Is drinking salt water dehydrating?

by Devrie

We have been trying the water/sea salt thing for about a week now and have already noticed some benefits.

However, I have just now seen some sites that say you should not dissolve the salt in the water, but rather dissolve the salt on the tongue and then drink water. They say dissolving the salt in the water will make you more dehydrated. Is this true?


I first heard about the recommendations to add a natural salt to drinking water in the books by the late Dr. Batmanghelidj, who is considered one of the foremost water experts.

His recommendations were specifically for people who were drinking the amount of water necessary for optimal hydration, which is one-half ounce of water per pound of body weight. Thus, for example, a person who weighs 200 lbs. would need to drink about 100 ounces of water, or about 3 quarts daily.

If someone significantly increases their water intake, especially within a short period of time, too much sodium may be flushed out of the body through the urine, creating a mineral imbalance. Thus the need for natural salt replenishment.

In addition, as you may know, the only type of added salt I recommend are the natural unrefined salts, such as Celtic sea salt and Himalayan pink salt.

Is it better to dissolve the salt on the tongue or put it in your drinking water?

I have also seen the recommendations for dissolving salt on the tongue via the Friends of the Water Cure site. I have not been able to determine if this recommendation is actually from Dr. B himself (I have never seen it in his books) or if it is from someone else.

The site also does not explain why salt on the tongue followed by water is biochemically different than salt in water.

However, from my personal experience, I believe it is better to put a pinch of salt on your tongue before drinking water rather than putting it in your water.

I do NOT add any salt to my water because I don't like the taste.

I do put salt on my tongue before drinking water when I am intentionally increasing my water intake due to higher levels of stress, intense or prolonged exercise, hot weather, or if I have not been eating well.

I have seen a noticeable difference when I do this. In the past when I have added salt to water, I did not feel any difference and I avoided drinking the water because of the taste.

As always, I believe it is helpful to take it slow when making dietary changes, such as increasing water intake and adding natural salt, and figure out what works best for you.

The bottom line is that when increasing water intake, it is a good idea to replenish natural salt as well as minerals (80 trace minerals are found in the Celtic and Himalayan salts).

Once you have established a daily water drinking habit, you may need only a small amount of natural salt on occasion. The key is balance.

This also means making sure you are NOT getting too much of the unhealthy, refined white salt that is hidden in almost every type of processed food.

Will drinking natural salt in water make you more dehydrated?

To be honest, I don't know for sure. But I think there must be some truth to the statement that salt water is dehydrating because as most of us know, if we were stranded on a raft in the ocean, drinking sea water would cause extreme dehydration and possibly death.

However, this is primarily because of the extremely high concentration of salt in sea water.

According to Batmanghelidj, we need about 3 grams of salt (one-half teaspoon) for every one-half gallon of water OR one-fourth teaspoon for every quart.

That seems like way too much salt for most people.

The amount of salt you add depends on so many factors, including health conditions, activity levels, stress levels, size, weight, age, and so forth. In general, I recommend using less than more.

I like the water cure guidelines and approach for drinking water and salt that is outlined by Russell Mariani, director of the Center for Functional Nutrition. See reference below.

The type of water you drink also makes a difference. If you are drinking a mineral-rich spring water, artesian well water, or alkaline ionized water, for example, you would need to add less salt than if you are drinking distilled water or reverse osmosis water since these waters are de-mineralized.

Response to Celtic Sea Salt on Tongue
by: Nancy

I agree with you. I believe it is much better to put salt on the tongue before drinking water rather than putting salt in the water.

The statement I made in my original response that you are commenting one was written several years ago. At the time I was just experimenting with putting natural salt in water and on my tongue.

I have updated my original post and look forward to watching the YouTube video you recommended. Thank you for bringing the outdated statement to my attention.

I wanted to comment on the statement regarding that it doesn't make a difference if putting the salt on the tongue or just drinking it in water. It makes a big difference.

Barbara O'Neill explains this very well on YouTube - 10. The Importance of Salt & Water, Barbara O'Neill - She explains this in the first 12 minutes of the video. Highly recommend folks watch it. Life changing for me.
