DEAR DOCTOR K: My teenage daughter stays up late, then has a hard time waking up for school. I don't think she's getting enough sleep. What can I do to help her fall asleep at a reasonable time?
DEAR READER: Not getting enough sleep can have serious consequences. This is especially true for children and adolescents, whose developing brains are very sensitive to insufficient sleep. Teens need as much sleep as do adults, maybe more. They need eight to 10 hours for optimal function, but studies have found that few get this much sleep.
