Our body is composed of up to two-thirds water. The human brain is composed of 95 per cent water. Water, also helps regulate metabolism and body temperature. Dehydration can have a variety of effects on individuals including fatigue, short-term memory loss, trouble focusing on fine print, and even basic math abilities. Water plays a key role in maintaining normal body functions and in preventing disease.
Considering that water is essential in so many bodily functions, constant rehydration is crucial. For a fortunate few – most of us reading this included – water is always readily available. In fact, for these lucky few, the abundance of water around them can be disillusioning. Many misconceptions arise: the idea that we have plenty of water to spare, the thought that some forms of water are not drinkable, and the general feeling that this crucial source of life can be taken for granted. Two common water myths will be examined: the claim that we should all drink eight glasses of water a day, and the stigma of tap water.
