THE RISKS OF DEHYDRATION
Our body is made up of water, from up to 80% in the case of infants to about 60% in the case of the elderly. Without water, the body begins to shut down and very slight changes in amounts of body water may affect the metabolic processes.
With normal activity, and without even feeling thirsty, we can experience dehydration. With as little as a 2% decrease in body water, you start experiencing the early signs of dehydration. When your water levels decrease by even more, like 3% or 4%, there are physiological changes that occur that may have health consequences. Body water decreases of more than 10% can be fatal.
As you lose valuable fluids, the blood thickens and the hearts pumps faster to compensate; the blood will eventually become too thick for the kidney to filter. Without rehydrating, the body can suffer permanent kidney and brain damage. It ultimately goes to a circulatory collapse, resulting in death.
1. We can experience dehydration with as little as a 2% decrease in body water with normal activity, and without even feeling thirsty.
2. Health consequences When your water levels decrease by higher levels, like 3% or 4%, there are physiological changes that occur that may have health consequences.
3. Total Dehydration A Decrease in body water of more than 10% can be fatal.
is the best way of staying naturally hydrated. Yet, sometimes, due to certain conditions, water may not be sufficient, or it may actually be a counterproductive means in the case of hypotonic dehydration.
needed per day really depends on the individual and several factors, such as age, weight, weather conditions, altitude, and activity. The Institute of Medicine determined that an adequate intake for men is roughly three liters (about 13 cups) of total beverages a day and 2.2 liters (about 9 cups) for women.
while your body may need water desperately. Dehydration is cumulative over a period of days, which means you can become dehydrated if you don't drink enough to replace what you lose on a daily basis.
