Study: Irregular bedtimes for kids affect test scores

July 10, 2013

Researchers looked at bedtimes and standardized test scores for more than 11,000 children.

They noted that going to bed late did not affect a child's development, but irregular bedtimes were linked to poor scores.

Researchers caution the study simply draws a correlation and is not proof that irregular sleep is a direct driver of lower test scores.

The study is published in the Journal of Epidemiology and Community Health.
