- <p>Maybe it's the hormones that make kids stay up late and sleep
- all day
- </p>
- <p> Hormones get blamed for just about every adolescent foible,
- so here's another to add to the list: teenagers may stay up later
- than younger kids because of physical changes during puberty, a
- study in the journal Sleep suggests. Until now, researchers (and
- certainly parents) assumed that night-owl adolescents were
- either being rebellious or pressured by friends. But a study of
- 458 sixth-graders, controlled for some social factors, found
- that students who were more physically mature chose to go to bed
- later than those just entering puberty. The same students also
- slept later on weekends than their prepubescent peers. The
- conclusion: puberty's biological changes may trigger an
- adjustment in kids' internal clocks, keeping them alert till the
- wee hours. Next hypothesis: it's hormones that make teens gab
- endlessly on the phone.
