| Research Abstract |
To evaluate the physiological differences of the male students between northern (Akita) and southern part (Fukuoka) in Japan, we measured several kinds of hormone in urine in summer and winter. Noradrenaline obtained from the students in Akita was significantly higher(p<.01) than that in Fukuoka in both summer and winter. Noradorenaline in winter was higher(p<.01) than that in summer in both areas. Cortisol or 17-OHCS in Akita was also higher than Fukuoka in both seasons. Noradorenaline is an index of sympathetic adrenal medullary (SAM) axis. Cortisol is an index of hypothalamic-pituitary-adrenal (HPA) axis. Those axis are activated with the stressor including environmental and emotional stress. Higher Noradorenaline and Cortisol in Akita may be effective to adapt to cold exposure.
