  • Sea salt, externally applied -- the best thing I've found so far

Hi everyone,

I wanted to share a rather unusual solution that has been a blessing for me so far, and might help others as well: namely, externally applied sea salt.

I have been using this (or baking soda, which seems to be not quite as effective as sea salt) as an after-the fact remedy for many years; that is, when I already have symptoms, I apply the sea salt, and the symptoms are then largely cleared. However, my current situation, which I have described in another post -- my Kindle was hijacked by Amazon with an automatic firmware update and it now causes me symptoms, so I am forced to look at my laptop screen alone when I am working, instead of alternately at the laptop screen and at the Kindle (the text I would be working on was on the Kindle) -- led me to experiment a bit more, and I discovered that the sea salt works preventatively as well.

The method is to wet my forehead, take a smallish-to-moderate amount of fine sea salt in my hand and run a little water on it from the faucet, forming a kind of pastish consistency (not too dry and not too wet), then slap it onto my forehead so that it sticks there. I ensure it covers a moderate area of my lower forehead: my brow just above the area between the eyebrows, and perhaps a half an inch or so to either side, as well as a larger area above that (three or so inches upward and two or so inches to each side from that higher part. But I haven't worked it out to an exact science, that's simply what I've been doing and it has been working). It can be a bit messy: some salt ends up falling on the ground, bits of it fall onto my face, a small amount of salty water also drips down onto my face for around a minute or two afterward.

I used to do this only to clear the symptoms after screen use (in cases where I wasn't using the Kindle or printing things out), but now that I have no screen that I can look at without symptoms, and the symptoms are really unpleasant (and also affect the quality of my work), I experimented further and found that I can do it preventatively. That is, I slap the sea-salt paste onto my forehead and, with clumps of salt occasionally falling off and salty water dripping a little and everything (this is mostly an issue at the very beginning, after a minute or two the salt tends mostly to just stick on there), I sit down at my computer to work, salt on my forehead, often for hours. When I am working, I then get absolutely no symptoms for as long as I use the computer. If I read a lengthy article on the screen, it will eventually start to affect me a little with time, but then if I revert back to working, or step away from the computer -- with the sea-salt paste still on my forehead -- the symptoms gradually clear again.

I know this probably sounds quite strange, and I can already hear a chorus echoing through the cyber-ether: How could this possibly work? What could the mechanism of action be?

I don't have an answer to this. In some circles, sea salt and baking soda are said to clear, to "suck up" "negative" energies. Modern, respectable people don't tend to believe in this sort of thing. And I consider it doubtful as well, since I have tried attaching my laptop screen to a projector, and I got very bad symptoms from the projected screen (without the salt on, to be noted) -- if there were "negative" energies, how would they be reaching me from the reflected light on the wall, far away?

I actually don't remember how exactly I came upon the idea of doing this (after screen use), it was so many years ago. But for me it works extremely well. Except that it's a bit messy (actually I may have made the process out to be somewhat messier than it really is), looks pretty funny if someone sees you with the clump of salt on your forehead, and would be rather impracticable in public places. (Though as an after-the-fact remedy, I suppose one could escape to the restroom and do the "procedure" there, leaving the salt on for a few minutes to clear away the symptoms).

Note again that I use fine, not coarse sea salt. And one could experiment with baking soda as well -- I have had mixed results, varying with different brands of baking soda. Currently, fine sea salt is my go-to.

I realize that this method may sound strange, but the effect has been so dramatic for me, and I know that so many of us are having such a horrendous time with this problem, that I felt it makes sense for me to share it. I would be very interested to know, if any of you try it out, whether it helps you.

Note of course that we may not all have the same problem (and we certainly don't all have the same symptoms). I don't get headaches or eye pain or any of that. I turn into a "zombie," is the best way I can describe it: it's as if my brain turns to putty, I start feeling disoriented, my thinking becomes slower and clumsy, I start making mistakes when I type, I start feeling disconnected with the world around me, I can no longer interact smoothly with other people, and my joy and richness of perception of the world is sapped. It is also worth mentioning that I can watch videos on any screen indefinitely with no ill effect. If I am looking at anything else on the screen -- particularly reading text -- I get the symptoms.

