Possible link between lack of sleep, risky behavior in teens

New research by the Centers for Disease Control finds most teenagers do not get enough sleep, putting them at greater risk for a slew of unhealthy behaviors.

The CDC says that includes physical inactivity, fighting, substance abuse and serious consideration of suicide attempt.

Researchers analyzed results of a high school survey and found that nearly 70 percent of the teens were not getting the recommended eight hours or more of sleep on week nights.

Scientists say public health intervention is greatly needed and the consideration of delayed school start times may hold promise as one effective step in approaching this problem.
