Abstract
Abstract: Physicians recommend a high water intake to prevent
cerebral infarction by decreasing blood viscosity. However, there is
no evidence that high water intake decreases viscosity, although it
increases urinary frequency. Therefore, we investigated the change of
blood viscosity and urinary frequency by high water intake. We
examined the change of blood viscosity after acute water intake, the
circadian rhythm of blood viscosity, and the change of early morning
blood viscosity and urinary frequency after high water intake for 1
week in healthy volunteers aged 31-75 years. Blood viscosity decreased
transiently by acute water intake, but remained within the range of
its circadian rhythm. Morning blood viscosity did not alter by high
water intake for 1 week, although urinary frequency increased. Because
excessive water intake increases urinary frequency without decreasing
blood viscosity, a high water intake should not be recommended in
persons with urinary frequency.

Good find!

As an anecdotal addendum to this, physical trainers have fairly recently
come to recognize that distance runners may over-hydrate during long
runs (particularly marathons or longer), thus inducing hyponatremia with
sometimes serious results. They are beginning to advise caution about
the rote runner's advice to drink fluids at every opportunity during a
run.
