Oral vs IV Rehydration

Athletes Take Heed

When considering oral vs IV rehydration, oral is better. Why? Here you will discover what we think, what we know and what can we prove.

Both oral and IV hydration have been used by high-performance athletes through the years. It is common in the NFL, collegiate football, marathon and triathlon sports.

In third world and some second world countries, IV rehydration for athletes is a standard of care.

One Size Does Not Fit All

Research from 2005 found oral re-hydration to be more effective in children than IV fluid (IVF) rehydration, because it was faster to give and reduced hospital admissions in a certain group of small children.

When someone is unconscious or semiconscious, IV administration is the preferred form of hydration by healthcare professionals. But what about the rest of us? Is there a better way?

Oral vs IV Rehydration: Health Pro View

Because of the commonality of IV use, health professionals believe it is more effective than oral rehydration. It is thought that the IV will provide for far greater performance over oral hydration.

However, this is wishful thinking. There is no science to back this mindset.

Benefits Of Oral Hydration: The Science

Oral hydration has been found to be just as effective as IV hydration and studies show that oral hydration may actually be more beneficial. Oral hydration is also safer. It does not require medical staff to deliver it.

The safety and speed of administration alone makes it a better choice on the field of sports activity.

The study looked at the response to IV and Oral Rehydration. After 20 minutes of rehydration, the subjects exercised untill exhausted. The room temperature was 98.6 degrees Fahrenheit with a humidity of 50%.

The findings....

During exercise, the....

Blood plasma (the liquid part of our blood) and other blood-pumping values were about the same for IV and oral rehydration.

Temperatures were lower with oral rehydration.

Feeling of thirst was lower in the oral rehydration group.

Feelings of exertion were lower in the oral rehydration group.

Performance improvement for the oral rehydration group were only slightly better.

Oral Rehydration: The Better Way

While the results were about the same in the IV vs Oral hydration methods, there are a number of unseen advantages. The risk of infection, bruising, discomfort may be considered minor reasons to avoid the IV. Any invasive treatment to the body has greater risks than natural treatments.

Additionally, the need to move an athlete to a secure place to provide the IV creates further challenges.

Add to this the thirst perception and the feeling of not being exhausted, the oral rehydration has a lot of reasons to consider it as being superior.

By following an effective oral rehydration protocol, athletes are taking charge of their own health naturally. This will help the athlete become more in tune to their body's needs and when it is speaking to them. This in turn may result in greater performance.

So, when it comes to oral vs IV rehydration, oral wins the competition.

Our Grandparents Knew About Mixing Hydration and Eating!

It is amazing how so many things that are new to us were common knowledge in the past. One basic practice of the Water Cures protocol is to drink at least 30-45 minutes before and 2 1/2 hours after a meal. This is not a new thought however. Notice what a magazine from 1925 had to say...

"Drink plenty of water two hours after each meal; drink none just before eating; and a small quantity if any at meal time. Do not take a bath until two hours after eating a meal, nor closer than one hour before eating. Drink a full glass of water both before and after the bath." (Golden Age, Sept. 9, 1925, pp. 784-785)

Heal Your Headache It Worked For Me

Hi, my name is Sharon. The webmaster of this site is my nurse, my personal water coach and my husband.

As this site was first being built, I had a headache and as usual took an Ibuprofen. Impatient for it to start working, I decided to try the Water Cures. I took a pinch of salt and a glass of water. Then I took a second pinch of salt and another glass of water. My headache was gone in less than 5 minutes.

From my personal experience, it usually takes 30 to 45 minutes for Ibuprofen to work. Some have found it takes ibuprofen 24 minutes to start working.

Yet on the Water Cures protocol, my headache was gone in 5 minutes.

Its simple: give your body what it needs and your body will give you what you need, the ability to feel great.

Water Cures was the solution for the elimination of my headache. It is what I will use from now on.

Why not give it a try yourself.
