Sleep Deprivation, Behavior, and the Young




These days, sleep is often seen as an expendable resource. With so much work to do and limited time to accomplish tasks, going to sleep later and waking up earlier seems so natural. For some people, lack of sleep was used to prove toughness and stamina. It was common for physician trainees to boast (in some cases complain) about getting little sleep. However, studies showing suboptimal patient care when residents are sleep-deprived have resulted in shorter working hours and mandatory time off after a number of hours at work.

Some of the most vulnerable to sleep deprivation are adolescents. With the economy faltering, parents and families are under enormous pressure, and children are bearing more stress than they should. This time period is also awkward for adolescents, because they are branching out and trying to discover themselves. In addition, they compete academically to gain admission to prized universities and to win scholarships. This competition, at times, can be stifling. To achieve their goals, many adolescents are cutting back on sleep, sometimes significantly. The National Sleep Foundation’s Sleep in America poll found that more than three-fourths of teens between the ages of 13-18 go to bed at 11:00 pm or later on school nights. It is not uncommon for high school students to be found at coffee cafes drinking large cups of coffee or lattes into the night as they finish their projects or study for an AP (advanced placement) class. Energy drinks, and even caffeine tablets to keep awake are being consumed and are causing irregular sleep patterns.

Sleeping teensThe loss of sleep in adolescents is causing more than just increased daytime sleepiness and irregular sleep patterns. A study examining the influence of sleep patterns in adolescents (ages 11-14) revealed symptoms of depression and a decrease in self-esteem with chronic loss of sleep. Those with insomnia were more likely to develop major depression, abuse drugs, and have nicotine dependence. Sleep deprived adolescents also experience more anger, sadness, and fear. Most alarming, however, has been the suicidal behavior exhibited in this group.

It is well known that sleep deprivation can affect brain activity. Insomnia and serotonin, in particular, may be linked to depression and suicidal behavior. Serotonin is a neurotransmitter important in the regulation of the sleep-wake cycle and has been found in decreased concentrations in the brainstem of suicide victims. Loss of sleep or the disturbance of sleep can cause fluctuations in serotonin.

Although there have not been many large studies examining loss of sleep and its effects on adolescent behavior, the effects of sleep deprivation in general have been well documented. Some of these effects include reduced short-term memory and learning ability, negative mood, inconsistent performance, poor productivity and loss of some forms of behavioral control. It is important for youth to have the proper amount of sleep. Doctors recommend at east 8 to 9 hours of sleep for teenagers.

    Links (between insomnia and other ‘problems’) are NOT causal correlates, they are statistical associations. Furthermore: these scare tactics only profit the medical-pharmacological community. They have elevated insomnia to an epidemic disease and completely drowned out the age-old wisdom that bad sleeping is a symptom of a life-lived-riskily. Just as sleep-clinics have little to do with helping your insomnia – they are sleep-apnea/mask fitting centers – so has medical insomnia-intervention nothing to do with the causes of bad sleep. You pay a high price – in more ways than one- to shoot the messenger.

    Sleep deprivation is a common lack of the required amount of sleep. This may arise as a result of sleep disorders. Now most of the peoples are facing this kind of problem. Sleep is as important to the human body as food and water. Use relaxation techniques to help you fall asleep quickly. Purposefully go to bed earlier each night. Don’t smoke or drink alcoholic or caffeinated beverages in the hours before bedtime. Improve your sleeping environment in any way you can.

    Sleep deprivation when I were a teenager was less down to insomnia and more down to being forced to go to school in the day time, despising school with every fiber of my being and feeling that the night time when I wasn’t in school was the only time that was mine and that as soon as I went to bed I’d wake up to another horrible miserable day of school.

    I think most teenagers who don’t sleep can, it’s just… if they go to sleep then they’ll only have to get up for school!
