(BlackDoctor.org) — The vast majority of our body’s composition is water. Just think about it – our blood is about 83% water, our muscles are 75% water, and even our bones are almost 25% water. Water is the essential ingredient of an enormous amount of our body’s essential functions, and without it human life is simply not possible. Over all, the human body is approximately 2/3 water.
The Physiological Functions of Water
Water performs many functions within the human body and is the medium in which many important biochemical processes take place. Our cells are themselves small watery universes, and you may be surprised to learn just how essential H20 is to your survival and well being.
Water’s importance is underscored by the following list of its universal importance:
• Water is the main ingredient of saliva, blood, stool, and urine
• Water cushions the brain and joints to prevent them from damage and shock
• Water lubricates joints, the brain and digestive tract
• Water is the medium for the transportation of nutrients and waste
• Water is essential to the maintenance and regulation of body temperature (through perspiration)
• Water is important to the proper digestion of food
• Water is a major part of lymph fluid and assists in the efficient function of the immune system
• Water prevents dehydration of the cells and organs
The Effects of Water Deficiency
The lack of sufficient water in the body can lead to many symptoms, some of which can be life-threatening if not reversed.
Symptoms may include:
• Decreased urinary output and dark, concentrated urine
• Kidney dysfunction and failure
• Kidney stones
• Abnormal blood clotting
• Bladder dysfunction
• Poor temperature regulation
• Confusion and loss of consciousness
How Do We Lose Water From our Bodies?
Water loss occurs in ways of which we may or may not be conscious, and the average adult human can lose up to 2 or 3 quarts of water from the body every day, all of which must be replaced. Sneezing, breathing, urinating, perspiring and defecating all contribute to fluid loss.
Your urine is an excellent way to monitor your level of hydration. If your urine is clear or light yellow and the amount of urine you produce is relatively large, you are well hydrated. If your urine becomes scant in amount and takes on a darker, more concentrated color, you are becoming dehydrated and should rehydrate immediately. If your urine has become excessively dark (cola color), you could be in grave danger and should possibly be rehydrated under medical supervision. If you or someone you know is indeed dangerously dehydrated, it is generally better to seek medical attention and have the rehydration supervised by medical professionals.
