Analysis of bedtimes at 3, 5, and 7 years old of more than 11,000 children living in the U.K. revealed irregular betimes impact cognitive development. Not having a regular bedtime at age three was associated with lower cognitive scores at age 7 for both boys and girls. Not going to bed at the same time each night at multiple ages was associated with the greatest impact on cognition. This was found to be independent of stressful family environments.
PositiveTip: It might seem insignificant, but regular bedtimes support optimal cognitive development in children.
