Urine frequency, volume and color are probably the best and most useful indicators of our body’s hydration level. If urine frequency and volume are less than normal, then your water intake has probably been inadequate. Dark yellow urine means you are probably dehydrated, whereas pale to light yellow urine color is a sign of normal water balance in your body. Totally clear urine indicates over-hydration. Importantly, thirst is not always the best indicator for dehydration; if you are over the age of 50, or have high levels of fatigue or stress, your body turns off your thirst receptors. So it is important to not wait until you feel thirsty to drink.
