The importance of drinking water daily is often overlooked, even though every function in the human body is dependent on water. In short, without water, nothing lives.

Consider this: the adult human body is about two-thirds water, and most of the key organs and fluids in the body consist primarily of water.

The following percentages are estimates and vary slightly from expert to expert and from person to person:

  • Brain 85%
  • Heart 79%
  • Blood 85%
  • Intestines 75%
  • Lungs 79%
  • Liver 90%
  • Kidneys 83%
  • Muscle 76%


Functions of Water in the Body

In addition to the high water content in the body, basic physiology reveals the importance of drinking water in how the body functions.

Water is essential for EVERY function in the human body. Other pages on this site will explain these functions in more detail.

Just a few of the most vital functions include the following:

  • Brain functioning
  • Organ regulation and cushioning
  • Blood and lymph flow
  • Nutrient transfer and absorption at the cellular level
  • Nerve impulse movement throughout the nervous system
  • Hormone balancing
  • Temperature regulating
  • Joint lubrication and cushioning
  • Waste removal


The Body's Water Recycling System

Thus, we know water is critical to the survival and maintenance of the human body. But what is the importance of drinking water daily?

It has to do with the body’s water recycling system. The body recycles hundreds of gallons of water a day just to maintain normal biological functions.

During the recycling process the body comes up short of at least six to ten glasses of water per day.

This daily water shortage varies greatly depending on individual diet, lifestyle and environmental factors.

No Water Storage System in the Body

In addition to the daily water shortage issue, our bodies have no water storage system to supply water in times of droughtthus, the importance of drinking water regularly and throughout the day.

Contrary to popular belief, most of the water we need does not come from the foods we eat.

At best, if we are eating primarily whole, fresh foods, we may get as much as 20 percent of our daily water needs.

However, most people are eating a high percentage of processed foods, which have little if any water content.

In addition, many of the beverages we drink—such as alcohol, sodas, coffee and tea—are actually dehydrating to the body.

They act as diuretics and cause the body to lose even more fluids.


Drought Management in the Body

What happens to our bodies when we don’t drink enough? We start to experience mild dehydration symptoms, such as fatigue, headaches, feeling irritable or anxious, constipation and other digestive disorders, and not sleeping well.

When dehydration continues, the body learns to adapt with a drought management program.

However, sooner or later the ill effects will begin to appear in the body in the form of pain and inflammation. The location of the pain and inflammation often depends on where acid wastes have built up most in the body.

According to Dr. F. Batmanghelidj in Water for Health, for Healing, for Life,there are six conditions that denote chronic dehydration and drought management in the body. These conditions include:

  • Asthma
  • Allergies
  • Constipation
  • High blood pressure
  • Type II diabetes
  • Autoimmune disorders


Importance of Drinking Water for Healing

The importance of drinking water is understated in this article. My intent here is to simply provide a glimpse into the amazing properties of water in relation to the maintenance of the human body.

Water also plays a key role in the body's ability to heal itself. 

For example, medical research tells us that drinking enough water daily (at least half our body weight in ounces of water) can decrease the risk of bladder cancer by 50 percent and decrease the risk of colon cancer by 45 percent.

As you read other pages on our website, you will find more in depth information and guidelines about how drinking water can aid in disease prevention and healing of many illnesses, disorders, ailments and diseases.

Drinking water daily is quite simply the easiest and most effective way to provide a solid foundation for optimal health, fitness and longevity.
