New age-specific sleep recommendations for children issued

Children who don’t get adequate rest are at risk for health problems ranging from diabetes to depression, according to the American Academy of Sleep Medicine, which this week issued age-specific sleep recommendations.


“Recharging your brain is similar to turning your computer off and turning it back on,” said Beth Malow, M.D., M.S., Burry Professor of Cognitive Childhood Development, professor of Neurology and Pediatrics, Vanderbilt Kennedy Center Investigator and director of the Vanderbilt Sleep Disorders Division. “If you don’t have that recharge, it can be very devastating.”

Malow served on the academy’s 13-member committee that researched clinical studies to issue the consensus statement. The recommendations include:

  • Infants (4 months to 12 months) should sleep 12 to 16 hours a day, including naps.
  • Toddlers (1 to 2) should sleep 11 to 14 hours, including naps.
  • Children (3 to 5) should sleep 10 to 13 hours, including naps
  • Children (6 to 12) should sleep nine to 12 hours.
  • Teenagers (13 to 18) should sleep eight to 10 hours.

One recent study indicated that only 15 percent of teenagers were getting 8.5 hours of sleep per night, Malow said.

“Sleep in our society, whether it is for kids or adults, is still viewed to be one of those luxuries ­— something you don’t have to do, particularly for our school-age kids and teenagers,” Malow said. “They have too much to contend with — all the academic demands, trying to get their homework done, after-school activities and jobs. Then a lot of the schools start early, at 7:30 a.m.”

School schedules with early start times are out of sync with the circadian rhythms of teenagers, whose sleep patterns change at puberty, Malow said.

“Many teens have a delayed circadian rhythm where they go to bed late and they wake up late,” she said. “So the child who would normally go to bed at 9 o’clock at night is now not able to go to bed until 10 or 10:30 because they have shifted into this delayed sleep phase that goes with being a teenager.”

Later school start times at 8:30 a.m. have been shown to improve academic performance, behavior and attendance, said Malow.

Inadequate sleep increases the risk of accidents, injuries, hypertension, obesity, diabetes and depression, according to the consensus statement. Regularly sleeping fewer than the number of recommended hours is associated with attention, behavior and learning problems. The committee also found that among teenagers, insufficient sleep is associated with increased risk of self-harm, suicidal thoughts and suicide attempts.
