Abstract:

At Sympathoadrenal activity was appraised in 10 healthy men over a 1O week period, beginning in summer and ending in autumn. Two overnight urine samples per subject per week were analyzed for norepinephrine. epinephrine. creatinine, and urea. Evidence of high sympathoadrenal activity was obtained in summer, with reversal in autumn. The different catecholamines were shown to relate either to weekly mean maximum temperature. to weekly mean solar radiation, or to both climatic factors. Catecholamine excretion also tended to vary inversely with urea excretion.
