BIRMINGHAM, Ala. (WIAT) — Most children have a set bedtime when they’re growing up.
Parents, for the most part, are usually strict about keeping that schedule.
According to new research, parents have good reason to be strict with their children’s sleep schedule.
Research found that a consistent bed time may be linked to better performance on intellectual tests.
The researchers looked at information about bedtimes and standardized test scores for more than 11,000 children.
The study looked at children at ages three, five and seven.
Going to bed late didn’t affect a child’s development, but irregular bedtimes were linked to poorer developmental scores.
Researchers note the study is not proof that irregular sleep is a direct cause of lower test scores, though.
