If you have not already done so, please read Blog Posts 1 through 5 that describe how sleep is important and beneficial. I will post specific information for parents and children based on my book, “Healthy Sleep Habits, Happy Child.” Please do not be put off by my book’s length. This is a reference book. Read only the topic of interest to you.
I reviewed the literature to answer this question and found 35 relevant published studies. Here are my conclusions with some examples of the studies.
The shorter the night sleep duration, the more mental health problems occurred. Also, this study showed that measurements of emotional and behavioral problems at baseline did not predict sleep durations 15 months later. Additionally, this study suggests that when parents help their children sleep better it might prevent the development of mental health problems because: Compared with children who decreased or had no change in night sleep duration over the 15-month observation period, those children who increased their night sleep duration had a concurrent decrease in measurements of hyperactivity/inattention, conduct problems, better peer relationships, and more prosocial behaviors. This study suggests that when parents help their child sleep better future potential difficulties can be prevented.
The effect of nonregular bedtimes was cumulative-the more years of nonregular bedtimes, the worse the behavior. However, when children changed from nonregular to regular bedtimes, they showed improvements in their behavior. This study suggests that when parents help their child sleep better future potential behavioral difficulties can be prevented.
