Slide 7:Sleep is Regulated by a Biological Clock in the Brain The internal mechanism that regulates when we feel sleepy and when we feel alert Resides in the brain and is affected by light and dark Retin0-hypothalamic tract Suprachiasmatic nuclei Hypothalamus

Teens are Chronically Sleep Deprived :Teens are Chronically Sleep Deprived Teens need 8 ½ –9 ½ hours of sleep. 85% get less than the minimum requirement. Teens often have poor sleep habits and irregular sleep patterns – trying to make up for sleep on weekends. Teens regularly experience daytime sleepiness.


Teens Experience a Shift to a Later Sleep-Wake Cycle :Teens Experience a Shift to a Later Sleep-Wake Cycle The biological clocks of children shift during adolescence, which drives them to a later bed time schedule (around 11:00 pm) and a natural tendency to wake later in the morning. This delayed phase syndrome can place them in conflict with their schedules – particularly early school start times.


Delayed Sleep Phase Sleep Schedule :Delayed Sleep Phase Sleep Schedule In order to get to school on time, many teens must wake before 6:30 am and shorten their sleep time.

Advocacy Issue: SCHOOL START TIMES :Advocacy Issue: SCHOOL START TIMES High school and middle school start times tend to be early - interrupting adolescents’ sleep patterns - and making it difficult to wake up and be alert: > particularly in the morning; and > often living with the consequences of sleep deprivation throughout the day.


Advocacy Issue: SLEEP CURRICULUM :Advocacy Issue: SLEEP CURRICULUM Educators, parents, many health care providers and others receive little training about the physiology and importance of sleep. Very few schools offer sleep information to their students or include it in health or science curriculum.


Helping Schools Become Sleep-Friendly :Helping Schools Become Sleep-Friendly Many schools across the country are establishing later start times to get in sync with a teen’s sleep schedule NSF has developed a national initiative and sleep for TEENS toolkit Several studies cite the positive outcomes of “sleep-friendly” school start time policies


Positive Outcomes from Minnesota Schools :Positive Outcomes from Minnesota Schools Teachers report more alert students. Students report less sleepiness and better grades Fewer students seeking help from school counselors or nurses Parents report more “connect time” and teens easier to live with Tardiness and sick days declining


Recent Longitudinal Study of Minneapolis Public Schools :Recent Longitudinal Study of Minneapolis Public Schools Students sleep, on average, one hour more They do not stay up later and get 5 more hours of sleep per week compared to students at schools with earlier start times.


What YOU CAN DO… in your Community :What YOU CAN DO… in your Community Present this important information to your parents, teachers, local school board and community groups.
