Water Deficiency
Posted by admin on May 13, 2008
It is important to achieve and adequate water intake, either through drinking eager or by adding water-rich foods to your diet. Dark yellow instead of pale urine is a typical sign of insufficient water intake, as is urine with a very strong odor.
If you don’t enough water, your body generally lets you know by signaling thirst. Your brain is communicating the need to drink. This thirst mechanism is not always reliable, however, especially during athletic practices and events, in infancy, during illness, and in one’s older years. For this reason, athletes should weigh themselves before and after training sessions to determine their rate of water loss and thus their water needs. Replacing at least 75% of this weight loss is advised, especially as weight loss approached 2 to 3%. Three (3/4 liter) cups of water are recommended pr pound (about half a kilogram) of weight loss. Sick youngsters-especially those with fever, vomiting, diarrhea, and increased perspiration- and older persons often need to be reminded to drink plenty of fluids. Long airplane flights are another situation that demands extra fluid intake: a traveler can lose about s cups (1.5 liters) if water during a 3-hour flight. The dehumidified air in an airplane is so dry that it induces excessive insensible perspiration and evaporation.
