Dehydration: How does it affect the Body? 2 Dehydration: How does it affect the Body? Primarily, water is essential to health maintenance because water is a vital nutrient in the body. It is one of the six classes of nutrients and it is needed for the body to carry out its numerous functions. The body is composed of mostly water so when our bodies are depleted of water, it is unfavorable for our health. Water provides hydration when we are dehydrated and is often replenished throughout the day because we constantly need water. Water moves throughout the body by osmosis that travels up or down a concentration gradient depending on where water is needed and where there needs to be a decrease if there is an excessive amount of water. Water also helps aid with the function of many systems in body such as the digestive system, the lymphatic system, and the nervous system. In addition, water, in its many forms contributes to a number of functions in the human body. For instance, water is basically saliva used in the mouth and in the blood, which is comprised mostly of water, it “flows through our bodies, delivering oxygen and nutrients to cells and returning waste products to the lungs and kidneys for excretion” (Grosvenor and Smolin, 2006, p. 283). Water also aids the body by producing sweat and “[regulating] body temperature by increasing or decreasing the amount of heat lost at the surface of the body” (Grosvenor and Smolin, 2006, p. 283). Sweat cools the body by producing water to lose heat in the body. Water also aids in digestive and excretory functioning. We lose a large amount of water through the digestive system because it aids in breaking down the foods we eat and we lose water through urine and feces. Furthermore, when the body does not get the water it needs, it dehydrates. Dehydration
