have most likely heard that our bodies are not capable of lasting more
than two to three days without water, though that you would be capable
of going weeks without food. Water is required for very basic
physiologic functions such as regulating blood pressure and body
temperature, hydration and digestion (the body requires about 1.5
milliliters of water to absorb every calorie ingested).
Not Drinking Enough Water Can Be Dangerous
Did you know that 75% of Americans are chronically dehydrated? In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger. Even mild dehydration will slow down one's metabolism as much as 3% (a huge contributor to weight gain). Lack of water is the #1 trigger of daytime fatigue. A mere 2% drop in body water is capable triggering fuzzy short-term memory trouble with basic math, and difficulty focusing on the computer screen or on a printed page.
According to a survey, nearly three quarters of Americans are aware of the recommendation of drinking eight 300ml servings a day, though only 34% actually drink this amount of water each day. Most humans consume only about 6 servings of water a day and nearly 10% declared that they do not drink water at all.
Chronic dehydration has been implicated in Attention Deficit Disorder, Chronic Fatigue Syndrome and Alzheimer' Disease. If you consider the brain as an electrical energy producer like a battery, which is 80% water, it does not require a leap in consciousness to understand how a lack of simple, elemental water would compromise its most basic function. Much like a car battery that dries up and dies.
I don't know about you, but this information makes me run for my water bottle!
