Dehydration Effects

Dehydration is the “excessive loss of water resulting in depletion of body fluids” (Grosvenor & Smolin, 2006, p. 282). When the body goes through dehydration there can be many symptoms. Some of these symptoms can include: feelings of nausea, light-headedness, and feeling dizzy. Dehydration can cause symptoms to show more rapidly than any other vitamin deficiency. With other vitamin deficiencies, days or weeks can pass before symptoms are felt by the body (Grosvenor & Smolin, 2006). Symptoms can be seen when dehydrated after only an hour of activity on a hot day. Water is essential to health maintenance because the human body is more than half water. The typical adult’s body weight is about 60% water.

The minor symptoms of dehydration will go away quickly after replacing the lost water but if left untreated medical attention may be necessary. While it may be difficult to consume too much water, overhydrating can be as dangerous as dehydrating. Water toxicity can be the result of consuming too much water. Some of the early symptoms of water toxicity can be similar to dehydration. Nausea, muscle cramps, disorientation, and confusion are just some of the symptoms of water toxicity. “To help prevent water toxicity it is recommended that beverages containing dilute solutions of sodium as well as sugar, such as sports beverages, be used to replace water losses when exercise continues for more than an hour” (Grosvenor & Smolin, 2006, p. 287). Electrolytes are important because they help maintain acid-base in the body. Electrolytes are “substances that separate in water to form positively and negatively charged ions that conduct an electrical current” (Grosvenor & Smolin, 2006, p. 287). The three key electrolytes in the body are sodium, potassium, and chloride. It is important to control the amount of sodium excreted from the body because sodium helps to regulate blood pressure. If the body loses more sodium than it takes in blood pressure can drop. When this happens the body will release proteins and hormones to help the kidneys retain water and sodium. Renin is an enzyme that
