Sleep disorders are amongst the most common medical complaints of the 21st century. Healthy sleep acts as a sensitive indicator of physical and mental health therefore it has a significant public health impact (Taylor et al., 2003, 2007). Insomnia is the most frequent sleep disorder. Approximately one third of the population are characterized with insomnia symptoms, amongst 10% of them as a chronic condition and the frequency is increasing with age (Ohayon, 1996; Nau, Lichstein, 2005; Hohagen, Rink, Kappler, 1993). According to a large-scale representative population survey (Hungarostudy, 2002) the point prevalence of insomnia is 9.2% in Hungary (Novak, Mucsi et al, 2004). Cognitive behaviour therapy is one of the most evidence-based treatment approach of insomnia, especially in chronic cases. According to both European (NICE) and US (AASM) guidelines CBT is recommended as first rank treatment (Schutte-Rodin, Broch et al, 2008; NIH Guideline, 2005; Perlis, Jungquist et al, 2005; Wang, Wang, Tsai, 2005; NICE Guidelines, 2004, Estivill, Bovéet al., 2003; Smith, Perlis, Par, 2002; Purebl, Bánki et al, 2010). Nevertheless, “classic” CBT techniques alone are not suitable enough for long-term success, the therapy ought to integrate counseling targeting the restoration of circadian rhythm and healthy, sleep-friendly lifestyle changes.
