argument that there are natural substances that accumulate in the brain leads to sleep. Has been dubbed the «sleeping materials». The range of known substances such as lactic acid and carbon dioxide, and cholesterol, and Allocominat the toxic amines produced from animal metabolism, and urinary toxins. In about 1907, researchers made Frensan rural Legendre and Henri Pieron some progress in this field, has said that they were able to isolate the material from the cerebral spinal fluid for laboratory dogs, which had been deprived of sleep for periods ranged between six days and fifteen days. I was invited that article Alnomih toxic, because it is the injection of other dogs did not deprive them of sleep, succumbed to the lethargy.
It was this result and pursuant to the hinterland advocates claim that material as a sleeping bear activity between members of several groups to search, especially in Germany during the twenty years that followed. And made their claims about the existence of several materials of this kind, such as bromine and Hlavstop hormone. But none of them could not isolate a single substance can cause permanent memberships in the bedroom. As a result of frustration felt by those scientists because of their inability to make real progress, the order of their interest in materials sleep has faded in the end.
The researchers temporarily without a waiver from their research to the discovery of sleep. And that in the early days of the twentieth century, did not Tencthm to continue the search words they physiologists have discovered a new mechanism of sleep. This time they said that «the inhibitory nervous» cause of sleep, that there is any part of the sections of the brain brings sleep, so Bhdzh signals emitted from the senses and thus prevent muscle movement. Has drawn many researchers operate from the results of research conducted by Ivan Pavlov in the twenties of this century on the so-called «cortical inhibition». The opinion came out saying that sleep generally arise from Alvsaan Damageyen total, so that an effective deterrent to both the socket and exits sensory motor together. Pavlov and wear to the ideas of earlier when he said this made clear his view that this ban and that Alatalat occur partly because of the response to the monotony.
Sleep centers in the brain
We have a group of Alvezaologin exploration designated centers in the brain the main work is to bring sleep. Pavlov has vehemently denied the outcome of the work of this group. However, the discovery sentence alert in the brain in the late forties, a sentence passing in the center of the brain and his successor, has indicated that most of these centers Alnomih list.
Now the focus has become more concentrated and one of the most prominent fields of research on sleep. It was found that the brain's number of centers, sleep related, which is spreading beyond the sentence, alert, and that some of these centers with a bearing time day and date solutions drowsiness, and some are related to sleep rapid eye movement, when the accelerating movement of pupil rights under the eyelids and starts dreaming. Some of these centers is linked to sleep, which does not occur when rapid eye movement does not occur when dreams. There are even within the brain stem regions that affect Mthizatan to sleep, one keeps on the vigilance of membership, and the second brings sleep. These discoveries show the complexity of the methods of supervision nervous to sleep.
Most of the evidence obtained so far, says that sleep is not limited materials and presence on the sleep centers, but is distributed over the whole brain.
Materials are the rates bed to sleep
Based on the discoveries made about the materials that sleep may perhaps say that the articles of sleep and most of its centers is not only rates of sleep, that is, they modify and regulate the timing of sleep and help to regulate the composition. Like that statement by way of illustration and analogy when talking about materials sleep this way, hit the examples of the stimuli and their impact on the process of eating. Valmnfrat and appetizers and some drugs with the smell of food all of these are active need to eat. But can not explain the reason for our need. It is, even after polycythemia and fullness that can entice Bastzadh eater, but this food is in excess of need, no need to man it, it does not benefit health.
It must be emphasized here that the materials mentioned it to sleep, not sleeping pills, but are endogenous substances in the brain bring sleep.
Among other research on sleep conducted by Dr. John Pappenheimer that he was denied some of the goats of sleep, and found that this deprivation has created in the cerebrospinal fluid have a substance was unknown until that time called the factor (factor-s) (s) was injected to this article Laboratory mice, rabbits Vnamt quickly. In the early eighties the researchers managed to pass her son in a laboratory isolate the factor(S) from human urine, but they found that 3,000 liters of urine does not produce only 7 million of a gram of this factor. It may be hard to believe that this small amount of the agent (s) are so strong was enough to produce five hundred doses.
