PHOENIX -- School is finally out for Arizona students and many kids will be staying up later and sleeping in.
That has repercussions for students when they go back to school in August.
"It does take a good solid week to get them back into their routine," said Diane Cyment, a fourth-grade teacher at Madison Simis Elementary School.
That lack of sleep may be more pronounced at the start of the school year. Madison Simis will be starting its day at 7:45 a.m. come August, a full hour earlier than previously.
"That's going to be a big challenge, for both students and teachers," said Cyment.
Valley Sleep Center president Lauri Leadley also said parents should try to maintain their children's sleep schedule during the summer.
"Sleep is the main center for restoring the body, so if the growing brain is being sleep deprived you obviously aren't going to learn," said Leadley.
"It's very important for parents to keep kids on the same schedule if possible."
