What is intravenous rehydration?
By the time a person feels thirsty, dehydration has already kicked in. This not only means that the urge to quench thirst is strong, but unfortunately, that the body's mood, mental ability and energy levels have already been compromised. "Our thirst sensation doesn't really appear until we are 1 or 2 percent dehydrated. By then dehydration is already setting in and starting to impact how our mind and body perform," says Lawrence E. Armstrong, professor of physiology at the University of Connecticut. Armstrong was also the lead researcher in a study on the subject of hydration, which reinforced the importance of drinking plenty of water.
Ever wonder what the actual water content is of some popular beverages? Coffee is somewhere around 98 to 99 percent water. Soda is about 90 to 95 percent water. Wine tends to range from 80 to 85 percent water. A light beer is close to 90 to 94 percent water. Tea is approximately 98 percent water. On the surface, based on these numbers, is it any surprise that the average person today tends to think they have easily satisfied their body's daily crucial requirement for water? The 8 to 10 glasses of water that are often preached seems quite easy to attain given the water content of beverages like these. How many coffees and sodas are expended at the office each day? What about the after-work beer or wine relaxer? And when the thirst signal calls again, reaching for another soda seems to satisfy that desire, so it seems.
Dehydration is one of the most overlooked and basic causes of disease.
