Exclusion criteria
Exclusion criteria: Exclusion criterion is the occurrence of a chronic somatic or psychiatric diseases as well as the occurrence of an itch-associated (skin-)disease during the last five years or in the present. It is especially paid attention to, that no histamine-intolerance is apparent in the subjects by explicitely asking whether the subjects ever had allergic reactions. In case there is only a small suspicion that the subject could suffer from a histamine-intolerance, he/she is excluded from study participation. Additionally, the current occurrence of moskito-bites as well as the use of a pacemaker leads to exclusion of the subjects.
