Heat and Dehydration

 For those living in Texas and Oklahoma, summer 2011 heat is like nothing that they have ever experienced in recent years.  It is draining, exhausting  and unbearable from morning till night and in some part of these states night heat  is worse. Heat will lead to dehydration – a condition that occurs when the loss of body fluids, mostly water, goes above the amount that is taken in. With dehydration, more water is released out of our bodies than the amount of water we take in through drinking.
