Water is important for creating and sustaining life. In humans, the body is made up of about sixty percent water. Every part of our body including muscle, bone, and blood consists of some percentage of water. About a third of our total body water is extracellular fluid, which is fluid outside and between cells and water in our blood. This is the most important as the blood in our bodies delivers the oxygen and nutrients to all cells. Without the proper amount of water everyday there is a risk of dehydration. Severe dehydration can cause nerve damage, seizures, abnormal blood pressure, brain damage, arrhythmia, and even ...view middle of the document...
This is so they stay hydrated for maximum performance from their bodies. One of the early signs of dehydration is fatigue; others include headaches, loss of appetite, and dark colored urine. Continued dehydration symptoms include lack of physical performance, confusion, nausea, and difficulty concentrating.
Alcohol and caffeine can play a role in the hydration levels in the body, as they can aid in dehydration. When alcohol is consumed it is traceable in the bloodstream within minutes. The kidneys regulate water loss through urine, but alcohol stops this process by slowing down the activity of the antidiuretic hormone (ADH). This hormone increases the amount of water reabsorbed through the kidneys back into the body when water levels are low. Without the ADH activity the kidneys just pass all fluids out of the body, which can cause dehydration. This is why people get “hang-over’s”. Too much alcohol and even caffeinated drinks deprive the body of water resulting in early signs of dehydration such as headaches.
Electrolytes help in the aid of regulating fluid balance in the body. Electrolytes, sodium, potassium, and chloride separate in water and form positive and negative charged ions, which conduct electrical current. This includes transmissions of nerve impulses and contraction of muscles. These impulses are created when sodium and potassium ions move across the nerve cell membranes. Sodium regulates the total amount of water in the body. The movement of sodium is critical for communication in the brain, muscles, and nervous system because of these electrical signals. Sodium also helps in the regulation of blood pressure.
Potassium is the positive ion found inside of the cells, where as sodium is found on the outside of the cells. Potassium is essential for normal cell...
