How Much Water Do We Need?

Drinking water is considered a healthy habit, but drinking  too much water can also lead to a condition called hyponatremia. This condition is where a person does not have enough sodium in the bodily fluids outside the cells.

People mostly at risk are people drinking too much plain water and those working in hot climates that causes excessive loss of sodium from the body through sweating. Sodium is important for maintaining blood pressure, and is required for nerves and muscles to work properly. When levels of sodium outside of the cells drop, water moves in these cells to maintain balance, therefore causing it to swell.

So how much water does a person really need?  Doctors recommend that a person should drink six to eight glasses a day, or roughly 2.5 to 3 liters of fluid combined with a healthy diet of foods containing high moisture content like fruits and vegetables.
