Hydration, not the most exciting of the four foundations for learning. How can hydration compete with exercise? Exercise really gets the heart pumping. Nutrition is also a bit more interesting. Frankly, it has more texture. Now, you would think that hydration could beat sleep for excitement, . . . . . but not when you’re a parent.
Water is the driving force of all nature. Leonardo da Vinci
Hydration, the step-child of nutrition, is important, even if it is not exciting. Our bodies are made up mostly of fluid and this accounts for over half of our body weight. Our brain floats in fluid. We know that even mild dehydration can lead to physical problems ranging from headaches to faintness to a weak rapid pulse. However, did you realize that a mere 1-2% decrease in optimal hydration can result in drops in cognitive performance? And while cognitive skills decline, irritability is shown to go up. And this will happen before you even feel thirsty (in fact, feeling thirsty means you are more than a little dehydrated).
