We all know the importance of drinking water, and quite simply put, if you don't drink enough fluids, you will die. But do you know the exact reasons you should be drinking water, other than the age old saying that "it's good for you?"

Well, there's a lot of reasons why it's good for you, from improved brain health, to helping dissolve fats and soluble fibers, and below are six ways in which water benefits your body (that you may not have thought of before).

It helps maintain your body fluids: The body is made up of around 60 percent of water, which is used to conduct a number of different things. According to WebMD, these include regulating body temperature, the creation of saliva, digestion of food, and the absorption and transportation of nutrients across the body.

It can keep you full: Now we're not suggesting you live off water, but water, when combined with food has the ability to make you fuller, quicker. Which can result in you eating less, and therefore losing weight.

Helps your skin look radiant: Your skin helps prevent the loss of water, but when you are dehydrated your skin can appear wrinkly and dry — having enough water will, therefore, keep you looking radiant.

Promotes brain function: Your brain is made up of mostly water, so when you drink a lot of water your brain can function to its full potential, helping you to focus better and improving your concentration levels. Lack of water results in several issues, including struggles to focus, memory loss, and problems with your sleep.

Eliminates dehydration related illnesses: Headaches, joint pain, and cramps are often caused by dehydration, so drinking water will help to alleviate these symptoms. Dehydration can also cause fatigue and weakness.

Flush out waste: The digestive system needs water in order to function.
