The brain is the organ most critically affected by severe overhydration (water intoxication), while the kidneys are the primary organs overworked attempting to process the excess fluid. Excessive water intake dilutes blood sodium (hyponatremia), causing water to move into cells, leading to brain swelling (cerebral edema), increased intracranial pressure, and potentially fatal neurological symptoms.

How long does it take for a glass of water to reach your bladder?

A glass of water can reach your bladder surprisingly fast, often within 10 to 60 minutes for a hydrated person with an empty stomach, as water rapidly enters the bloodstream and is filtered by the kidneys into urine. However, if you're dehydrated or have a full stomach, the process slows down, and it could take longer as your body absorbs it for other functions before sending the excess to the bladder.
