Drinking too much water in a short period of time can cause brain swelling, warned emergency room physician Eugene Wortsman.

Water intoxication, or hyperhydria, he explained, is possible when the body receives more water than it can process — that is, more than a liter per hour. If you drink a lot of water too quickly, he continued, the body stops functioning normally - the balance of electrolytes is disturbed. "The way salt, potassium, and calcium work in the body affects the work of nerves, muscles, and the brain. If the salt level is drastically reduced, hyponatremia leads to dysfunction of this," he said.

In the worst-case scenario, Wortsman continued, the body throws excess water into brain tissue. "Swelling of the brain, dropsy begins. The brain swells, and there's not much room in the skull for swelling, and things can get very bad quickly," he said.

The early symptoms of water poisoning, Wortsman clarified, are nausea, vomiting, convulsions, weakness, clouding of consciousness, which can cause double vision in a person's eyes. The doctor advised drinking water little by little during the day - 2,5 liters for women and 3,5 liters for men.
