So Dr. Michael Breus, a sleep expert from WebMD.com, visited The Early Show to offer advice on how to get your kids back on a healthy sleep schedule before the new school year begins.
Dr. Breus says, "Kids that are sleep deprived may be falling asleep on the ride to school in morning. They may be moody. Younger children actually tend to act a little rambunctious when they're sleep-deprived."
He notes smaller children ages 3 to 6 will need between 10 3/4 to 12 hours of sleep, including naps. Kids between 7 and 12 years may need 10 to 11 hours of sleep. And in the teenage years, from 12- 18 years, they need between 8 and 9 hours of sleep.
He says, "Sleep deprivation induces significant reductions in performance and alertness. Reducing your nighttime sleep by as little as one-and-a-half hours for just one night could result in a reduction of daytime alertness by as much as 32 percent.
"Even 20 fewer minutes of needed sleep may significantly affect behavior in many areas. One study showed that those students with Cs, Ds and Fs got about 25 fewer minutes of sleep and went to bed an average of 40 minutes later than A and B students. Research has shown that teens suffer lower self-esteem and more depression when they don't get enough sleep."
So here are some things parents can do before school starts:
Wake Your Kids Up Earlier - Get your kids to wake up earlier, rather than sending them to bed earlier. This works for kids who are in first grade and up, and is particularly helpful with teens. Do this in 15-minute increments. Each day wake them up 15 minutes earlier until they are at their school time wake-up time. After waking up your kids earlier, keep your kids active during the day. This will tire them out naturally, and then, you can start to slowly move them toward their normal bedtime.
Change Meal Times - Your body responds to food and sleep. Look at your summer meal times. They tend to be later than dinner times during the school year. They also tend to have sugar-filled snacks closer to bedtime. Start moving the meal times down by 15 minutes each day in order the get your kids used to a new time. Eliminate sugar snacks several hours before bedtime.
