Water And Dehydration
*75% of Americans are chronically dehydrated. *37% of people make the mistake that what they think are hunger pangs are actually thirst. *Lack of hydration is the number one trigger of daytime fatigue. *Losing just 2% of body weight in water compromises your overall judgment by 25% and severely limits physical endurance.

Ways That The Body Loses Water
Physical activity and exertion / sweating
Illness / fever
Hot temperatures by way of sunlight / other
Excessively high humidity or low humidity
Breathing through the mouth more than the nose
High protein, fat, and sodium diet
Early Signs Of Dehydration
Dizziness or lightheadedness
Nausea / loss of appetite
Dry mouth, cracked lips
Mild disorientation and confusion
Fatigue / lethargy
Decreased urine output / dark colored urine
Often, and the simplest, the most telling sign of being dehydrated (even if you do not believe that you are) is dark-colored urine. The best way to know if you have enough water in your body is the color of your urine. Ideally it should be clear, with no color at all.
A person, doing nothing, at rest, loses more than half a gallon of water in a day. Once you add in exertion, climate, and other factors, this number goes much higher.
For every quart of sweat that escapes your body, your heart rate increases by about 8 beats per minute and your system becomes more stressed.
It is often hard to remember to drink enough and to remain optimally hydrated. Older people in particular lose some of their sense of thirst as they age. Waiting for a ‘cue’ of thirst to trigger your motivation to drink water is already too late. When you first feel thirst, you are already down more than a quart. A common problem is that once you get the urge to drink, it is often quenched by only a few mouthfuls, meaning that you are still ‘low’ and continue to go ‘lower’. How often do you actually drink an entire quart of water when you feel thirsty? See what I mean?
The human brain is 75% water, and human blood is 83% water, so don’t let dehydration impair your judgment and physiology. Water is number one when it comes to survival (depending upon immediate other circumstances of course). Drink enough of it. Store it. Know how to get it. Know how to purify it. Treat the resource with respect. Don’t waste it. Only 0.5% of all earth’s 326 million trillion gallons of water is potable.
