One can go weeks without food but only days without water. Water affects the functioning of our organs and our ability to fight disease. It helps us to maintain a healthy weight and cope emotionally. The positive effects of drinking plenty of quality water can be seen in all aspects of our health and appearance. In a typical day, you lose 2 to 3 liters of water. If you don’t replace it, your body will naturally pull the water away from your skin, nails, and hair – the fundamentals of good looks – to the critical systems that need it for basic good health. Drinks with caffeine such as coffee, tea, and soft drinks have a limited water replacement value as they are diuretics and therefore promote water loss. Fruit, vegetables, and juices all contribute well to water replacement; however, they also contain calories that, for a growing segment of the population, are a problem. Water, on the other hand, is totally calorie free. This is why it is recommended that we drink 8 ten ounce glasses of water each day. It is the most sensible way to meet our fundamental water needs.
