High school students lose sleep when daylight saving time springs forward

A study in the August issue of the Journal of Clinical Sleep Medicine shows that high school students lose sleep on school nights following the change to daylight saving time that occurs in March. Results show that average cumulative sleep loss on weeknights following the time change was 2 hours, 42 minutes, and students displayed increased sleepiness and a decline in psychomotor vigilance during school days after the time change.
