What influences our sleep quality

New findings have been found in sleep studies of different age groups, which show how the human body's need for rest changes throughout its life.

During puberty, people's sleep becomes shallow and shifts to the later half of the night, reflecting the large-scale reconstruction of neural connections in the brain. As a result of this reconstruction, the density of neurons in the frontal page, which is responsible for planning and suppressing inappropriate behaviors, decreased significantly.

Teenagers don't stay in bed just because they are lazy. If only school time could be adjusted according to its physiological changes.

I wish I could. For most adults, eight hours of sleep a night is enough, but for teenagers, if they sleep less than nine hours a day, most people will be listless the next day.

The sleep cycle varies from person to person, and it is also a key factor in the neurologic process of adolescents' transition to adulthood. The most frequent REM sleep is the last of the four cycles. Most of them go through three non dreaming non REM sleep stages before they reach REM sleep, and the whole process can be repeated four times in seven hours sleep.

For young people, it's this deep, non rapid eye movement and rapid eye movement sleep cycle that allows their brains to perform a series of "tasks" - one of the most important tasks is memory consolidation, which is an important part of learning new skills.

It is interesting to note that as adults grow older, they spend less and less time experiencing deep non REM sleep and REM sleep, and it is during this period that learning new skills becomes more and more difficult for them. You know what? The amount of sleep is also related to gender. Women's deep sleep quality is higher and lasts longer. There are also gender differences in biological clocks: Women's clocks are six minutes shorter than men's, which may explain why women on average are more early to bed and early to rise, and are more likely to define themselves as "early risers", which may also explain why women live longer than men.
