The importance of adequate water Intell X Pro intake is poorly understood by most people in proper brain health. In his book "Your Body's Many Cries For Water" Dr. helidj, MD explains, water that the brain uses as electrical energy is generated by the water drive of the energy-generating pumps. With no water (dehydration) the level of energy generation in the brain is decreased. Many functions of the brain that depend on this type of energy become inefficient. This inadequacy of function is recognized as depression. This"depressive state" caused by dehydration can lead to chronic fatigue syndrome. In other words these labels of disease are really just seen to be associated with stress. A dehydrated body is a stressed body.
