From Health Facts
Dehydration is the term used to describe a deficiency of water. A mere 2% drop in your body's water supply can trigger signs of dehydration. It is estimated that the majority of people are mildly or chronically dehydrated. Mild dehydration is one the most common causes of daytime fatigue.
Many people believe that thirst is the first sign of dehydration. Yet, typically if you are thirsty you needed water long before that. The older you are or the less healthy you are, the less you're able to sense that you're thirsty. On the other hand, excessive thirst and increased urination can be signs of a more serious medical condition. Talk to your naturopathic doctor if you experience either.

Prevention and Treatment
To ward off dehydration and make sure your body has the fluids it needs, make water your beverage of choice. Most healthy adults can follow these tips:
- Drink 1/2 your body weight in ounces of water per day.
- Drink fluids slowly by constantly sipping throughout the day.
- Don't drink caffeinated drinks or alcoholic beverages, which can actually have a dehydrating effect.
- When flying in an airplane, drink plenty of water and avoid alcohol.
- Drink water before, during, and after exercise--slowly!
- Call your doctor if you have a temperature over 102 degrees Fahrenheit, or severe cramps.
- Carry a water bottle whenever possible, especially when participating in outdoor activities in warm weather.
- Remember that fluids can be lost through sweat as well as from diarrhea.
- Check with your naturopathic doctor to see if your symptoms or conditions alter your need for water.
- Riboflavin, a B Vitamin, will make your urine bright yellow.
- Although uncommon, it is possible to drink too much water. When your kidneys are unable to excrete excess water or when the daily consumption of water is too high, the electrolyte (mineral) content of the blood is diluted, resulting in low sodium levels in the blood, a condition called hyponatremia. Endurance athletes, such as marathon runners, who drink large amounts of water, are at higher risk of hyponatremia. In general, though, drinking too much water is rare.
