- What happens if we don’t drink enough water?
• Answer:	The first signal is that we are thirsty (occurs at 1% loss).
•	We may become depressed or irritable.  It becomes difficult to think clearly.  
•	Water deficiency leads to dehydration.  We may experience a dry mouth, lethargy, mental confusion, reduced skin elasticity, sunken eyes, fever, scanty dark urine, and constipation.
•	At 20% water loss death may soon occur.
It’s easy to be slightly water deficient yet not know it.  You may just feel a little more tired or irritable than usual.  Drink some water and see if it helps.
