[Insomnia and Hypersomnia among Children and Adolescents with Psychiatric Disorders].

Insomnia and Hypersomnia among Children and Adolescents with Psychiatric Disorders The common symptom of sleep disorders is non-restorative sleep, which results in daytime sleepiness. Therefore in clinical practice simultaneous complaints of "not enough" and "too much" sleep are very frequent. For the investigation and treatment of organic sleep disorders, available instruments, guidelines and specialised institutions (sleep centres or sleep laboratories) are more advanced than for non-organic sleep disorders.

Increased slow wave sleep and reduced stage 2 sleep in children depending on exercise intensity.

Background: There is controversy about the consequences of physical exercise on human sleeping behaviors. Evidence suggests that voluntary physical exercise affects brain structures and functions. However, there are inconsistent data regarding the effects of exercise on sleep architecture and sleep continuity, especially the amounts of slow wave sleep (SWS) and rapid eye movement (REM) sleep.
