He said an inadequate amount of sleep can affect academic performance and mood. In teens, a lack of sleep can affect decision-making and driving ability. Lack of sleep can even be harmful to a child’s health.
“Chronic sleep deprivation has been linked to mental illness, learning and attention problems, driving accidents, weight gain, even heart disease,” Dr. Senthilvel said.
How much sleep does your child need each night? Dr. Senthilvel said that school-aged children (6-12) need 9-10 hours of sleep nightly. Adolescents need less sleep than children—seven to nine hours—but when they sleep can make a big difference.
“Nearly 30 percent of high school students report falling asleep in school at least once a week,” he said. “School starts early in the morning but adolescents biologically aren’t sleepy until later at night.”
The use of electronics can also add to your child’s inability to sleep. A recent study out of Spain found that pre-school and school-aged children who spend more time watching TV get less sleep.
Dr. Senthilvel said electronic devices, like television or cell phones, are a big problem also.
“In my practice, electronic devices are an even bigger problem than TV for kids, especially for teenagers,” Dr. Senthilvel explained. “I see patients weekly whose sleep problems are associated with too much screen time.”
According to Dr. Senthilvel, prolonged exposure to lights from electronic devices and television can affect melatonin release. Melatonin is a hormone that helps regulate sleep and wake cycles.
“I agree with the American Academy of Pediatrics recommendation that kids under 2 years avoid exposure to any media and that older children be limited to one-two hours of screen time a day,” Dr. Senthilvel said.
