The easiest way to know if you are properly hydrated is to look at your urine. If it’s clear or a pale-yellow color, then you are properly hydrated. Dry skin is another sign of dehydration. If your mouth is dry, you aren’t hydrated enough to keep the mucus membranes in your mouth lubricated and your body is likely not producing enough saliva. Bloodshot eyes are another clue. Over consumption of alcohol can cause bloodshot eyes, because alcohol dehydrates you. If your joints are aching, that could be a sign of dehydration. Your cartilage and spinal discs are about 80% water so by staying hydrated, you are keeping your joints lubricated. If you aren’t well-hydrated, you may feel fatigued and lethargic. When your body is dehydrated it “borrows” water from your blood causing you to feel fatigued. If you aren’t drinking enough water, you may also feel constipated or have frequent heartburn or indigestion.
