A new US study says that the time at which school
begins influences the number of road accidents involving teenagers, with fewer
accidents reported if school starts late. Teen drivers who begin with school
early in the morning are more prone to road accidents.
The study suggests, since early high school start
times may promote sleep loss and daytime sleepiness, students may not be so
alert. Starting school later in the morning might make young drivers more alert
because they get more sleep. Even an hour's delay improves attention levels and
performance. The study has shown that crash rates for teenagers who
started school at 7:20am were 41% higher than students who started class 1 hour
and 20 minutes later.
have shown that even 55minutes longer sleep enhances performance levels of
students in tests which require attention.
The study has been published in the Journal of Clinical Sleep Medicine.
