摘要

Melatonin is a major hormone of pineal gland. It is responsible for diumal and seasonal biological cycles. Local geographical factors (depended on latitude), like a midday Sun altitude and day length in connection with climate conditions (cloudiness, solar radiation etc.) directly affect regional differences in melatonin rhythm. The smallest values of melatonin secretion was noted during the day time and in Winter. At Spring and Summer the biggest values were observed for Polish participants, in Autumn and Winter for the Japanese. From Spring to Autumn in Poland maximum melatonin secretion was over 50 pg/ml, at Winter only 20 pg/ml. Time Peak was noted between 2 and 3 a.m. at Polish subjects, at Japanese between 3 and 5 a.m. and at Vietnamese between 4 and 6 a.m.
