Your body is made up of around 60-80% water and you cannot hope to continue performing your daily chores with the same efficiency if you don't find enough water. Certainly the amount of usage of water varies depending upon the climate and activities you are involved in, but its presence is always required. In a moderate climate with low levels of activity, approximately 2 liters of water is required daily for a 160 lb person. Certainly when the climate changes or the level of activity turns to exercise, you need to increase this amount simultaneously. The first sign of dehydration may be discerned through the color of the urine. A normal hydrated body produces a pale yellow color, but a dehydrated body produces urine that is darker in color. To make sure that the body doesn't dehydrate you need to not only meet the required quantity of water, but you also have to make sure that the water is clean. The reason why you constantly need to drink water is because your body continuously releases liquids and you need to maintain those levels. The release of liquids from your body is in the form of urination, sweating, excretion, and respiration. The liquids are released so that the toxins can be removed from your body and proper hydration makes this happen along with redistributing the nutrients in the body. Water also provides the pathway for electrical impulses to travel through nerve and brain cells to activate the muscles. The brain in itself is made up of 80% water.
