A: Exercise and Nutrition Scientist Kathleen Alleaume responds:
“Your daily water intake depends on your size, gender, environment (such as the weather) and the amount of exercise you do. In general, the body uses between 1–1.5 litres of water daily, which is why most people benefit from drinking an average of two litres (eight glasses) of water a day. Too much water is anything over four litres a day (except for athletes, or people in extreme heat).
You can drink too much water, but it’s rare. The most common effect of too much water in a short period of time is a critical drop in sodium (salt) in the blood – a condition called hyponatremia. Symptoms include headaches, blurred vision, cramps, swelling of the brain, coma and in extreme cases, death. If you’re not thirsty and your urine is pale yellow, you are probably getting enough water.”
