A Falling Drop of Water
Water is essential for all living things to continue life. BBC Health indicates that most humans don't actually get enough water and that we often rely on thirst as our only clue to consume. However, thirst usually indicates that the body has already started dehydrating, so it is important to drink fluids as often as possible. BBC Health also claims that without water, our bodies would cease to function in a matter of days, so getting the correct amount is of utmost importance.
How Much?
Dr. Batmanghelidj, a proponent of water consumption and author of "Your Body's Many Cries for Water," suggests that adults should drink eight to ten 8- to 12-ounce glasses of water per day. Colas, juices, milk, teas and lemonades do count toward the fluid consumption goal (its a myth that it can only be water), but can add extra benefits or pitfalls. For example, colas and juices can add more calories, but juices can also give you at least one serving of fruit. Teas, juices and colas often contain a large amount of sugar or caffeine, which should be ingested moderately.
Why Water?
While not a magic cure all, water does help those who are ill by replenishing fluids and keeps the body working correctly. About 50 to 70 percent of a human adult's total body weight is water, which must be constantly replenished to provide homeostasis. Water aids in digestion, moves wastes from the body, helps keep muscles moving and replaces fluid lost by sweat.
Make Adjustments
If you suffer from an illness that causes you to make less fluid (like Sjogren's Syndrome, for example), are more physically active or are spending a lot of time in the heat, it is important to increase your fluid intake. Most likely under these circumstances, you will notice an increased thirst anyway, and it is important to satisfy that craving.
Is This Water Safe?
The U.S. Environment Protection Agency estimates that 90 percent of Americans have access to clean water through their taps. Visit its website (see Resources) to make sure your water is safe to drink.
While bottled water is convenient to carry around, the containers produce waste. It is more environmentally friendly to either reuse the bottles (refill with water from the tap) or purchase a water bottle to refill. Carrying water or a beverage with you at all times will encourage you to drink.
