Many children and adolescents with depression suffer from sleep problems such as insomnia or hypersomnia (excessive sleepiness) or both. According to recent research, children with depression who suffer from both insomnia and hypersomnia are more likely to have severe and longer-lasting depression. They are also more likely to suffer from weight loss, impaired movement, and anhedonia (an inability to feel pleasure). Additionally, NSF's 2006 Sleep in America poll, which focused on children aged 11 to 17, found a strong association between negative mood and sleep problems. Among adolescents who reported being unhappy, 73% reported not sleeping enough at night.
