The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
The first thing that's absolutely key for nerve to muscle communication and physical performance of any kind might not sound that exciting to you but it is very exciting. And that's salt. Nerves cells, neurons communicate with each other and communicate with muscle by electricity. But that electricity is generated by particular ions moving into and out of the neuron. And the rushing in of a particular ion, sodium, salt is what allows nerve cells to fire.

Nerve cells, neurons communicate with each other and communicate with muscle by electricity. That electricity is generated by particular ions moving into and out of the neuron. The rushing in of a particular ion, sodium, salt, is what allows nerve cells to fire. If you don't have enough salt in your system, your neurons, your brain and your nerve-to-muscle communication will be terrible. If you have sufficient salt, it will be excellent.
