EDITOR’S NOTE: Space Coast Daily is delighted to welcome Dr. Christopher Johnson as a guest contributor on issues of child health and well-being.

That’s a show stopper of a headline from Reuters. There are more and more reports emerging of the bad effects of adolescents not getting enough sleep.
The research has become sufficiently compelling that many high schools, including the one my son attends, have shifted their starting times to a bit later in the morning. More sleep clearly improves learning.
But this new study flips things around and focuses on the bad social results of not getting enough sleep.
The study authors use the more mundane title of “Dose-dependent associations between sleep duration and unsafe behaviors among US high school students.”
It was a very large survey study (over 67,000 subjects) spanning the years 2007-15. The survey correlated risky behaviors with hours of sleep. One of the things that makes it a particularly strong study is that it showed a dose relationship. That is, if one thing is related to another, one typically sees more of it as the dose, in this case sleep deprivation, increases.
The threshold for seeing the ill effects of insufficient sleep was found to be 8 hours. Teens who got seven hours of sleep a night or less were 28 percent more likely to drink, 13 percent more likely to smoke, and 17 percent more likely to try drugs other than marijuana, compared with adolescents who got at least eight hours of shut-eye.
Of course, there are potential confounders, as with any study that suggests an association but not necessarily causality. That is, a family situation in which a child doesn’t get enough sleep may simply be associated with risky behavior rather than causing it. But my conclusion is that, although this association was a bit weak, it was consistent and showed a dose relationship. It’s just one more reason to make sure your adolescent gets enough sleep.
