Gaming and Internet activity are more likely to have a negative impact on self-reported teen sleep duration than watching television, according to a study presented at the American Psychiatric Association Annual Meeting.

Researchers analyzed data about media usage and physical activity from the 2009 Youth Risk Behavioral Survey maintained by the Centers for Disease Control and Prevention. The researchers found different types of media exposure have different impact on self-reported teen sleep patterns. Gaming and Internet usage negatively impacted reported sleep time, while television had no impact, and physical activity improved sleep time.
