Group/Cohort Intervention/treatment
Blood samples will be taken for measuring copeptin levels in healthy subjects.
Other: observation
blood sampling during 24 hours

Primary Outcome Measures :
  1. measurement of copeptin values in mmol/l within 24 hours to assess the amount of release in a day curve. [ Time Frame: 24 hours ]
    The primary outcome measure is to compare the copeptin concentration in the early afternoon and the early morning by blood sampling at different time points. Evaluation of the question if there is a circadian rhythm in the copeptin release.
