Sleep is a rest not only for our body but also our brain. The fact about the mechanism has not yet been revealed fully, but scientists believe that during sleep brain “cleans” and “resets”, it gets rid of unnecessary information and organizes the necessary.
Good sleep is an achievable dream. The process of sleeping is so natural that we feel as if we know everything about it. Meanwhile, there are so many things known only to specialists. Have you ever imagine the number of entertaining and scientific facts about sleep? Here is a list of 11 the most amazing facts about sleep, which you probably did not know.
11 A Person Can Learn To Control Dreams
Lucid dreaming is a phenomenon that Stephen LaBerge is studying. It turns out that we can improve the ability to understand what we are seeing in the process of dreaming and how we see it, and even consciously control it. This sleep fact research in this relatively new field shows that lucid dreaming is the result of physiological changes in the brain together with an act of will and intention of a sleeping person. As a result, the element of self-consciousness is added to a sleeping process.
Often knowing that we are sleeping awakes us, but if you’re lucky or know the necessary tricks, you can continue to dream.
10 We Are All Lunatics
Every fifth inhabitant of the Earth was walking during sleep at least once. During a sleep, people do almost all the same as during the day: talk, eat and drive a car.
But if it repeats, a person may have a sleep disorder. People suffering from this disease can move, but they cannot recognize faces, they do not hear cries, and they feel no pain. In this altered state of consciousness, they are capable of anything.
9 Teenagers Cannot Sleep Early
The cause of teenage depression and aggression is a sleep deficit. During puberty, circadian rhythms are shifted by three hours backward. It turns out that at 10 P.M. it is not only difficult for teenagers to have a sleep, but also biologically impossible.
Because of this jet lag, it is completely pointless to require quickness of wit from teenagers in the morning.
8 Dreams Are The Second Reality
Dreams are seen and felt as a reality because the activity of almost all the parts of the brain is reduced, while the sharp decline is observed in the important area – planning, logical thinking, and problem-solving. The inaction of the part responsible for logic explains why we lose our orientation in time and space in a dream, and why we have no doubts about the reality of the situation. For example, we are not surprised by the fact that suddenly a dog turned out to be a taxi driver and why it wears armor.
Dream content can be strange and bizarre because the logic also “sleeps” at night.
7 A Person Learns While Dreaming
Sleep plays an important role in the assimilation of information and skills. It seems that the light stage of sleep is responsible for improving new skills of the musicians, athletes, and dancers. And it comes in a day or two after the first training of this new skill. Thus, to get the most benefit from a workout or exercise, you need to sleep well at least during the first night after the initial development of a new skill.
6 The Biological Clock Does Not “Break”
The American scientist Nathaniel Kleitman, who was an immigrant from Russia, spent a career studying sleep. Once, he spent a month in an underground cave. Nathaniel Kleitman wanted to find out if the absence of external signs of time (sunlight, dusk, darkness) influences the biological clock.
It turned out that our biological clock does not depend on whether we can see the sunrise and sunset or not. It is set to the sleep-wake cycle of 24 to 25 hours.
5 Lack of sleep may cause death
Lack of sleep can be murderous. Rats checked it. As a result of experiments, the researchers concluded that long vigil depletes the body; it ceases to regulate body temperature, which leads to death. For the obvious reasons, no one figured out empirically whether a person could die due to lack of sleep. We can only talk about the short-term experiments of government agencies. For example, in Guantanamo CIA interrogators prevent prisoners from sleeping. They were tied together and forced to stand for more than a day.
During the day, blood pressure of prisoners increased. Then there were problems with the metabolism. Body temperature decreased, and the immune system weakened. The most amazing thing is that this destructive process can be stopped at any moment. It is necessary to sleep for a couple of hours, and all the consequences of lack of sleep disappear.
4 Earlier People Have Had A Two-Phase Sleep
Every day people fall asleep after sunset and woke up after midnight. This was the first phase of sleep. The man was awake for about an hour before going back to sleep until the morning (it was the so-called second phase of sleep).
This night break was common, and each person spent it differently: someone was praying, someone was reading, and someone was having sex. The latter option was probably the most common. In the XVI century, a doctor found out that the workers give birth to several children because they make love after the first sleep.
Numerous experiments have proved that if a person had the chance, he or she would divide sleep into two halves. In the world, there are still people who sleep this way. They just live in areas with no artificial lighting, computers, and televisions.
3 Men Snore More Often
Men usually sleep better next to a woman than alone. Maybe the reason is that they just enjoy the emotional intimacy because they do not have to listen to the snoring of the spouse. Women not only snore much less frequently than men but also sleep more advertently. As a result, women suffer from insomnia more often than men.
2 Sleep Is Training
Dreams are the playground for our mind. Anxiety and unpleasant dreams are just an ancient defense mechanism. We are experiencing bad events in a dream to be ready for them in a real life.
1 Men And Women See Different Dreams
We all have dreams, but men and women are dreaming differently. Men more often see representatives of the same sex, and women see approximately the same proportions of both sexes in their dreams.
Nowadays, science sheds more light on the nature of sleep and dreams, and other efforts of the brain that make us who we are. And further, it will be even more interesting to know the unknown facts about sleep.
