their behavior.

 The new school year is upon us. From bedtime battles to the misery of 
morning call, summertime sleep habits die hard. Late summer nights 
combined with early school start times, and the stresses of just being 
a kid, deprive our children of essential sleep. And sleep deprivation 
often wreaks havoc with health, academic performance, and behavior. It 
is an unrecognized epidemic. 
 
From elementary school through high school and beyond, a great many of 
our children are chronically sleep-deprived. With more than 1/3 of 
elementary school-age children having some kind of sleep problem and 
most adolescents not getting enough sleep, many will struggle to meet 
the barrage of new challenges, demands, and emotions of a new school 
year. 
 
It is not widely recognized and appreciated just how pervasive and 
critical quality sleep is for brain development and how it directly 
influences daytime functioning, performance, mood, and behavior. When 
was the last time your doctor asked about your child's sleep? Parents 
wouldn't think of letting their child skip meals or run into a busy 
street, but staying up late is very often of little concern. It 
shouldn't be. 
 
Sleep Affects How Your Child Thinks, Feels and Functions 
 
More and more research studies demonstrate that daytime sleepiness 
from chronic sleep deprivation and poor-quality sleep has significant 
affects on daytime behavior as well as concentration, attention, and 
mood. Even 20 fewer minutes of needed sleep may significantly affect 
behavior in many areas. One study showed that those students with C's, 
D's and F's got about 25 fewer minutes op sleep and went to bed an 
average of 40 minutes later than A and B students. The pediatric 
research findings are startling and alarming: 
 
Poor sleepers reported being significantly more depressed, without 
energy, tired, tense, moody, stressed, irritable, and less rested and 
alert than good sleepers. Interestingly and importantly, they were 
also more likely to have a negative self-image, which, in light of 
the above, is not surprising. 
Insufficient sleep has been associated with daytime fatigue, inability 
to concentrate in school, ADHD, a tendency to doze off in class, 
problematic behaviors, and lower levels of social skills. 
Persistent sleep problems have been associated with learning 
difficulties throughout the school years. 
Poor sleepers were more likely to display type A behavior patterns. 
Teenage insomnia has been related to anger, depression, difficulty 
with school adjustments, and stress. And studies suggest that insomnia 
often begins early in life and persists into adulthood. 
Sleep-disturbed elementary school-age children may have poorer coping 
behaviors and display more behavioral problems at home and in school. 
Several studies report that more total sleep, earlier bedtimes, and 
later weekday rise time are associated with better grades in school. 
Those with poor grades are more likely to sleep less, go to bed later, 
and have more irregular sleep/wake habits. 
 
From Elementary to High School, Sleep Problems Are Pervasive and 
Widespread 
 
You may be surprised to learn how prevalent sleep problems are. In 
studies of elementary school-age children, nearly 40% showed some 
kind of sleep problem, 15% exhibited bedtime resistance, and 10% had 
daytime sleepiness. Up to half of adolescents reported at least 
occasional difficulty falling or staying asleep, with up to 13% 
experiencing chronic and severe insomnia. Clearly, the sleep time 
most teenagers get is insufficient: the average is under 7 ½ hours, 
with only 15% sleeping 8 ½ hours or more on school nights and more 
than 25% typically sleeping 6 ½ hours or less. 
 Does My Child Have a Sleep Problem? Awareness Is Key 
 
Given the prevalence and enormous impact of sleep problems on daytime 
functioning, we should all regularly look at our own children to see 
if they are getting the sound sleep they deserve. For some it may be 
obvious, but for most of us it requires some education, investigation, 
and a keen, watchful eye. This is because few of us really know what 
normal, healthy sleep should be, plus there is a great deal of 
individual variation among children and at different ages. Sleep 
deprivation is also difficult to detect because sleep problems are 
masters of disguise, often masquerading in myriad manifestations. 
Consider that: 
 
Children rarely complain about sleep problems. A study of adolescents 
showed that very few sought help for their sleep, even though some 
considered their problems to be very severe. Another found that almost 
90% of adolescents say that they need more sleep, but how many parents 
have heard their child say, "You know, I think I am going to go to bed 
early tonight." 
Adolescent sleepiness is so prevalent that it almost seems normal. 
Though bedtimes get later and later, the biological need for sleep in 
adolescents does not decease with age. 
Parents may overestimate the amount of sleep their child gets because 
we may be unaware of when our child actually falls asleep, as well as 
night awakenings. Research has shown that medical conditions may cause 
or contribute to sleep problems even when overt medical symptoms seem 
well controlled. For example, asymptomatic children with asthma may 
have poor sleep and daytime fatigue. Allergies may cause respiratory 
distress when sleeping. In one study, almost 1/3 of the children in 
elementary school reported significant body pains during the night, 
of which parents were largely unaware. 
Sleep deprivation may present itself in many ways other than daytime 
sleepiness -- inattention, poor concentration, moodiness, behavioral 
problems, and poor academic performance and social skills, to name a 
few. Interestingly, poor sleepers were found not to be consistently 
more tired than good sleepers, and they were actually least tired in 
the evenings, when most good sleepers were tired. 
 
What Can I Do? Think Sleep! 
 
With so many hidden faces of sleep deprivation, you must be aware and 
"think sleep." As a parent, if you do not recognize the problem, it 
may well go unrecognized. You will also likely implement any remedies 
required. Early intervention is important, given the consequences and 
that children do not "grow out of" sleep problems; rather, the sleep 
problems of childhood tend to persist into adulthood. 
 
Talk with you child. Just taking the time to ask some of the right 
questions can go a long way. If there is a problem, discuss it and 
make a plan agreeable to all. Include detailed targeted behavior 
changes and rewards. 
 
With your child in school during the day and with after-school 
activities and part-time jobs for many, it is critical to talk with 
teachers, coaches, bosses, etc. to see if your child is exhibiting 
any signs of sleep deprivation. This may involve you taking some time 
to educate the educators. 
 
Teach your child good sleep habits, also known as "sleep hygiene." 
Establish sleep-healthy bedtimes, bedtime routines, habits, and 
diets. Identify and reduce as much daytime stress as possible. Limit 
TV and other "screen time" (computers, video games), especially at 
bedtime, and do not put a TV in your child's bedroom, as it has been 
shown to negatively affect sleep. 
 
As in everything in life, do your best to be consistent and ask for 
help. Do not hesitate to call your doctor or sleep specialist. It's 
too important not to.
