Water makes up at least two-thirds of the human body. It plays a large part in your normal functions, such as lubricating your joints and eyes, keeping your skin healthy by eliminating toxins, and facilitating proper digestion. Once the water in your body is reduced, it needs to be replaced because an imbalance between the salts and sugar in your body can affect your mood and energy.
Two early signs of dehydration are thirst and dark-colored urine. This is the body’s way of trying to increase water intake and decrease water loss.
If you don’t replace the water loss then you may experience
- dry, sticky mouth; maybe even bad breath: saliva has antibacterial properties in it, but dehydration can prevent your body from making enough saliva. If you’re not producing enough saliva in the mouth, you can get bacteria overgrowth and one of the side reactions of that is bad breath from chronic dehydration;
- sleepiness or tiredness: not enough water – not enough energy! Children are less active than usual;
- thirst or even food cravings, especially for sweets: it can be difficult for some organs which use water to release some components of your energy stores, so you can actually get cravings for food;
- decreased urine output, the mechanism that saves water;
- less tears – not enough water for crying;
- dry skin – water gives elasticity to your skin, so you are actually losing your beauty;
- headache, dizziness or light-headedness: the brain sits inside a fluid sack that keeps it from bumping against the skull, when there is water depletion the brain can push up against parts of the skull, causing headaches;
- constipation: water is major solvent, when depleted body tends to get all the water from your stomach so the stool is less liquid.
The recommendation for total water intake per day is 2.7 liters (for women) and 3.7 liters (for men). But have in mind that this includes water gained from foods and other beverages like tea and milk. So follow your body signs and water your body properly.
