Negative Effect of Sleep Deprivation on a Child's Performance

Airan is interested in investigating the social and health issue in Asia. Airan also doing research on effect of sleep disorder to health.

1) Increases children’s injury risks

According to a study published in Pediatrics, children who sleep fewer than 10 hours a day have an 86 percent higher risk of injury than those who sleep more than 10 hours a day.

The most common types of injuries were falls (42.5%), knocks against objects (16.4%), and sprains. Cycling mishaps (13.4 percent).

According to the report, the majority of the kids weren't doing anything particularly risky. However, the night before, many had slept fewer than 10 hours or had skipped their naps.

Children who have been up for at least 8 hours without sleep or a nap are four times more likely to have an injury, according to the study. Boys were exposed to 5 times the danger, while females were exposed to double the danger.

2) Affects School Performance

Sleep deprivation can contribute to poor academic performance. In a poll of over 3000 high school students conducted by two psychologists, those who received Cs, Ds, and Fs got around 25 minutes less sleep and went to bed approximately 40 minutes later than those who had As and Bs. In addition to harming academic performance, insufficient sleep may be disruptive to teenagers and children in other ways.

Students in their twenties are among the most sleep-deprived. In the United States, 30% of adolescent students fall asleep in class at least once a week. The normal adolescent needs roughly 9 hours of sleep (experts recommend 10 hours), yet in the United States today, many kids sleep fewer than 7 hours.

As a result, many teenagers are sleepy during the day. If these students had slept for 9 hours instead of 7 hours a night, they would have spent around 137 days in health-giving and brain-boosting dreamland over the course of a normal year.

However, because the average adolescent slept for just 7 hours, he or she missed almost 30 crucial days of sleep that year. Inadequate sleep causes people to grow tired in class, impairing their focus. Their school grades drop as a result of their inattention.

These teens also undergo mood and motivation shifts, which can worsen behavioral and emotional issues.

3) Different Circadian Rhythms

According to a sleep expert, while the rest of us operate on a 24-hour cycle or circadian rhythm, the typical teenager's internal clock runs much slower, on a cycle of 26-30 hours. It's pointless to advise them to go to bed at 11 p.m. when their internal clock shows it's just 8 p.m.

Their body tells them it's 4 a.m. when the alarm goes off at 7 a.m. They drag themselves to school, groggy from lack of sleep. Although school is specially designed to satisfy their learning requirements, the timetable is designed for the convenience of adults.

Some schools in the area that have experimented with later starting hours have discovered that pupils are more interested and attentive. High schools in Minnesota have tried starting classes at 8.30 a.m., which is only one hour late.

According to the findings of this trial, kids' grades improved while discipline issues decreased. Montgomery County, Maryland, agreed in 1998 to provide high school students the option of starting at 7.25 or 9.15 a.m. Similar methods are being investigated by other school districts around the United States.

According to one poll, teenagers who obtain fewer than 6.5 hours of sleep per school night or report a 2-hour discrepancy between school night and weekend bedtimes had greater complaints about low mood than adolescents who receive more sleep.

Adolescents with little sleep also have less control over their emotional responses. A sleep-deprived adolescent, for example, is more prone to getting angry or violent when confronted with a difficult job.

Action Overseas

The problem of sleep deprivation among teens is so bad that legislation has been presented in the United States Congress to urge schools to adopt later start times while also shortening the school day. A federal subsidy is included in the law to assist offset administrative and operating costs connected with modifying school hours.


Sleep deprivation can occasionally resemble or increase ADHD (Concentration Deficit or Hyperactivity Disorder) symptoms such as distractibility, impulsivity, and problems keeping attention. In fact, ADHD symptoms are more common in youngsters who have sleep problems.

These sentiments, along with a sense of loss of control, explain why sleep deprivation is frequently employed as a form of torture. Continuous interruption of sleep, for example, is thought to be one of the most effective methods of "softening up" convicts.

Sleep disturbance is also sometimes employed on purpose to generate false confessions. Torture victims frequently begin to believe that the false claims they make are genuinely real if they are subjected to it for a long enough period of time.

According to the results of Amnesty International, 54 percent of torture victims interviewed reported being deprived of sleep for 24 hours or longer. In half of those cases, sleep deprivation might have lasted more than a week. In those with a history of mental issues, a lack of sleep may potentially induce psychotic-like symptoms.
