Do you know an easy way to tell if you are drinking enough water?
By the color of your Urine. Clear or light yellow colored urine is a sign that you are hydrated, if you are drinking the recommended amount of pure water.* Yellow and dark yellow urine means you are not drinking enough water.
Some (other) warning signs include: headache and lightheaded- ness, noticeable thirst, irritability, nausea, muscle cramping, dark yellow urine, difficulty paying attention, weakness and fatigue resulting in decreased performance.
*Tip: Make sure it is pure, filtered water. Beverages like seltzer water, artificially flavored waters, and sodas or coffee (with water in them) do not count, and can actually trick you into thinking you are well hydrated.
