“Because children’s brains are a work in progress until the age of 21, and because much of that work is done while a child is asleep, this lost hour appears to have an exponential impact on children that it simply doesn’t have on adults.” (Excerpted from page 31 of NurtureShock)
I was surprised to learn, as I read the second chapter of NurtureShock, by Po Bronson and Ashley Merryman, that it is a fact that children today – from elementary school through high school – get an hour less sleep each night than they did thirty years ago. I was also surprised to learn that even kindergarteners get 30 minutes less sleep each night these days. However, I was truly alarmed to learn about the lasting impact that this loss of only one hour can have on children. The reasons why children get one hour less of sleep each night vary and have much to do with family systems and the culture in which we now live. Many of us adults also get less sleep, but we muscle through it. If we can do it, so can our kids, right? Anyway, we can all catch up on the weekend … right? But what was alarming for me to learn was, the cost of less sleep is much greater for children than it is for adults. And “catching up” on the weekend doesn’t solve the problem. With more sophisticated techniques of brain study available to us now, sleep scientists have been able to measure the impact of this “single lost hour.” It isn’t just a matter of falling asleep in first period or being a little tired during after-school music lessons. Not only do academic performance and emotional stability suffer but also things that seem unrelated, such as an increase in obesity, ADHD, and childhood depression. Some scientists are concerned that sleep deprivation in children can lead to permanent changes in a child’s brain structure. As a parent and an early learning professional, these are the words that alarmed me the most. I look forward to a lively discussion on Chapter 2, “The Lost Hour,” in NurtureShock, and I hope you will join us.
