What is the difference between a quick dream from a slow: ratio and characteristic of quick and slow sleep

Sleep - a period of time when a person rests and is in an unconscious state. It is believed that during this period the brain is at rest.

In fact, many diverse processes occur in the entire body, for example, hormones are produced that are responsible for growth and sexual development. Sleep is divided into two types: fast and slow. It is from them that cycles are obtained, which are repeated approximately 5 times during the night. Consider the types of sleep in more detail.

What does slow sleep mean, what is important?

• Slow sleep is a period when absolute relaxation occurs. Provided that a person sleeps no more than 9 hours a day.
• If you wake up for this period, he feels fatigue and breakdown, most likely the problem is a lack of slow sleep (MS).

With a lack of slow sleep, health problems begin, for example:

• the body's defenses are reduced;
• memory worsens;
• new information is hard to study;
• there is a large load on the nervous and endocrine system;
• the body slowly produces the necessary hormones.

Lack of sleep can cause pathologies of the heart, diabetes, dementia or Alzheimer's disease.

During the phase of MS:

• tissues are restored and muscles relax;
• "Recharge" the brain;
• memory structuring occurs;
• blood pressure and temperature are reduced;
• breathing becomes calmer and less often.

This type of sleep is three stages. The stages of slow sleep are designated by Latin Buki N. The first stage of slow sleep (n1) or a nap - The bordering stage between the beginning of sleep and wakefulness.

At this time, such phenomena begin:

• sleepy paralysis;
• sleepwalking;
• symbolism (somnicvia);
• hypnagogical jerk.

The second stage, moderately deep sleep (N2) - The falling asleep is completely turned off from reality. The muscles relax, body temperature decreases. The duration of slow sleep in the second stage is 20 minutes.

Stage III MS (N3) - deep dream. Now the breath is rare, the pressure is low. The body regenerates tissues, produces hormones and removes metabolism products. The brain at this moment generates memories. Now they are no longer short -term, but moved into long -term "archives".

• With the onset of the slow phase, the restoration of forces is performed. A person, often waking up in this period, loses the ability to “restart” the brain.
• As a result, he will have poor health, he will not be able to concentrate, increase nervousness, apathy and irritability will appear.
• With constant lack of sleep, there is a risk of serious mental pathologies.

What is a quick dream?

• After a slow sleep, a quick dream comes or, as it is also called, phase of quick eye movement (BDG). This phase occurs after the start of sleep in 90 minutes.
• With the subsequent BDG cycle, increases. With the onset of BDG dreams are the most memorable. If you look closely at a person, then with a quick dream, his eyes will move. In some cases, the sleeper can move the limbs, while the muscles are not tense. The body temperature is constantly ranging.
• The brain analyzes the information received per day. It was proved that the activity of the brain during BDG is identical to the period of wakefulness. Memories are formed, abilities are fixed.
• The BDG phase is well suited for awakening. At this time, the body is preparing for wakefulness, the connection between physiological microprocesses in the head and consciousness is included.

What is the difference between a quick dream and a slow dream?

• A distinctive feature of slow sleep from fast is the difference in brain activity. Throughout the BDG, the eyes move, and with a slow - eyeballs are almost in place. Dreams that dream during a quick phase are more often remembered.

The duration of the BDG phase is 10-20 minutes. The slow stage of sleep is 90 minutes. As a result, it turns out that the cycle lasts up to two hours. For a full resumption of forces, a person needs 5 such cycles (70%/30% of the cycle - slow and quick dreams, respectively).

• The duration will change, because the slow dream will become decreased, and the fast sleep will increase. The most prolonged dream begins in the BDG phase in the early hours.

How to increase slow sleep?

• Now many people have a priority with effectiveness and ability to work.
• Sleep deficiency negatively affects well -being, health, mood and ability to work. Therefore, in order to keep up with everything everywhere, to be cheerful and positive, you should increase the duration of slow sleep.
