A study from the National Sleep Foundation found an estimated 45% of adolescents in the US don’t get enough sleep and many suffer insomnia, reports the McPherson Sentinel.

According to a study performed by the National Sleep Foundation, an estimated 45 percent of adolescents in the United States do not obtain an adequate amount of sleep. It also concluded in 75 percent of those cases insomnia was to blame for the lack of rest. Another 31 percent of adolescents only receive what is considered a borderline acceptable amount of sleep. In addition, 20 to 30 percent of children younger than 5 suffer from some type of sleep disorder.

Insomnia is the inability to get to sleep or stay asleep and is commonly found in adults, but studies have shown an increase of the disorder in children. What causes insomnia can vary, especially when it comes to kids. In adults, a large contributing factor to insomnia is stress, but it’s hard to fathom that a child could have enough stressors to keep them awake at night. As it turns out, one in three suffers from chronic stress, and stress is still the number one cause of insomnia even in kids. Stress can manifest in many ways: too many obligations, high expectations, homework, dating and, to top it all off, stressing out about being able to sleep at night.
