Home sleep stages in man young
- Lack of sleep. EEG swinging between the two major patterns during wakefulness. The first value of voltage is low (about 10-30 Micro Vault) and fast active (16-25 Hz), often called the pattern of activation or asynchronous mode.

 And the other pattern is the pattern frequency between 8-12 Hz (most of the people within the scope of 8 Hz, either 12 Hz is among university students) electric voltage up 20-40 Micro Vault is the so-called alpha style. It usually controlled style Alpha when a person is relaxed and his eyes closed. 

Pattern of activation when the person is alert and his eyes open, and he scans the visual surroundings. Depends on the amount of reading and the value of the optical scanning EMG, and may be high or moderate, depending on the degree muscle tension.

- Phase 1.
 Declining pattern of Alpha, and the pattern of activation is rare, while reading an EEG low voltage and mixed pace of activity, the extent of 3-7 Hz, and show a slow movements of the eye. And the value of EMG medium to low.

- Phase 2. Otherwise continuous background of low-voltage, appear in the EEG activity and distinctive flashes in the range 12-14 Hz called sleep spindles. Eye movements are rare, and the value of EMG low to medium.

- Phase 3. Shows a wave with a high amount of value above 75 Mlavolt called delta waves in reading EEG, while the remaining Aqraot EOG and EMG were also unchanged.

- Phase 4. Delta wave starts increasing even become the main wave and the huge scale on EEG.

Sleep is regulated in specific regions of the brain and the influence of hormones in the Alhaaboethelms arise from the brain such as the hormone melatonin, which you configure a special organization for bedtime, depending on the amount of lighting in the vicinity of the person.

Based on studies conducted on brain waves during sleep, sleep is divided into five sections, namely:

Non-rapid eye movement stage 1 an initial yawning and sleep and go to the second stage of sleep.
Non-rapid eye movement 2, in which at least the level of awareness of external events, and this stage is 45% - 55% of the time Tom Gross
Non-rapid eye movement 3 and constitute about 5% of the total duration of sleep.

Non-rapid eye movement 4 and constitute 15% of the total duration of sleep is a period of deep sleep, which is difficult to wake up from it and this is the period in which they occur during nightmares and sleep walking.

Rapid eye movement stage on which the new sleeping dreams and this period is the last third of the sleep cycle.
This takes five stages about 90 minutes and is repeated several times during the overall period of sleep is worth noting that the dreams take several minutes to every 90 minutes after the start of a new cycle of stages from rapid eye movement I and ending with the rapid eye movement.

Differ from the needs of the individual to sleep from one person to another has used the period of 8 hours on average for a period of sleep needed per day and led some of the research that has to be held at the University of Harvard is that lack of sleep may lead to increased rate of certain diseases such as high blood pressure, stroke, heart attack and cancer There is a tendency in people who work at night and sleep during the day that they have less immunity to some diseases such as breast cancer Btaser change the circadian hormone, for example, an increase of Wee-1 cells proliferate and lead to cancer or lead to change Ketatamen Alanastzaa or anesthesia.

Generally divided cases non-natural sleep in the following cases:


  • Narcoulibsa
  • Chjnat the lower limbs during sleep
  • Stop breathing during sleep
  • Sleepwalking

 Tips for sound sleep

Sleep is a natural process we do every night.Since human beings are not either; some people to sleep whenever and wherever he wants, while others find it difficult to sleep, and sleep when he does not enjoy the comfortable and do not restore its activity. There is a certain lifestyle and certain food habits, in addition to individual behavior helps to sleep properly, as these factors can impact positively on the proper sleep quantity and quality.

 The conversation here will be limited to the behavioral aspects of treatment, We will not go for organic disorders.

There are misconceptions about sleep should be clarified. The average person requires from four to nine hours of sleep every 24 hours for a sense of activity in the next day.

 In any case, the number of hours of sleep needed by the human vary from person to person. Many believe that they need to sleep eight hours a day, and that as they increased the number of hours of sleep whenever it is healthier, and this belief is wrong.For example, if you sleep for five hours at night and feeling energetic the next day you do not suffer from sleep problems. Others attributed his performance deficiencies and failure in life some things to the lack of sleep, leading to over-focus on sleep, and this focus prevents the owner from obtaining a comfortable sleep at night and confined in a closed circuit. We must therefore distinguish between the lack of performance resulting from lack of sleep and lack of performance caused by other things, such as increased pressure at work and inability to cope with the increase in tension, and others.

Facts About Sleep

  • The remaining parts of our brain is active during sleep, warn us of the dangers.
  • The amount of energy that we provide and we are sleeping is a very small.
  • Essence the brain related to sleep more than it relates to body.
  • Closed parts of the brain almost entirely during sleep.
  • Sleep gives us an opportunity to organize our memories and enhance our experiences we are going through during the day.

Result in high noise intermittently intermittent light sleep does not help the body to restore its activity does not give him the opportunity to get on the stages of deep sleep. Can get rid of this noise so-called "white noise" to be a voice in the background constant intensity and constant voice of a fan or air conditioning.

The strong light in the bedroom of the factors that affect sleep. Therefore, preferably the bedroom light is dimmed.

Avoid repeated consideration to the alarm clock, because that may increase tension and insomnia then, avoid the use of the hours that lights up at night.
