My mom, knowing I drink a 1-2 gallons of water a day, recently showed me an article in a health magazine that got me worried.
It basically talks about water intoxication, and how the body maintains a delicate balance of sodium and electrolytes in the fluid outside the cells. Drinking too much water at once upsets that balance, and prompts the cells to absorb the excess water. The excess water causes the cells to swell.
Normally this isn’t a problem, because most cells can accomodate this swelling, but brain cells are confined by the skull. It goes on to say that brain swelling causes most hyponatremia symptoms.
It doesn’t say how much water is too much, but it does recommend a daily “total water” intake of 2.7 liters.
Something to think about?
