What’s wrong with teenagers, if they sleep longer than usually?
They are not lazy, they just can do nothing with it. In the childhood the hormone melatonin which is responsible for the cycle “dream-cheerfulness” is produced by a strobiloid gland in the early evening. When the puberty period comes at the age of 10-14 years, melatonin is made later – at 9-10 in the evening. Such change often prevents teenagers to go to sleep before 11 o’clock in the evening, the expert of a teenage dream, the candidate of science Mary Ey Clarkson says. As teenagers need nine and more hours of sleep, they compensate late withdrawal for sleeping by the fact that they sleep longer than usual.
