Why is this a problem?.......◦ Studies of the three mile island nuclear reactor
meltdown, and the NASA challenge space shuttle accident indicate lost sleep as a contributing cause of car accidents
Lack of sleep!!

School age children need between 9-10 hours sleep/night
For each of the past 3 decades, children have lost ½ hour of sleep ( today’s children sleep an average of 90 mins less each night)
Children’s sleep is different from adults; children spend much more time in rapid eye movement ( REM), which is the dream stage of the sleep cycle
Infants who typically sleep up to 16 hours/day, spend half of that is REM sleep
How Lack of Sleep affects children...

REM sleep is crucial for brain activity; the brain is at least as active during the dream cycle as it is when a person is awake
This activity is related to neural plasticity ( the growth and change of brain cells) which occurs during REM sleep
REM sleep allows children to process information that they have encountered during the day
Because the length of the REM cycle increases as the night wears on, a shortened night of sleep means less time spent in REM sleep

Children 10-14 years of age were limited in their sleep to 5 hours/night
The next day both their abstract thinking and creativity ( as measured by standardized test) had decreased temporarily
USA Study:

For children 9-12 years old, reducing the child’s sleep by a single hour negatively affected his memory and reaction time on standardized tests
Israel Study:

If sleep deprivation happens frequently, the important brain development that needs to take place during childhood simply cannot happen
![Page 9: Why is this a problem?....... ◦ Studies of the three mile island nuclear reactor meltdown, and the NASA challenge space shuttle accident indicate lost](https://reader036.vdocuments.us/reader036/viewer/2022083009/5697c0311a28abf838cdb095/html5/thumbnails/9.jpg)
Today’s teens are thought to be the most sleep deprived among children because their sleep need is 9 hours/night, but they rarely get that.
Canada study ( 2003): 75% of teens sleep fewer than 8.5 hours/night
Italy Study ( 2001): direct connection identified between risk of injury and children sleeping less than 10 hrs/night
![Page 10: Why is this a problem?....... ◦ Studies of the three mile island nuclear reactor meltdown, and the NASA challenge space shuttle accident indicate lost](https://reader036.vdocuments.us/reader036/viewer/2022083009/5697c0311a28abf838cdb095/html5/thumbnails/10.jpg)
Connection also identified between inadequate sleep and hyperactivity
Loss of sleep often shows up as hyperactivity because children are trying hard to stimulate themselves to stay awake
Infants with sleep problems in early childhood are more likely to be diagnosed with ADHD
USA study: survery of children 5-7 showed a high correlation between children who snored or had other sleep disturbances and those who had mild ADHD
Once sleep disturbances were eliminated, these children had noticeable increases in academic chievement

One main cause of poor sleep is childhood obesity
1 out of every 3 children, or 30% of American children are not regarded as clinically obese causing sleep apnea ( condition that causes people to temporarily stop breathing), hyperventilation, sleep disturbances
Other causes ( electronic diversions cause cognitive stimulation and engagement)
Vigorous exercising before bedtime Parents typically don’t recognize lack of sleep as a
serious health issue
