The Importance of Hydration

Other ingredients such as salt, alcohol, sugars, can harm the body when taken in excessive amounts. It’s important to drink other beverages only in moderation, and refer to water as the primary


Dehydration can feel like a punishment to certain parts of the body. Without enough water, the brain can contract or shrink, pulling away from the skull and causing pain known as a dehydration headache. Other symptoms are muscle cramps, dizziness, rapid heartbeat and, if severe, fainting.
