neurons need sodium, they need magnesium, and they need potassium in order to function. We do tend to get dehydrated at night.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
However, some days I'm very, very hungry, and so I do ingest water, which contains electrolytes, so that means sodium, magnesium, potassium, for the simple reason that sodium, magnesium, potassium are required for neurons to function properly. It's part of the way they generate electrical activity. As well, Ingesting electrolytes for me can quell hunger.
because neurons use salt, sodium and potassium and magnesium, the so-called electrolytes in order to perform their magic of chemical and electrical signaling, everything you do depends on chemical, electrical signaling and all that chemical and electrical signaling requires electrolytes in some form or another neurons run on the passage of ions like sodium in and out of their cell membranes are, I should say, across their cell membranes to be accurate.
And sodium, potassium, and magnesium are important in order for nerve cells to function. In fact, they are actually the components, the ions, that pass across those lipid membranes, those little fatty membranes that we were talking about earlier, that allow the neurons to generate electrical activity and communicate with one another.
sodium plays in the way that neurons function. In fact, sodium is one of the key elements that allows neurons to function at all, and that's by way of engaging what we call the action potential.
The electrolytes are critical to the function of every cell in your body, in particular the neurons, the nerve cells. So I've talked about before on this podcast, neurons, nerve cells, require adequate sodium and potassium, as well as magnesium, in order to fire action potentials, which are the electrical signals that allow neurons to do everything from generate focus and attention, allow you to learn, and generate neuromuscular connection, and allow you to exercise or train or do any kind of skilled activity with a high degree of output.
they require adequate levels of sodium potassium and magnesium if you were to learn the biology the physiology of the action potential the firing of a neuron something we teach every first year Neuroscience student and I'd be happy to teach you if you're interested you'll hear about sodium rushing into cells and potass ium entering and leaving cells in order to allow neurons to communicate
