摘要

A 30-min. Delay in arnhigh schooler's morning could mean the difference between productive learning and dozing through class.rnCountering concerns that later school start times would lead kids to stay up later the night before, a new study by researchers at Hasbro Children's Hospital found that when ninth-to-12th-graders started school at 8:30 a.m. instead of 8 a.m., they went to bed 18 min. earlier and slept an average of 45 min. more each school night.