Very curious to hear about your experiences if you decide to try out the "sea salt paste."

    I wonder if it has any similarities with this stuff, wet salt is cooling if I remember my high school chemistry correctly.

    could be magnesium, etc in the salt? trying now with some celtic grey salt. quite refreshing at least. burns.

      I doubt the salt is doing anything other than holding the water on your skin longer, leading to an extended evaporative effect, which cools the skin longer. Thats probably where your relief is coming from.

        ensete Thanks very much for sharing your thoughts. I realize the mechanism of the sea salt is as yet unclear, but I am sure it is quite different from simply holding water on the skin leading to cooler skin. My screen-use symptoms are very strong and debilitating, and the effect of the sea salt is remarkable, to the extent that when I have it on my forehead, I get absolutely no symptoms at all, for hours at a time. I can't imagine that keeping my forehead continually wet, with water alone, or that simply having cooler skin on my forehead, would have such an effect. But thanks again for sharing your thoughts and contributing to the discussion and exploration of the "sea salt phenomenon" -- all ideas and sharing-of-experiences are of course very much welcome!

          I'm sorry, but this is yet again one of those "solutions" that lower our chances to achieve any real solution.

          Imagine a doctor or scientist investigating this topic and reading that people smack gobs of sea salt to their forehead, which helps them tolerate screens better.

          Yeah, lets all go to a customer meeting and in the middle slap a moist ball of sea salt to the forehead, saying, "this help me tolerate LCD screens"

            Maxx Thanks for your input. Yes, this is the obstacle: the strangeness of the method, both in its appearance and in its unclear mechanism of action. This is why I expect some people will probably read my original post and won't bother trying it because it seems so odd.

            What I would suggest would be to simply: give it a try. See if it helps you, and report back.

            If this helps others anywhere close to as much as it has helped (and is helping) me, it would be major. And the only thing to lose would be the couple dollars spent on the package of sea salt, and a bit of salt on the floor.

            As for the doctors and scientists, they certainly haven't helped us much yet. Rather than wait for them, I'd prefer to have something that works now. And for me (and for one other poster here so far), this works now.

            I see this as one of two sides. One being medical related experiments to attempt to mitigate issues related to eyestrain and related phenomena, the other being empirical "triggers" of this issue (like dithering/FRC, PWM or other physical properties of LCD panels) that still exist and should still be solved.

            Speaking from experience, potentially having something attempting to interfere with normal visual processing when eyes are damaged and working around the issue is probably just "buying time" until you become more sensitive, at which point certain workarounds are moot.

            It's important we don't conflate the two when attempting to investigate the technical causes of this issue and in communication with other stakeholders (like in communication with OEMs)

              Thanks for the interesting reflections. Just regarding your second paragraph: nothing would be interfering with normal visual processing here: the salt just goes on the forehead. (If the salt went into the eyes, that would interfere with vision!)

              It's also possible that the problem is not one of eye damage at all. Or that for some of us it is and for some of us it isn't.

                I was referring to the cause of "this issue" as being the problem interfering with visual processing and other things related to eyes. Not the salt.

                  Please explore! you could try the cooling patches or different kinds of salt, and observe if it helps.

                    Thanks, this is definitely worth exploring! The scientific mindset of experimenting systematically would be an excellent one here. As for me, for the moment I've found what works very well, and don't enjoy getting the symptoms, so I'm not too eager at the moment to experiment for the sake of "research" and finding out more. My approach is purely pragmatic right now. But if anyone else is interested in experimenting in this way, it would indeed be fabulous.

                    Try a menthol rub on your forehead and see if you get the same effect. There are several "anti migraine" stick that are sold OTC that "work" by evaporation cooling the skin.

                    got zero effect with mortons sea salt, but good effect with liquid magnesium drops(evaporated seawater)

                      JTL I get it, but we'll never be able to control the lights in our extended environments on an ongoing basis, so we'll need hacks like this one to cope.
