19. Prevents Cancer
When your body becomes dehydrated it can fill up with toxins. These toxins can then grow within the cells of the body and cause them to behave erratically. The cells could multiply and go out of control. When this happens tumors and other harmful things can occur.
Drinking ample amounts of water is thought to help reduce the risk of these toxins becoming harmful or turning into cancerous tumors as the water will help rid the body of the toxins and keep the systems of the body working the way that they should.
