Drinking water helps your skin because if you’re not drinking enough fluids, you can become dehydrated. Dehydration leads to an increased accumulation of toxins and chemicals in the body and this leads to a diseased-looking appearance.
When we drink plenty of fluids, our urine should be light yellow, clear, odorless and have no traces of dark coloration from blood or the presence of other adulterants. But when too much fluid is excreted, which can happen due to fever or vomiting for example, the kidneys help regulate electrolytes in cells by retaining sodium – this process results in an increase in blood sodium levels called hypernatremia which can be fatal.
