Dr. Gellner: We all know that not getting enough sleep can make our kids cranky, but what other problems can it cause? I'll discuss a few of those on today's Scope. I'm Dr. Cindy Gellner.
Announcer: Keep your kids healthy and happy. You are now entering the Healthy Kids Zone with Dr. Cindy Gellner on The Scope.
Dr. Gellner: There are a lot of reasons why kids aren't getting enough sleep these days -- staying up late to watch TV or play video games, being on social media till all hours of the night, needing to stay up to finish homework or do extracurricular activities. This isn't a good thing though. For one, not getting enough sleep can actually affect a child's immune system by decreasing the cells which help us fight infections and increasing the cells that create inflammation.
Your child's body won't be able to respond to colds or bacterial infections as easily as they could if they get a cold. It will be harder for the body's immune system to get rid of any infection. When a child sleeps, they get better fever response. This is why fevers seem to be higher at night. Fevers are one sign that the body is trying to fight off an infection. And if a child is sleep-deprived, their fever reaction isn't primed and they can't fight off an infection as good as they could if they were well rested.
Lack of sleep can also have a negative effect on how a child learns. Overtired kids work more slowly because it's hard for them to remember what the teacher just told them or what they just read. Their brains have a harder time focusing, even interfering with the formation and recall of long-term memories. When kids are sleep-deprived their brains actually lapse into sleep-like brainwave patterns, which is why tired kids space out during class.
They're more distracted, they may make more careless errors, and they have a hard time focusing on class assignments and tests. And don't forget how kids become moody and impulsive when they're tired. They're more likely to lose their temper causing them to make poor choices and then sit in the principal's office rather than the classroom.
Finally, with childhood obesity being a major concern in society right now, we're finding that kids who sleep less than they should also are more likely to be overweight. This has to do with hormone levels and their effect on hunger. Tired children may tend to eat more because of an increase in the hormone that causes hunger and a decrease in the hormone which reduces hunger.
So when your child argues with you about staying up late, especially on a school night, remember these things and they will help you stand your ground and send them to bed at a reasonable time to get good sleep. If your child has a medical problem which prevents them from getting restful sleep, then it's time to schedule an appointment to discuss these concerns with your child's pediatrician.
