The Human Body And Water: Dehydration

1015 words - 4 pages

It is a Sunday afternoon and you are doing laundry in your two-story house. This involves running up and down the stairs from your bedroom on the second floor to the laundry room on the first floor. carrying a very heavy basket filled with laundry. After a few trips you notice you are getting tired, light headed, and your mouth is dry and sticky; you wonder why that is. When you exert yourself physically you are using more water to carry the glycogen that creates more energy, and you sweat to cool down your body; so you need to drink more fluid to rehydrate yourself. When you reach the kitchen you open the refrigerator you are faced with two options, drink water or drink a sports drink. Your wonder which is better for rehydration.
Before you can know which is better for rehydration you must first discover why you need to hydrate in the first place. According to Martina Navratilova, water is used in the body as an assistant to the loading and storing of glycogen in the body, glycogen is the element that energy is converted from in the muscles of your body. Water carries red blood cells in the veins and arteries and is vital to the life of the cells in your body due to the nutrients the water carries (5 Water Functions in the Body). Water also helps the body maintain homeostasis due to the production of sweat and the evaporation of water off of the skin that efficiently cools the body (5 Water Functions in the Body). Water lubricated the joints so they can move loosely (Navratilova, Martina). Water is vital to the body and no human can survive more than 3-5 days without water (5 Water Functions to the Body). The next question is if water is so important, then why where energy drinks made?
Energy drinks were made to replace the solutes lost from the body when you sweat. When you perspire, you lose mostly water, but you also lose sodium, vitamin c, urea, carbohydrates (sugar), ammonia, and lactic acid, the solute that attracts mosquitoes (“Q’n’A”). Energy drinks were made with sodium, carbohydrates, and protein to help rehydrate the boy faster. The thing about energy drinks is that they work. The amount of sodium and glucose in the drink makes you want to drink more (Caldwell, James) and energy drinks are made mostly of water and due to the amount of carbohydrates and sodium, the body actually does rehydrate faster as opposed to just drinking water, however water is not a bad thing to drink it still dehydrates the body (Fitzgerald, Matt). You now wonder where the solutes go after you drink the water or sports drink.
According to Tim Goodwin, water is absorbed through the walls of the large intestine and the remaining solutes are absorbed in the small intestine. Capillaries are connected to both the small and large intestines’ walls and the capillaries transport the water and nutrients through the body until a cell needs it or it reaches the kidneys and is filtered out of the body if it is not usable. If a cell does need water or a certain...
