Why You Might Not Really Need 8 Glasses of Water Per Day?
Why You Might Not Really Need 8 Glasses of Water Per Day?
Exercising can increase your need to drink water, but don't overdo it.
As spring unfolds, hydration challenges take root across schools, sports and workplaces. These heavily marketed hydration challenges serve to cultivate both camaraderie and friendly competition to ensure that we drink compulsory amounts of water throughout the day.
Hydration and "Gallon Challenges" support the widely held belief that water consumption beyond physiological need -- or thirst -- is healthy.
But this is not so. Individual body water needs -- intake -- are primarily based upon how much water people lose. How much water each person needs to drink mainly depends on three factors:
Body weight. Bigger people need more water.
Environmental temperature. When it's hotter, people sweat and lose water.
Physical activity levels. Increased exercise intensity increases sweat water losses.
Therefore, a "one size fits all" fluid replacement strategy, such as drinking eight glasses of eight ounces of water per day, is inappropriate for everyone.
