Health is like a bank account: when you are in a perfect state of vitality and getting all the power nutrients your tissues need to function at their best, your “health account” balance is at 100%. Water, water, everywhere, nor any drop to drink…Those famous words, written over 250 years ago, convey some idea of the importance of good old H20 to us humans. Water is life, truly, and when we are healthy, but especially when we are sick, our bodies need water more than they need food, sleep, or exercise. Hydration is critical to good health. This shouldn’t be surprising given that your body is nearly 70% water.

An important component of just about every function that takes place within us, water is the major part of our saliva, stool, and urine and it also cushions and lubricates brain and joint tissue. Drinking three to four liters of quality water per day will keep you hydrated and transform your health. Staying ultra-hydrated by drinking 3-4 liters of clean, filtered water per day will dramatically improve the way you think and feel. When we are hydrated, our cells function optimally, our digestive system works wonderfully. It transports nutrients and carries waste away from body cells, and it helps regulate body temperature by distributing heat and cooling the body through perspiration.

However, you lose water each day when you go to the bathroom, sweat, and even when you breathe. You lose water even faster when the weather is really hot, when you exercise, or if you have a fever. Vomiting and diarrhea can also lead to rapid fluid loss. If you don’t replace the water you lose, you can become dehydrated. Different people need different amounts of water to stay hydrated. Most healthy people can stay well hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than 8 glasses may be enough. Other people may need more than 8 glasses each day.

Bringing water into exam may improve grades. Presumably by keeping themselves hydrated, students who bring water to drink while they sit exams may improve their grades. There might be several possible physiological and psychological explanations for this association, one being that there might be a direct physiological effect of hydration on thinking ability, and the other, that consuming water might help students calm down and reduce the anxiety that is known to damage exam performance. It is probably a good thing for students to try and keep themselves hydrated while sitting exams.
