Each cage, according to the expert, contains the hours which work on own dial, that is the recurrence of work of some processes differs from a 24-hour cycle, and melatonin gives the command for regulation of this cycle.

"Changes not only work of functional systems - cardiovascular, respiratory and so on and also the activity of a genome when we sleep changes, the activity of certain genes changes. Therefore if light is superfluous, and in the evening we use bright lighting, computers, gadgets, it shifts a phase of production of melatonin later hours, respectively causes in the person of a problem with a dream", - Kalinkin has specified.
