Iāve been doing āarchetype meditationsā that often work with my subconscious about my body, for a few decades. Iāve had some amazing insights and results with it.
Anyway, I went through one cycle where I was having major problems sleeping, accompanied by worry. It didnāt matter about what. It was less like there was a thing that made me think of it, as that I was going to sort of obsessively think about something ā anything, whatever happened to be in my life. While not sleeping. It was driving me crazy.
I had asked for a dream to explain this to me, but as I was finally falling asleep (not there yet) I heard a voice (like a voice in a dream) say, āWhen they are stressed, you are stressed.ā and I understood it meant my kidneys.
WTH?? I was baffled. What on earth do my kidneys have to do with anything??
But I had been keeping a journal for a couple months that included my sleep times, including tried-to-sleep-and-couldnāt notes, including my diuretic doses, sometimes even including my urinary frequency and what I believed was water (not fat/lbm) weights.
This was not super clear, but when I went through it, looking carefully, I noticed that in fact, there DID seem to be a correlation ā which apparently my subconscious had noticed ā between when my kidneys would be under more stress and my attempts to sleep had canāt-stop-thinking until exhaustion. In fact in several areas I even had some kidney slight aches, and it was fairly severe in those cases.
This is only one person and anecdotal of course, but now, when I am feeling that problem, I make sure that I am drinking enough clear water, and not doing stuff that stresses the kidneys TOO much. The adrenal glands sit on top of the kidneys, and thatās what caffeine (and other diuretics) stimulate. They control the sodium balance in the body. Diuretics of several kinds work by stimulating the adrenals which in turn dump some sodium which in turn dumps water, which the kidneys have to process.
It might not always be that caffeine is keeping one awake (though it can! Or some people can drink coffee right before bed, go figure!) as that too much stimulus to the adrenal glands may cause a degree of stress on the kidneys ā or, that too little water needed for cleanly āwashing outā the body is present.
(Water intake needs to accompany body-water loss, as body-water contains proteins, itās not the same as what we call water ā body once told me this. Although a couple years of being bedridden from a heart condition with massive edema making me an immobile whale with high pressure against the skin from inside, taught that lesson. The water-edema it creates, if it soaks a towel for example, seems to never dry. Itās bizarre.)
When people shift to keto they drop a lot of water, very fast, which is suddenly greater stress on the kidneys. If my body/subconscious is correct about kidney stress being correlated with pre-sleep mental-āspinā as I call it, then making sure you have enough SODIUM ā so the water loss might be slightly slower ā and not very much stimulate the adrenals (totally without regard to caffeine itself, just focusing on adrenal-hence-kidney stress) ā might help.
Or not. Just an experimental suggestion.
