520 3# ‡aExamines cold-induced effects on pineal and thyroid hormones, as well as associations of these hormones with psychological performance; and determines how psychological performance could be affected by demographic, anthropometric, physiological or biochemical measures during cold acclimatisation. Examines feasibility of urinary melatonin (MT) rather than 6-sulphatoxymelatonin (aMT6s) as indicator of MT secretion. Includes field study of associations of mood and cognition with demographic, anthropometric, physiological and biochemical measures as determined in healthy, euthyroid subjects in Antarctica in beginning and at end of summer and winter seasons. Results indicate that associations of serum MT, thyrotropin and thyroid hormone levels with mood and cognition are consistent with psychological changes associated with onset and consequent stages of polar T₃ syndrome. In Antarctic field study at McMurdo and South Pole stations cognition and mood were associated with subject's age and gender, which seemed to affect physiological changes during acclimatisation to cold and darkness.
