"Water is the only drink for a wise man." ~Henry David Thoreau

What is dehydration? Dehydration is the removal of water from an "object." And in this article, the "object" is you. Dehydration occurs when yoiu lose more fluid than you take in.

"I will never get dehydrated because I always drink something when I'm thirsty."

First of all, my mother always said "never say never."

Second of all, did you know that dehydration has already begun to set in by the time your brain sends the signal that you need a drink? And as we age, the signal diminishes.

Thirdly, what do you drink when you become thirsty? Hopefully, it is water which contains nutrients called electrolytes. Electrolytes include minerals such as sodium, potassium and calcium. Avoid alcohol and sugary or caffeinated drinks, which are mild diuretics.

Dehydration is not just a summer concern. Extreme cold can have the same taxing effects on your body. Making water a part of your daily consumption can decrease your risk for dehydration--a serious condition that can turn deadly. According to MayoClinic.com, you may lose more than 10 cups of water in a given day just by taking part in everyday activities. If you fail to replace that water, your health could be at risk.

What are common cuases of dehydration?
Common causes are diarrhea, vomiting, fever, excessive sweating and inadequate intake of water during hot or cold weather and exercise. Mild to moderate dehydration is likely to cuase weakness, dizziness, fatique, dry, sticky mouth, decreased urine output (8 hours or more without urination), few or no tears when crying and muscle weakness. Since thirst is a late indicator, a better barometer is the color of your urine. Clear or light colored urin means you are well hydrated. Dark yellow or amber color usually signals dehydration.

The best defense against dehydration is prevention. How can you prevent dehydration? You should drink 8-9 cusps of water per day unless contraindicated by your health care professional. Drink water 20 minutes before exercising, during and after. Eat foods high in water such as fruits and vegetables. When you have hazy, hot or humid weather and you still want to go outside, be smart. Go out early morning or early evening. Sit in a shaded area and drink plenty of water.

Please remember dehydration begins before you feel thirsty. Therefore, it is wise to bring a bottle of water with you wherever you go. In an effort to remind you to "Don't leave home without it," please pick up your complimentary water bottle in The Garlands Wellness or Fitness Centers.
