The body constantly losing water - between 2.5 and 3 liters per day - through the exercise of its normal functions, it must be replaced to keep the body healthy. Ironically, the feeling of thirst appears as the body has already begun to dehydrate. That is why it is very important to drink water often, without waiting to be thirsty. At the moment one begins to feel thirsty, the body has already dehydrated from 0.8% to 2% of its weight.

These are some of the many roles water plays in body functions:

Water and your brain

The cellular tissues of your brain are made up of 85% water. When you are not well hydrated, your brain may be the first to feel the effects, with headaches, lack of concentration and a reduction in your ability to memorize in the short term. Even your ability to calculate and your psychomotor dexterity can be reduced. This is because dehydration reduces the level of energy production in the brain. Studies have shown that an individual's ability to concentrate decreases gradually as soon as the body is subject to a water deficiency of 1 to 2%.

Water and your blood

Blood is 95% water. It is the water that transports the nutrients to the cells of your body and eliminates waste. When you are dehydrated, the mechanism that regulates blood pressure will not work properly which can lead to an increase in blood pressure.

Water and your skin

The skin is the largest organ of the human body. It is made up of 70% water. Every day we lose water through evaporation through the skin. The environment in which we live, with air conditioning and heating, low humidity, soaps and other cleaners, can damage the upper layers of the epidermis and reduce its ability to maintain a level of hydration suitable. If you do not drink enough to compensate for the water your body loses, your skin becomes dry. Moisturizing creams can cure the symptoms, but the simplest solution is still to hydrate from the inside by drinking a glass of water.

Water and your cells

Every cell in your body needs water to function properly. On average, one person consists of 50 to 75% water, 2/3 of which are transported by the cells. If there is not enough water in the body these cells can not effectively perform their roles, such as transporting nutrients and disposing of waste.

Water and your bones

The bones are composed of 22% of water on average. It is always the water that ensures the flexibility of the movements of the joints. The cartilage at the end of each bone contains water to lubricate the movements of your joints. When they are well hydrated, both surfaces slide well together, when they are dehydrated, the danger of friction increases which can cause the deterioration of the joints and cause conditions such as osteoarthritis.

Water and your heart

The heart is 77% water. Clinical studies have shown that proper hydration can improve the way your heart works and thus reduce the risk of developing heart disease.

Water and your kidneys

The kidneys are composed of 80% water. Their function is to eliminate the waste that the body produces, this waste is dissolved in water. When the body runs out of water, the waste is not removed effectively, which can damage the kidneys. The National Kidney Research Foundation recommends drinking 2 liters of water a day to reduce the risk of kidney stones.

Water and your liver

The liver is 73% water. Its function is to transform body fat into usable energy. But if the liver is forced to help the kidneys in their functions because of insufficient water intake, the body will store extra fat when they would have been burned if enough water had been consumed.

Water and your lungs

Your body needs water to breathe. A person loses between ½ and 1 liter of water a day just by breathing. The lungs are 80% water. To absorb oxygen and eliminate carbon dioxide our lungs must be permanently moistened. Dehydration can make breathing more difficult.
