The old advice about eating a banana to stave off cramp is exactly the same as drinking some salt water. Muscle and nerve cells in the body work through small and frequent impulses (electrical charge movement) which causes a cell to do whatever it's supposed to do, in the case of muscle cells, this function is contraction.
Each individual impulse passing a cell is called an action potential. An action potential works like this:
- Cell is happily sitting with -60mV potential
- Sodium ions (salt - Na+) start to pass in to the cell through Na+ channels while potassium ions (banana - K+) stop moving out of the cell. This increases the potential of the cell.
- At -40mV, calcium ions (Ca2+) start to move in to the cell through the calcium channels in the cell membrane.
- At +10mV the cell has reached its peak potential and begins to repolarise. Basically the opposite happens, K+ leaves the cell, Ca2+ ions are actively transported out of the cell. The potential begins to decrease again.
- At around -30mV the Na+ and K+ pumps swap their activity levels, this means that K+ begins to re-enter the cell while Na+ leaves to restore the original balance of ions either side of the membrane and leave the cell at -60mV.

interesting factiod (cant find the link where i read it) when a patient experiences a reaction to a placebo they have proven that the patients body has actualy manifested the chemical/nutrient neccessary for the effect they experienced,
I also have an unrelated story on Pickle Juice that I might share sometime. Has nothing to do with cramps, but Y2K.
Ok, OUCH. Waking up at 3:30 AM with the muscles on the top of my foot and front of my calf seizing up is new to me! The uncontrollable contraction of the muscles did not respond to my rolling around in the bed moaning, massaging the muscles or forcibly bending my foot against the painful muscle contractions. I HAD to get up, and when I stood on it, it eased somewhat.
Walking, however, was a double-edged sword. Each time I took my weight off of the offending foot, the pain was excruciating. (I'd have thought the opposite would be true. Shows you how much I know about leg cramps in the night.)
Oh, and the look of it!!! I could actually see the seized up muscle in action... by the weird indention at the point of contention.
NOW DON'T YOU TELL ME to eat a banana because I'm low on Potassium, my friend. Fact is, I just recently bought bananas for the first time in ages, and have eaten one the last few evenings. (Otherwise, I'd had thought the same as you!) I actually, considering the circumstances, wondered if the influx of Potassium contributed to the leg cramps in some mysterious way-- maybe due to the absence of some other mineral.
Honestly, I wasn't thinking much except *OUCH* as I stood at the kitchen sink filling up a glass of water while bouncing on one foot in a desperate, sleepy stupor. I did feel thirsty. And that's when it came to me. I can't explain how I knew. Spirit told me? Collective Consciousness? Take your pick, it's all the same to me-- but the point is, I spied the Sea Salt in the salt grinder, and I knew it would help.
I put a few of the unground chunks in my mouth and drank some more water, still justa bouncing in klutzy sleepy stupor. Within 10 seconds of ingesting the rock salt (one piece dissolved in my mouth, the other two went down with the water) the leg cramps just instantly 'Turned Off' --as if someone had flipped a switch.
Coincidence or not? You be the judge. I did, however, find a wealth of info with a simple google search...
Leg Cramps & Sea Salt
While I'm at it, I seem to remember reading it is more dangerous to have too little salt than too much...
Too Little Salt in your Diet?
And while I'm at it, an interesting factoid about your first home-- Amniotic Fluid has the salt content of seawater...
Amniotic Fluid like Seawater
I'm throwing all of this out there for your information, and input, ATS! What experience do you have, if any, regarding Leg Cramps and Sea Salt? What are your thoughts on my experience vs. what you thought to be true?
(There was a recent thread about Cholesterol being 'wrongly accused' in heart disease. Is Sea Salt suffering the same accusation?) Just askin' !
