If your child has frequent health and/or emotional problems, consider that a lack of sleep may be all or at least part of the problem.
Every function in the body is affected by sleep. And for a child, the risks of sleep deprivation are much more serious than simply waking up in a grumpy mood. Research shows that children with sleep disturbances have more medical problems-such as allergies, ear infections, and hearing problems. They are also more likely to have social and emotional problems.
There is a whole host of health problems that have consistently been associated with inadequate sleep.
Sleep loss is linked to obesity and diabetes.
Sleep loss can contribute to weight gain and obesity by triggering the hormones that regulate appetite and hunger. In other words, inadequate sleep may cause children to overeat. University of Chicago researchers reported new evidence in December 2004, Annals of Internal Medicine, that a lack of sleep changes the circulating levels of the hormones that regulate hunger, boosting appetite and a person's preference for high-calorie, high-carbohydrate foods.
Many physicians believe that sleep loss can also affect the ability to metabolize sugar and trigger insulin resistance, a well-known factor for diabetes. At the American Diabetes Association's 61st Annual Scientific Session, new evidence was presented that inadequate sleep may prompt development of insulin-resistance, a well-known risk factor for diabetes. (In recent years, there has been a dramatic rise in the incidence of childhood obesity as well as type 2 diabetes.)
Sleep loss is associated with anxiety and depression.
Insomnia is a significant risk factor for depression. It also contributes to anxiety by raising corstisol, the stress hormone. We have known for some time that depression and anxiety can contribute to insomnia; however, recent research has shown that insomnia often precedes the first episode of depression or of a relapse. Physicians are looking more closely at the importance of solving sleep problems in order to eliminate or decrease the severity of anxiety or emerging depression.
Sleep loss may impede physical development.
The highest levels of growth hormone are released into the bloodstream during deep sleep. Because sleep deprivation results in a decrease in the release of growth hormone, height and growth may be affected by a lack of sleep.
Sleep loss affects immunity.
During sleep, interleukin-1, an immune boosting substance, is released. Several
nights of poor rest can hamper a child's immunity.
Sleep deprived children are more accident prone.
A lack of sleep has an adverse affect on motor skills. Dr. Carl Hunt, director of National Center on Sleep Disorders Research at the National Institute of Health says, "A tired child is an accident waiting to happen." Bicycle injuries and accidents on playground equipment are more likely to occur when a child is sleep deprived. And unfortunately, the stakes get continually higher when poor sleeping habits continue and the accident prone child becomes the teenager who is driving while drowsy.
Sleep loss may affect the response to vaccinations.
A study published in the Journal of American Medical Association (September 25, 2002) reported that sleep deprivation limited the effectiveness of the flu shot.
