<abstract>The aim of this is to verify a hypothesis that critical flicker fusion frequency (CFFF) is season-related because of changes in the intensity and duration of sunlight. CFFF has a wide application in different fields, generally as an indicator of human workload. Therefore, confirmation of previous observations that CFFF is subjecto to a seasonal rhythm could make theoretical as well as practical sense</abstract>
