The Benefits of Drinking Water

Can we seriously ask what are the benefits of drinking water? Without water we would shrivel up and die.

Water is an essential element which the body needs to function properly at every level.

  • The Body. It is estimated that the body contains approximately 70% water, the blood 80% water, and the brain 80% water. That is alot of water. But the most amazing statistic is that the liver is 94% water!
  • Body Fluids. The liquid systems of the body (blood, lymph, interstitial, and intracellular) are all predominantly water with the addition of other needed constituents such as red and white cells, nutrients, gases such as oxygen, and other necessary substances and the end products of metabolism which will ultimately be transported to eliminatory stations.
  • Body Systems. Without water in the body, all of these and many other necessary functions would become less efficient. Brain and nerve, body temperature, immune, digestive, circulatory, endocrine, nervous system, and every other body system needs it.

  • Illness. One of the benefits of drinking water is that it keeps all of your systems working properly so illness is not as prevalent. According to the water filter people at Aquasana Water Filters

    "So many common ailments and illnesses can be prevented and greatly reduced by an increased intake of healthy water.

    Headaches, hypertension, back pain, arthritis, ulcers, asthma, morning sickness, fatigue and metabolism can all benefit (and in many cases be prevented) by regulating the body's natural fluid levels."

  • Dehydration. When the body enters a state where there is too little water for proper functioning, whether it be the cellular level or at the most complex organ and system levels, it is called dehydration.

    In this state, function is hampered, illness may result, and untimate death is possible if carried too far. Another of the benefits of drinking water is that it prevents dehydration.

  • Water Loss. We all lose water from the body through respiration, perspiration, and urinary and eliminatory organs.

Depending upon our health status and activity levels the loss of water from the body will happen at different rates. One of the benefits of drinking water is that it allows our body to maintain homeostasis.

What is Homeostasis?

The body seeks a water level at homeostasis. Homeostasis means that the body will try to maintain a certain optimal amount of water in the body.

What If There Is Too Much Water in the Body?

If there is too much water in the body, eliminatory processes will kick in at a higher rate and things like urination will increase which will show up as increased volume and lighter or paler color, another of the benefits of drinking water.

What If There Is Not Enough Water in the Body?

If dehydration is present, or the body has too little water, the body will seek to retain water and things like urination will decrease and the urine will become more concentrated and darker in color, a consequence of not drinking enough water.

Because of water loss, the need for drinking fresh water for proper function as well as its need for the processes of elimination of waste products from body activity is necessary. This need for frequent drinking of water becomes absolutely essential. Providing this critical need to our bodies is definitely one of the benefits of drinking water.

How Much Water Do I Need?

The water should be sufficient to replace the water that is lost from the above mentioned body activities so that homeostasis can be maintained. The amount will vary depending upon the environmental conditions (hot or cold) and your activity levels.

Exercise and working conditions require increased amounts not only during but also before and after the activity. The benefits of drinking water do not change but stay the same with increased intake of water.

The amount required needs to be catered to you individually and thus will always be an estimate since life activities vary constantly. There are general amounts recommended and the amounts actually vary.

A Formula For Estimating Our Water Requirements

One way to estimate the amount you need is to take your body weight and divide it in half. That will give you the approximate amount of water you will need in ounces. If you weigh 150 pounds, you would need approximately 75 ounces (about 9 1/2 cups) of water per day.

This amount must also be increased or decreased depending upon your activity levels and temperatures of the air around you.

What Kind of Water Should I Use?

We would recommend that the water be free of harmful contaminants such as lead and as pure as possible from bacteria and other harmful organisms.


The United States has one of the safest water supplies anywhere. This is because the EPA (Environmental Protection Agency) has established standards of quality which local suppliers of water must follow. They can be reached at

They have a lot of information about water, what is required for safety, and can supply answers to you for most of your concerns.

If your local water falls below the standards they have set, the supplier of that water can be fined and will be required to bring it up to standards as well as report it to you and to the EPA.

You need to be aware that the EPA does not control well water and if you use that source you may want to have the water checked periodically.

Water Filters

It is a very good idea to purchase a home water filter.

I will never forget the day we got our six month water report from the city, a government controlled system, and it simply stated, "THE PROBLEM HAS BEEN FIXED. THE CONTAMINATION WAS NOT SIGNIFICANT FOR MINIMAL HEALTH BENEFIT. (Whatever that means!!)

I guess we had been drinking contaminated water and didn't even know it!!! After that we beat a hasty path to purchase a home water filter system.

These systems easily attach to your faucet or can be placed under the sink out of the way, and depending on the quality and type you get, almost anything can be removed from the water.

This includes physical substances down to a micron in size. It can also allow bacteria and other living organisms and other chemicals such as lead and mercury to be removed from the water.

And clean water is especially important for growing children. They discuss how to store your water, how it effects your health, and many other things.

We feel that their systems work extremely well and are convenient to use, their price is very reasonable and their filters last a long time. The necessity of frequent filter replacement can increase the cost of your unit significantly.

You can even sign up for "water for life" and they will automatically ship your water filters every six months.

Outdoors. If you love hiking in the outdoors the way we do, you can also purchase water filters that work well for hikers and campers who want to draw water from a stream or other source.

Don't forget the benefits of drinking water apply on the trail as well, maybe even more. These units can be purchased from most sporting good stores.

There are many types of these as well. Be sure to do comparisons before purchasing.

Travel Abroad. One last recommendaton is that if you are going to travel outside of the United States, you should evaluate the water of those locations. Foreign countries do not all have guidelines for safe water.

Therefore, if in doubt, purchase bottled water especially in third world countries or take a water filter with you. Also be aware that the cost of that water may have an escalated price in as much as they are aware of foreign travelers who have these concerns who are visiting their country.
