While we sleep, our body continues to work. Some processes in it aktiviziruyutsya, others on the contrary — cease. To monitor the body during sleep we are not. But with us anything is happening.
Nose is sleeping
"My guns won't Wake up" — confidently say fans of a good night's sleep. In fact, harsh sounds, regardless of the nature of their appearance, take a person out of the stage, even the deep sleep, is based on this principle of the alarm clock. However, it is interesting that even the most active odors perceived in a dream, unable to awaken the sleeping, while their brains identificeret.
Most likely, the information received by the sense organs, gradually merge with the image projected by the brain, and while your spouse runs around desperately with a Cup of coffee, you just keep coffee drinking on the top of the Eiffel tower in his dream.
No pungent odor of pyridine or a pleasant smell of mint that were used in their experiment, the researchers of brown University (USA), awakened experience. This explains the large percentage of deaths are sleeping during a fire – people just don't notice an intense smell of burning.Movement during sleep
It would seem that the lying position and lack of need of physical and mental activity should be expressed in a state of absolute rest. In fact, the body continues to respond to third-party stimuli, such as light, noise, room temperature.
Because of gravity the parts of the body in contact with a surface subject to maximum pressure, why there is a need to change position several times during sleep. On average, a healthy person makes about 25 different movements within a few hours of sleep.
70% of them adversely affect the intensity of sleep, not allowing us to reach the deep phase, which is necessary for good rest and restoration of energy. In the deeper stages of sleep most muscles relax, but not become paralyzed, hold down the sleep from excessive activity. These processes explain the danger of sleep in a condition of alcoholic intoxication when the person for several hours does not change the posture, resulting in increased pressure to specific areas of the body and the prospect of neuropathy.Eyes sleeping
In the initial stage of sleep your eyes roll up, except for the light falling on the retina, even with half-open eyelids. By the way, the eyes can determine which phase of sleep is the sleeping.
In the phase of deep sleep, the eyeballs move slowly under the eyelid due to active blood flow to the muscles and internal organs. Phase of the deep sleep also is characterized by slow eye movements, but it also reduced heart rate and General pace of life.
And during REM sleep the blood supplying the brain is sleeping, aktiviziruyutsya thought processes, we see the colorful pictures of the dream and the eyes move in accordance with them. These processes are universal for humans and animals – observe the sleeping cat and you will understand the way to fly the Sparrow in her sleep last night.Tomorrow is another day
The brain, of course, not be disabled during sleep, but only into another mode of operation, continuing to control the processes in the body. Brain cells reduce the responsiveness to peripheral stimuli and begin working on the ordering and classification of information obtained during wakefulness.
The data is sorted are mapped to existing ones and are sent to storage in the relevant parts of the brain. Constant lack of sleep takes a time in processing information, whereby the data are confused, and people started to complain about memory status.
In 2004, German scientists from the University of Luxembourg taught a group of volunteers to solve mathematical problems of a certain level. Participants were asked about 100 tasks. After the first part of practical classes half of the students were offered a twelve hour sleep, while the other was awake.
In the second part of the workshop 23% bodrstvovanie offer the optimal solution to the task, while in the group of those who managed to sleep, the figure was 59%. This proves that during sleep, information is mapped and ordered, allowing you to find the best solution to the problem, which the waking man does not even know.
Height and weight
"Fly — so grow!", — said the mother in childhood. We hasten to please – experience in the dream state of flight does not necessarily, and if you measure the length before going to sleep and immediately after waking up, in the second case you will discover added 05,-1 centimeter.
During sleep reduces the load on intervertebral discs, they will rehydrate, stretch and take up more space without being subject to pressure of the body. Thus, straightens the spine, while in the evening, especially after prolonged wakefulness vertical, growth reverts to the original settings.
There is also the hormone leptin, which reduces hunger, the lack of sleep you will get the active production of the opposite hormone, ghrelin, which increases appetite. However for active work first need to sleep at least seven hours, and lack of sleep (4-5 hours a day) actively prevents the weight even with strict diet and physical training.
If you ate too much before going to sleep, it is best to sleep on the right side, this will allow the stomach and intestines to handle the load. Of course, to eat is not later than 3-4 hours before bedtime, and then the healing effect is guaranteed to you.Cleansing of the brain
There are two modes of brain activity – wakefulness, when a person actively thinks logically thinks and makes decisions, as well as a sleep mode or "washing" the cerebrospinal fluid spaces of the nervous tissue, when we rest.
The toxins are concentrated not only in the kidney and liver, but also in the cerebrospinal fluid of the body. It during sleep, the glial cells that surround and support neurons of the brain shrink, thereby increasing the intercellular space and increasing the flow of liquid out of the condition of the brain toxins.
In the dream limfatica system increases its activity about 10 times. If not, existing toxic proteins in the brain form plaque, leading to the development of Alzheimer's and Parkinson's. Unfortunately, the pumping of fluid through the brain tissue requires high energy costs and is incompatible with information processing, so living organisms cannot do without a full long sleep.
Sophia Loren claimed that the secret of her beauty – good sleep. We have no doubt of the veracity of this statement. During sleep, decreases body temperature and blood pressure, relaxes and restores cardiac muscle, the body is switching to the save mode and energy storage.
In addition to these processes, increases production of collagen, a protein that strengthens blood vessels and gives skin its elasticity. Because of these properties, collagen is often used in cosmetic procedures and creams, but nothing can replace their natural production by the body.
For this reason, the cream that contains retinoids, promotes the production of collagen, it is recommended to use before bedtime. In addition, in the dream you are upgrading tissues of the body, but production of growth hormone, bovine growth hormone, can interfere with elevated levels of insulin. Therefore, if you plan to get all the advantages from sleep it is not necessary to get used to the late dinner.

During sleep accelerated the cleansing of skin cells (especially in the first half of the night), improves oxygen metabolism, removes toxins and increases the strength of the fabric, which leads to reducing wrinkles, improving elasticity and visible anti-aging effect.published
