Sodium Deficiency (neurally-mediated hypotension) Symptoms associated with inadequate sodium intake include undue fatigue after moderate exertion, lassitude, headache, sleeplessness, and an inability to concentrate. (9) Neurally-mediated hypotension (an abnormal neurocardiogenic reflex in individuals with structurally normal hearts) is a common cause of recurrent lightheadedness and fainting which can develop as a result of inadequate sodium intake. After an episode, fatigue is prominent and may last for a long while. (10) This abnormal reflex is common in chronic fatigue syndrome. When patients were tested on a table designed to tilt them upright at various angles, all except one showed evidence of neurally-mediated hypotension as compared to only 4 of 14 normal controls; moreover, 9 patients reported complete or nearly complete resolution of CFS once this pathophysiologic response was adequately treated.

Pass the salt, please!
This happened to me, during a period when I was drinking a LOT (1+ gallon) of water each day. Couldn’t understand the constant headaches, dizziness, “mini-blackouts” (lasting a few seconds). Only when I got sick with something and restricted my water intake did I notice a change — that my salt-deficient syptoms disappeared within hours. Thankfully, I made the connection. When I did some research, I discovered that I’d been peeing all my electrolytes down the drain for the previous two months.
I still drink a good amount of water, but I monitor the amount. And I’m sure to add a sprinkle of salt to almost every meal.
The "natural" goals of the salt police and other control freaks.
