2. Improves your Mood
Research has shown that even mild dehydration can impact your ability to think and negatively affect your mood. One good indicator of your hydration level is the color of your urine.
The darker color that your urine is, the less hydrated you are and the lighter the color of your urine, the more hydrated you are.
If you have dark urine, are feeling tired, and are a bit grouchy, drinking some water can help improve your overall mood as well as improve any fatigue that you may be feeling.
