Being hydrated is critical to your daily energy and vitality. When you get dehydrated you can experience fatigue and brain fog—among other physical symptoms.
So how do you know if you’ve had enough water? Look at your urine. A well hydrated body produces pale yellow urine. Darker urine is sign that you need to drink more water. (Note that high levels of B vitamins and some meds can also darken your urine.)
Use the handy chart below from Precision Nutrition to see how hydrated you are. Drink a couple glasses of water if you’re on the dark side. If things just don’t seem right to you, please see your medical professional.
