[Treatment recommendations for chronic insomnia - cognitive behavioural therapy as first-line treatment].

Introduction: In addition to the treatment recommendations published by the Special Interest Group (SIG) "Mental Health" (formerly "Sleep Psychiatry") of the Swiss Society for Sleep Research, Sleep Medicine and Chronobiology (SGSSC), the following article focusses on cognitive behavioural therapy for insomnia (CBT-I), its evidence, implementation and application, including in shift work, patients on medication, older people, various formats and non-pharmacological alternatives. Chronic insomnia is a disorder characterised by hyperarousal rather than sleep deprivation. The most effective treatment is bedtime restriction. This can be accompanied by increased daytime sleepiness and concentration deficits, which can be challenging. Furthermore, it is a challenge to find activities for the time that becomes available. The number of therapy places is still insufficient. However, it has been shown that CBT-I is also effective in shortened formats, digitally or when carried out by other professional groups.
