Needless to say, water is important. Every cell, tissue, and organ in the body needs it to work efficiently. Water regulates body temperatures, transports nutrients, lubricates the joints, and flushes out toxins and wastes. A mere 5 percent drop in the body's water levels can even cause a 30 percent loss of energy.
In order to stay properly hydrated, aim to drink half your body weight in ounces daily. When you're dehydrated, toxins are reabsorbed by the body, stressing your liver and eventually weakening your immune system.
