Science behind teen sleep patterns
- Later sleep patterns are biological, not necessarily behavioral
- 9 or more hours of sleep is best for teenagers
- However, 69% of high school students do not receive 8 hours of sleep
- Delayed onset of melatonin (a chemical in the brain that regulates sleep) for teens makes it difficult to go to sleep earlier
- Melatonin release and natural sleep cycle begins between 10:45 – 11 p.m.
- Later school start times show no impact on when teens fall asleep.
