Water is something everyone needs even more than food. Depending on such factors as weight, ambient temperature and rates of exertion, the human body can typically survive seven to eight weeks without eating anything. But without water, that same body can only survive three to five days without water. You can experience dehydration in hot weather within an hour.
And that’s just one of the amazing facts about water.
Did you know that:
- approximately 70% of an adult body is made up of water;
- the minimum amount of water a healthy person should drink is eight or nine 200mL glasses per day; but he or she can consume as much as eleven litres in a 24-hour period;
- drinking too much water can cause water intoxication, a condition in which water dilutes the sodium levels in the bloodstream and causes an imbalance of water in the brain;
- pure water, which is comprised only of hydrogen and oxygen atoms, has a neutral (as opposed to acidic or basic) pH of 7;
- the total amount of water on earth measures approximately 326 million cubic miles;
- of all the water on earth, humans can only use about three-tenths of one percent of this water, which is typically found in groundwater aquifers, rivers and freshwater lakes;
- by the time a person feels thirsty, his or her body has lost over 1% of its total water amount; and
- the weight a person loses directly after an intense physical workout is weight from water and not fat.
People take water for granted, but it’s precious. Without it, there would be no life, human or otherwise.
