Water is the second most important substance, after oxygen, that we need to consume in order to survive.People can’t survive more than a few days without water. Our bodies are 65-70 % water, our blood is 95 % water and the brain is around 75 % water.
Since such a large percentage of our bodies is water, it’s logical that it plays a great role in how our body functions. Water regulates body temperature through perspiration, aids digestion, transports nutrients and oxygen to our cells, removes toxins from our body and it has so many more crucial functions. The digestion of solid foods depends on the amounts of water in the body. Constipation is a frequent symptom of dehydration. Increased water intake, along with higher fiber intake, will usually eliminate this problem.
Water flushes toxins from the body. Water helps our joints move freely. The cartilage found at the ends of long bones and between the spinal discs contains high percentage of water, which serves as a lubricant during the movement of the joint. Joint pain usually decreases with increased water intake and flexing exercises that bring blood to the joints. Water also acts as a cushion between internal organs and protects them.

Water and weight loss
Water plays a great role in weight loss. Dehydration leads to excess body fat, poor muscle tone and size, decreased digestive efficiency and organ function, increased toxicity, joint and muscle soreness, and water retention. Water works to keep muscles and skin toned. It also helps the body metabolize stored fat and this is probably one of the most significant factors in losing weight.
People lose about 2,5 to 3 liters of water every day. About 500ml is lost just from breathing alone. The other 2 liters are lost in perspiration and urine.
So how much water should you consume a day?
A non active person should consume about 14 ml of water per pound of bodyweight. An athlete should consume about 22-23 ml per pound of bodyweight. That is about 3.9 to 4 liters if you are a 180lb athlete. The more you exercise, the more water you will need. Remember to spread your water intake equally throughout the day.
