This is one of the many studies
很多研究都尝试改变学校的上学时间
that looked at changes in school start times
这是其中一个研究
Danner and Phillips changed school start time
戴纳和飞利浦将肯塔基州
in a county of Kentucky by 1 hour
一个县的上学时间推后了一个小时
It resulted in increase in sleep about 30 minutes
结果使所有高中生

平均睡眠时间增加了30分钟
The proportion of students getting at least 8 hours in bed
睡眠时间至少8小时的高中生人数
increased from 35% to 50%

but driving accidents in 16 to 18 year olds in that county

Whereas the accident rates in 16 and 18 year olds

in the rest of the state increased 7% over the same period
