Diuresis associated with prolonged water immersion

Duane E. Graveline, Margaret M. Jackson


Utilizing complete water immersion, compensated respiration, and unrestricted activity, the diuretic response of five human subjects to 6-hr periods in this environment was studied. The results indicate that the low specific gravity diuresis which occurs in this situation has characteristics of both a water and an osmotic diuresis. Possible physiologic mechanisms are discussed.
