Just as a car cannot function without oil, our bodies cannot function without water. After oxygen, H2O is the most important component of the body, responsible for 65-70 percent of its composition. And of this, 80 percent is dedicated to the skin.
Water is the medium for various enzymatic and chemical reactions in the body. It moves nutrients, hormones, antibodies, and oxygen through the blood and lymphatic systems, and it also helps form the matrix of the skin. Devoid of water, the skin becomes dehydrated, resulting in a dry, dull tone.
It's likely that the moment a person feels thirsty, mild dehydration has already set in. To keep the complexion looking smooth and blemish-free, drink water upon waking and continue drinking it throughout the day at one- to two-hour intervals. At least six 8-oz. glasses of water should be consumed daily and more if you are exercising, perspiring, and/or in hot weather. Ideally, intake should be between ten and twelve 8-oz. glasses of water a day. One note: Don't increase water intake all at once, as the kidneys and digestive system need time to adjust. Add one 8-oz. glass every day or every second day.
What counts toward your daily water intake? Just the basics: water and herbal tea. Caffeinated beverages and alcoholic drinks are diuretics that can contribute to dehydration, requiring even more hydration after drinking.
Not only is water important for skin health, it can also play a key role in the prevention of disease. Drinking eight glasses of water a day can decrease the risk of colon cancer, bladder cancer, and potentially even breast cancer.
