According to modern medicine, the human body is composed of approximately 60 percent water. Nutrients from foods, such as vitamins and minerals, need to dissolve in water to circulate in the blood and reach various organs. Water also plays a role in improving the body's metabolism and eliminating waste. Dehydration and insufficient water intake can cause more than just thirst. They can also result in fatigue, anxiety, depression, poor concentration, restless sleep, and breathing difficulties. Moreover, dehydration can lead to the development of many diseases, including chronic inflammation, chronic pain, constipation, high blood pressure, and diabetes. Even obesity caused by overeating may be linked to dehydration in the body. For some patients, the solution to their ailments may be as simple as increasing their water intake.
