Immersion diuresis is a condition where a person experiences an increase in urine volume due to immersion in water. There are a few synonyms for this condition that can be used to describe it, such as immersion diuretic effect, aquatic diuresis, or water-induced diuresis. These terms refer to the same phenomenon and describe the same increase in urine production. Immersion diuresis is not a harmful condition and is largely harmless, but it is important to be mindful of the amount of fluids lost during such activities. This is especially important if one partakes in water sports or activities where large amounts of water are consumed.
