What is the importance of water in our life?

Low fluid consumption in general and low water consumption in particular make it difficult for the body to eliminate toxins. As a result, low water consumption increases the risk of cancer. Drinking enough water is another basic habit for good health, as you've probably heard 1,000 times. It's true: you need to drink at least six to eight glasses of water (48 to 64 ounces) each day. That means having a glass of water every two waking hours. Don't wait until you're thirsty; schedule regular water breaks throughout the day instead.

Water is essential for life. The average amount of water in your body is about 10 gallons. We need to drink at least 48 ounces of water per day to replace the water that is lost through urination, sweat, and breathing. If we don't, we are likely to become dehydrated.

Even mild dehydration results in impaired physiological and performance responses. Many nutrients dissolve in water so that they can be absorbed more easily in your digestive tract. Similarly, many metabolic processes need to take place in water. Water is a component of blood and thus is important for transporting chemicals and nutrients to cells and tissues. Each of your cells is constantly bathed in a watery fluid. Water also carries waste materials from cells to the kidneys so they can be filtered out and eliminated. Water absorbs and transports heat. For example, heat produced by muscle cells during exercise is carried by water in the blood to the surface, helping your body maintain the right temperature balance. The skin cells also release water as perspiration, which helps keep you cool.

Several factors are thought to increase the likelihood of chronic, mild dehydration: a faulty thirst "alarm" in the brain; dissatisfaction with the taste of water; regular exercise that increases the amount of water lost through sweat; living in a hot, dry climate; and consumption of the natural diuretics caffeine and alcohol. Diuretics are substances that draw water out of your cells and increase the rate of urination. Surprisingly, if you drink two cups of water and two cups of coffee, cola, or beer, you may end up with a net water intake of zero! Be aware of your "water budget." If you drink coffee or other dehydrating beverages, compensate by drinking an additional glass of water.
