Is it possible to over hydrate?
Yes. If we over-hydrate, the water concentration of the blood increases, while the salt concentration is diluted, leading to a condition called hyponatremia. A sustained decrease in the blood’s sodium concentration alters osmotic balance, leading to an increased movement of water into the brain, which in turn leads to swelling. This can progress to confusion, seizure, coma, and even death in very extreme circumstances.
