- Water intoxication is most likely to occur during periods of intense athletic performance.
- While the daily recommended amount of water is eight cups per day, not all of this water must be consumed in the liquid form. Nearly every food or drink item provides some water to the body.
- Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body.
- Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.
- Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it.
- Somewhere between 70 and 75 percent of the earth’s surface is covered with water.
- Much more fresh water is stored under the ground in aquifers than on the earth’s surface.
- The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.
- The total amount of water on the earth is about 326 million cubic miles of water.
- Humans can only use about three tenths of a percent of all the water on earth. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.
