Insomnia or Sleep Disorder - a problem faced by almost all people.
Insomnia is characterized not only by lack of sleep, but also the inability to sleep well and can also include difficulty falling asleep, duration of sleep or lack of early awakening followed by the inability to fall asleep again.
Insomnia - this tension. And there is such tension in the hypothalamus - a small region of the diencephalon, which is the central link between the nervous and endocrine systems.
It hypothalamus controls sleep and wakefulness. If you annoy one or another region of the hypothalamus, then very quickly we are able to make sure that the organs or systems, controlled by the hypothalamus to react to this irritation. For example, if you irritate the hypothalamus, which is responsible for our emotions - fear, anger and despair, as a result we get a stomach ulcer, because this irritation can abundantly allocated gastric juice, which erodes the stomach wall.
Thus, sleep controlled hypothalamus. If a person has insomnia, then he has a program such as "I do not want to sleep." This, of course, conditional, but this program is not direct. This is because the hypothalamus it understands. And for this program is anxiety, anticipation of situations scrolling past and upcoming.
Man thinks and analyzes at a time when you need to sleep, because during the day he had no time to think about it. This is the fatigue. Many exciting moments have access to your mind, obsessive thoughts, coming at a time when the brain wants to settle down.
They become independent programs, and the person causing the program when it is in a relaxed and intimate setting. Sometimes it happens when a person over a period of time chooses consciously intended time for sleeping, for their own reflection that becomes a habit, and the brain is fixed as a team to "work". That is, you set your own brain program, and he performs them. If the subconscious program - system, then it will come back to you every time you will approach the time for sleep.
CONCLUSION - We must understand that bother you in your memories, in your experiences. What is annoying you so often have to think about it? You need to sleep just watch the thoughts without identifying with them.
