Are You Drinking Enough Water?

We all know we’re supposed to drink plenty of water, but how much is enough? Various studies have been conducted on the question, but the only consensus has been that water is vital to normal function. Our bodies, on average, are composed of around 60% water, making it the most abundant chemical of the human body.  Water is vital to virtually all of our bodily functions, making it critical to replace the water lost every day.  On average, we lose about 1.5 liters of water per day from urine output, as well as another liter from breathing, sweating, and other bodily functions. 

            One theory of how much water we should drink comes directly from this calculation.  The idea is to replace the water that we lose, approximately a liter and a half.  Another approach to this idea is the general rule of drinking eight 8-ounce glasses of water per day.  This is sometimes referred to as the 8x8 rule.  Still another idea is to follow daily recommended values for water.  These values are about 3 liters per day for men and about 2.2 liters per day for women.  This amounts to about 13 cups per day for men and about 9 cups per day for women.

            Of course, the amounts for all of these explanations are adjusted based on various factors, such as activity level, climate, health conditions or illness, and pregnancy.  For exercise lasting 20-30 minutes, an extra cup or two of water is necessary to replace fluid from sweating.  For longer exercise programs, especially those lasting over an hour, more fluid is needed.  Drinks with sodium and potassium are recommended, as these electrolytes are also lost in great numbers during extended periods of exercise.  Drinks such as Gatorade, Powerade, Vitamin Water, or any other drink containing electrolytes will do.

            In warmer climates or in altitudes of over 8,000 feet, additional fluids are necessary.  Pregnant women will also have an increased demand for fluids, as well as those with a cold or flu.  Symptoms such as diarrhea, vomiting, and fever will increase the body’s need for water as well. 

            Though water is usually the best choice for staying hydrated, other fluids will do as well.  Sports drinks and juice will count towards the daily water intake, as well as soda and coffee.  Even beer and wine will count, though these should not be used as replacements for water. 

            Waiting until you’re thirsty to drink water may not be the best way to keep hydrated.  In fact, your body’s signal that you are thirsty is already a sign that you are dehydrated.  The best way to stay hydrated is by drinking a cup of water with each meal, as well as a cup in between in each meal. 

            A good way to judge whether or not you are getting enough water is to pay attention to your urine.  A healthy person’s urine is clear or light yellow.  If you’d like more help on getting the proper amount of fluids in your diet, you can talk to your doctor or a certified dietician.