The rabbits were injected by the laboratory, causing each dose to a significant increase in the duration of their sleep the abstract of the speed of movement of the pupil, so they slept for a long time amounted to six hours. It was found that this extra sleep was not artificial, it was a natural sleep. Interestingly, the impact of this factor may be compared to the normal of the impact of sleeping tablets. Valeranb which succumbed to sleep on the impact of Hvtha factor (s), unlike what happens when you bring the disk hypnotic sleep, it was easy to wake her from her sleep, where they eat and Ttfly during vigilance, then return to sleep long. Jim Kruger was the U.S. to complete what he began Pappenheimer's research indicates that the factor (s) referred to was
Peptide Moramal
(Muramyl peptide), a substance very similar to the bacterial cell wall materials, which led researchers at first to think that factor (s) was not only a product of the bacteria had contaminated the cerebrospinal fluid and urine. However, research conducted by Krueger and his colleagues have demonstrated a strong indication that the brain has produced this article as part of the biochemical.
The scientists artificially produced peptide Moramal. Kruger and how one of these types of material processed, a Daeptad Moramal, the reason for a longer period of sleep the abstract of the speed of iris in rats, rabbits, cats and monkeys laboratory. Did not try this article manufactured in human subjects. It was noted that such an article did not affect the other daily biological rhythms in the body such as the degree of heat. But limited impact on the cases of sleep and wakefulness.
It turns out that to this article and another job, they incite wholesale horsepower in the body. To show that the loss of sleep does not damage the wholesale horsepower, and occurs only minor alterations to the forms of response.
The diets between sleep and wholesale horsepower is still mysterious far from clear, and perhaps the occasional passing diets. For example, there are certain centers in the brain to sleep, such as the center, cheap or hypothalamus also affect the responses horsepower. The damage in this position cause insomnia or excessive sleep, depending on where the damage occurs.
The researchers of the Japanese at the present time a prominent position in the field of materials research for sleep. Has identified a number of these materials, notably so-called «article establishing the bedroom» and substance Albroosta Glandin article establishing the bedroom close to a structure factor (s) have been derived from the trunks of the brains of mice, laboratory deprived of sleep, which is composed of four components . The most prominent of these materials Alaordin material, which caused the surrender of these animals to sleep long. Did not try any of these substances on human beings. The impact of these materials are all on the body temperature has not yet revealed the full disclosure although some had created a confusing situation, such as (dsip) which show that lowers body temperature in animals if it is in a cold environment, but brought in a warm environment. There is no date for the causing agent of sleeping in a comprehensive manner with all other creatures, this article has not yet discovered. But the thing is known that there is a strong material impact in this area, and other weaker force, including the hormones insulin and some of the viscera. Who knows, perhaps Aristotle was not very far from the truth when he said that sleep arising from vapors rising from the viscera.
How much of human sleep
If the person wakes up from sleep may be taking enough sleep, regardless of the hours that Namha.
Is it true that you need to complete eight hours of sleep a day, otherwise you will look pale, confused mind, and will appear dark circles under your eyes? Do not you know people who sleep in one, wake up and active in the sixth, while there are others who do not even last them ten hours sleep, what will make the «eight» is the magic number of hours of sleep.Dr. Oasmt Kara_an answer: «The eight hours is the average.
Most adults sleep between 69 hours, and all this naturally. But sleep for longer or shorter than this does not necessarily mean the presence of a health problem, has known people who slept for two hours only, however, do not suffer from any problem ».
Generally, we sleep less as we get older. Valoulid sleep eighteen hours a day, and then falls circles many hours sleep to seven and a half hours in adolescence and decline more after the age of thirty men and fifty women. When both sexes up to the mid or late fifties low rate of sleeping hours to less than six hours only.
Different sleep patterns vary by age as well, Vllnom are two main: «eye movement regular» and «eye movement, irregular» These are divided in turn into four stages according to the depth of sleep Valmrahltan first two will be sleeping in them lightly, while it becomes deeper in the fourth stage «stage of deep sleep» The child spends 50% of hours of sleep at the stage of deep sleep while the adults may not be up to this stage of sleep ever. This is quite normal, so no sense of what they might call insomnia, but the natural symptoms of aging.
If you feel that you are alert and active have taken the proficiency of sleep regardless of the number of hours that Nmtha or that I used it, it is true that there are circumstances temporary may change where you need to sleep as indicated by Dr. Jerrold Maxven author of «sleep right» as ease the need to sleep in cases of stability and comfort, while the increase in times of illness, anxiety and sadness. It is natural to find that you sleep more during periods of grief, or if you lose your job, or lost a friend, while you sleep less when you feel happy and relaxed, in any case should be signs telling you what is happening you will feel sleepy as well as other indicators, a person Alm'zaji may become more mood, whereas another person becomes anxious and Mtavva.
What happens when the deprivation of sleep for a long time.
