Normal sleep patterns and prevalence of sleep disorders in the general population are largely unknown. The aim of HypnoLaus is to record sleep, analyze sleep characteristics and determine the prevalence of sleep disorders in a large population-based sample, which has undergone comprehensive genetic, somatic and psychiatric investigations.

The HypnoLaus results combined with genetic, cardiovascular, metabolic and psychiatric data provide a unique opportunity to determine the interaction between sleep, its genetic determinants and cardiovascular, psychiatric or metabolic diseases.

6000 participants of the CoLaus study were invited to answer various sleep questionnaires regarding their sleep habits and potential sleep disorders. So far, a total of 2168 participants aged 40 to 80 years have agreed to have a full sleep study (polysomnography) at home. Recruitment of the volunteers started in April 2009.
