Water serves as a lubricant in digestion and almost all other body processes. The water in our saliva helps facilitate chewing and swallowing, ensuring that food will slide easily downs the esophagus. Water also lubricates our joints and cartilages and allows them to (pardon the pun) move more fluidly. When dehydrated, the body rations water away from the joints. Less lubrication equals greater friction and that can cause joint, knee and back pain potentially leading to injuries and arthritis. Even our eyeballs need plenty of lubrication to work well and remain healthy.
Our bodies can control over-heating through perspiration from sweat glands in the skin and from evaporation which produces a cooling effect. Blood is also routed into areas close to the surface of the skin where it can be cooled and then carried back to the interior of the body. Conversing in a cold environment, the skin maintains proper body temperature by shunting the blood away from the exterior surface thereby conserving heat within the body. The movement of water within our cellular systems also transports vital blood plasma which is 92% made of water. Blood plasma play a critical role in buffering the body’s pH, circulating antibodies from the immune system, and regulating osmotic balance which all helps to maintain proper body temperature.
Water helps our bodies remove toxins in many different ways. Water flushes toxins and waste from the body through urination and perspiration. Water helps reduce constipation and aids in bowel movements which ensures that wastes are removed quickly and regularly before they can become poisonous in the body. This waste buildup can occur in the body if dehydration becomes a
