Children and teens need 8-10 hours of sleep a night. Adults typically need 7-10. Start and stick to a regular sleep schedule . This is extremely common in youth returning to school after summer or other breaks and is by far the main reason so many youth are drowsy, not alert, or falling asleep in class. No naps allowed .
Naps decrease the ability to fall asleep at night.
A nap makes you less likely to be tired at an optimal bedtime thereby causing sleep or sleepiness in the morning when you need to get up. Naps worsen Sleep Phase Disorder. Phase Disorder is adjusting the time you get up. If you can't get to sleep, get out of bed . They need to get up and do something else until they feel sleepy and only then go to bed.
