Can a person drink too much water in a day and how much is too much?
Hyponatremia is caused by an excessive amount of water in the blood system, causing the relative level of sodium to drop drastically and forcing the cells of the body to gorge in water. That's a cause for mayhem.
However, bear in mind that the average human kidneys can process through 5.3 to 7.4 Gallons of the life-giving and healing crystal fluid, say 20 to 28 liters.
The rest depends on, the time of the day, the weather, your level of physical activity, your diet, meal schedules, and overall health. In addition, course how you are pacing your hydration.
