How does dehydration affect nerve health in general and peripheral neuropathy in particular? What is the effect of a dry room in winter (e.g., below 30%)? Does dry skin make PN worse?

One site claims:

"Nerve function: Microstreams exist along the length of nerves which transport nutrients and conduct energy along microtubules to the synapses to transmit messages. Dehydration disrupts proper nerve function, resulting in the sensation of pain."

BBC:

Dehydration occurs when more fluid is lost from the body than is taken in. This causes an imbalance in important minerals, such as sodium and potassium, which are required for muscle and nerve function.
