11 Amazing Facts About Sleep

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

11 Amazing Facts About Sleep

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.

8 Dreams Are The Second Reality

11 Amazing Facts About Sleep

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.

11 Amazing Facts About Sleep

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.

5 Lack of sleep may cause death

11 Amazing Facts About Sleep

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

11 Amazing Facts About 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.