Most researchers agree that the compensatory sleep. Compensatory Why? ... Many say: it compensates the hormones that relate the process of building the body, which provides the energy necessary for vital activities, where this process at the peak of effectiveness during sleep .. It is well established that the body finds it more difficult to do strenuous activity, if deprived of sleep for a long time.
If this happens to the body, what about the brain?
The cerebral cortex, where the most complex mental activities, more parts of the brain need to sleep, and the most affected from lack of sleep is a long mental tasks. But all this does not mean that sleep for longer periods helps the body and brain to perform their mission better, because the shortage does not happen only when the deprivation of sleep for a long time.
Why we can not sleep sometimes
The research on sleep, and laboratories specialized in affairs, have led to a number of exciting discoveries.
But it is strange that the most important questions raised is «Why do we sleep?» A man spends one third of his life asleep, however, he does not know very little about sleep. Moreover, much of what we think we know is wrong, and the fact that sleep was until recently full of mystery and speculation.
Experts say that during sleep the body gets rid of waste, and the restoration itself and store the energy to spend the next day. This seems reasonable to say, but has yet to prove it's true. There is no evidence at all that is true. There is no scientific study of the show that the body needs to sleep to stay healthy. The truth is that no human being uncertain of the role that sleep plays in the body of any living organism, there are animals does not sleep at all, and most people need six hours or eight hours of sleep each day, but there are cases of people who have enough less than one hour of sleep.
The common belief that sleep is essential for mental health and that sleep deprivation causes the collapse has not been proven scientifically.
There are healthy people kept awake for weeks, with the result that they felt very sleepy, but they did not get sick, and did not become infected Bluth mentality. The lack of sleep, of course, create tension in humans, but tension is not more than is caused by other symptoms, and after a generation of research was proven by scientists only one thing for the purpose of sleep: it eliminates drowsiness, people are sleeping because they feel sleepy, if not sleep increasing in drowsy.
There are other aspects of the research was more revealing of the facts. Has left many of the discoveries about sleep from sleep laboratories, where he teaches patients or volunteers while they sleep. The EEG sensors attached to the skin of their heads along with other bands to measure breathing, heart beat and movements.
One of the first discoveries that came in the laboratory as it relates to that which occurs during normal sleep. Most people think that the brain during sleep depends on the performance of its functions, and so the body relaxes completely. That there is something of truth in this saying, but which turned out to be sleeping for the most volatile than previously thought. Valenobac brain clots and heart and asthma attacks occur most often during sleep, people with ulcers of the stomachs secrete acid during sleep than during waking bears.
Alerq was, until recently, the mysterious neurological problem, and that the best cure is reassuring in the same person with insomnia, or doing exercises to relax, or give him sleeping pills. Today, aware that insomnia is a medical and psychological situations are different. And that most causes fall into six categories: Alerq false, drugs, usually, the problems in the vital body rhythm, contraction, and medical problems.
What causes insomnia???
Alerq false
Research laboratories has shown on issues of sleep that a third or half of the people who suffer from insomnia are not infected with it. It is proven from the observation and research that many people who come to the hospital asking for a remedy against Alerq fall asleep quickly, and spend a quiet night, but when they wake up in the morning, returning to the complaint that they had spent the night disturbing the other.
One does not know why these people thought that their sleep is bad, while they do not suffer anything like that, but what is clear is that doctors can not settle for descriptions of the same people who are sick for insomnia. It said that many of us do not know how to sleep.
Drugs
The sleeping tablets are useless for a large part of people who say they are living with insomnia. It is dangerous for any human being infected with psychological problems. These disks should not be used in any case the long-term, but may be useful for cases of short-term.
The description of the sleeping tablets do not cure insomnia. These drugs cause insomnia. It produces a kind of tiny convenience, it is best described his forgetfulness does not sleep.
And grains that are easily bought without a doctor's prescription to help a person sleep, not sleeping pills at all. As some of the anti-histamine, which is similar to drugs prescribed to treat allergies and some calm the emotional diseases. The side effects of these drugs, drowsiness, and therefore they are often sold as drugs to promote sleep. The few people that are affecting those disks, but not useful for most people.
Usually
Most people feel sleepy when the harbor to bed. But some of us do not feel sleepy so quickly, the problem is that everyone needs to be different from the one for others. There are people, they are few cheap, is not only less than ten hours of sleep, but others just last them five or six hours.
Of the most common complaints heard by the doctor: «I can not sleep before the passage of long hours» or «I wake up after a short period of sleep then I can not then come back to it». The people who have complaints of this type very rarely feel anxious or illness or depression.
Most of them does not need as much as you think it necessary for them to sleep.
