Submitted by LCDR Elaine Little, USPHS | ||||||||||||||||||||
Drinking Water Week is the first week of May. May represents the beginning of the warm months ahead and should serve as a reminder to drink more water! We can survive a month without food, but only about a week without water. Why? This is because water is essential to your body with almost every part of the body cell, tissue, and organ needing water to function. Without enough water, dehydration, ranging from mild to severe forms, can set in. | ||||||||||||||||||||
Why is hydration
so important?
The following quote is taken from the Water Prayer in the “Mohawk Thanksgiving Address.” It reads:

Why do we need to
stay hydrated?
There are some physical and lifestyle factors that make it more difficult to maintain adequate fluid balance and may give rise to chronic and mild forms of dehydration. These include: poor thirst mechanism; dissatisfaction with the taste of water; consumption of the natural diuretics such as caffeine and alcohol; participation in physical activity; and environmental conditions. Many health experts agree that it is important for people to drink at least 8 cups of water each day, but may require more for adequate hydration. The average sedentary adult man must consume at least 2,900 mL (12 c) fluid per day, and the average sedentary adult woman at least 2,200 mL (9 c) fluid per day, in the form of non-caffeinated, nonalcoholic beverages, soups, and foods (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9972188&dopt=Abstract). |

What about hunger and thirst? Is it true that
thirst can often be mistaken for hunger?
Yes. This is why many weight loss experts recommend drinking a glass of water before eating a meal or snack. If that satisfies you, then it was thirst. According to ADA, “recognizing “real” hunger for many people sends them searching for food, often before they need to eat. Feeling hungry at the start of a meal is good, but knowing when you could wait longer is also important.” You may want ask yourself some of these basic questions before your next meal to help you better differentiate between hunger and thirst?
Thirst is clearly different from hunger. It is important to pay close attention to your surroundings and the environmental conditions. In dry climates, sweat evaporates rapidly and you may not notice that you are losing a lot of water and electrolytes, not to mention the physical work involved, all of which can contribute to dehydration. You may need to drink more than eight 8-ounce glasses every day especially if you spend lots of time outside. Below are some practical suggestions to consider when it comes to fluid management:

Water and/or fluid requirements increases with a person’s body size as does calories. The larger the individual, the more fluid is required to keep one from getting dehydrated.
