Hydration benefits: Why water is the essence of good health
The American Journal of Clinical Nutrition recommends drinking up to 3 liters of fluid a day. Water is vital for all cell function. It helps your brain to produce hormones and neurotransmitters, supports the lubrication of joints, keeps your skin cool through sweating or respiration, and your body to excrete waste.
It is little surprise the Center for Disease Control and Prevention places an emphasis on drinking plenty of fluid as upwards of 75 percent of Americans suffer from chronic dehydration. The average adult can survive up to three weeks without food but, take water away, and you might only last for 100 hours, according to Duke University professor Claude Piantadosi.
