Inadequate sleep in children has been associated with an increased risk of injuries, high risk behaviors, drowsy driving, hypertension, obesity, and depression. On the other hand, children who get sufficient sleep every night demonstrate improved behavior, learning, attention, memory, emotional regulation, quality of life, and mental and physical health.
What does sufficient sleep look like? The AAP recommends children 6 to 12 years old sleep 9 to 12 hours every 24-hour period. Children 13 to 18 years old should regularly sleep 8 to 10 hours. When children are young, it’s a little easier to determine if they are sleeping enough. You know when they go to sleep and usually know when they wake up. But as they enter the school age years, parents lose a little bit of control over their children’s sleep patterns, and that can spell trouble.
Pediatricians Sound the Alarm
The National Survey of Children’s Health for 2016-2017 gave researchers the information they needed to associate adequate sleep with behavioral markers of flourishing in children. The survey asked parents and caregivers of 49,050 children aged 6 to 17 how long a randomly selected child in their care slept each night. It also asked questions about these children’s behaviors that demonstrated flourishing as defined by the survey authors.
These behaviors include:
- showing interest and curiosity in learning new things
- caring about doing well in school
- doing required homework
- working to finish tasks
- staying calm and in control when faced with a challenge
The study’s authors then analyzed these responses to determine the effect of sleep on children’s behavior and ability to flourish. Here’s what the researchers found.
Only 47.6% of the 49,050 children identified in the survey regularly slept at least 9 hours on an average weeknight. Compared to children who did not get adequate sleep each night, the nearly 48% who were well-rested were
- 44% more likely to show interest and curiosity in learning new things
- 33% more likely to do all required homework
- 28% more inclined to care about doing well in school
- 14% more likely to complete tasks
In summary, the study’s abstract author, Dr. Hoi See Tsao, concluded that children who regularly sleep nine or more hours per night are more likely “to demonstrate measures of childhood flourishing in comparison to children with insufficient sleep.”
Barriers to Sleep for Children
The survey did not reveal what was keeping these children awake longer than is healthy for them. But researchers have identified several risk factors associated with unhealthy sleep duration in children including
- lower levels of parental or caregiver education
- children living in families whose income is lower than the federal poverty level
- increased usage of digital media
- increased number of adverse childhood experiences
- presence of mental health issues in children or their caregivers
Dr. Tsao recommends helping children get the sleep they need by
- limiting digital media usage and restricting it at least an hour before bedtime
- establishing and maintaining soothing bedtime routines
- appealing to school districts to control the ever-lengthening school day
- encouraging school districts to delay school start times for teenagers
