Sweat Changes the Signal
Hydration is not only water; your nerves also depend on electrolytes moving correctly.
The Science
- Sodium helps cells fire signals, hold fluid balance, and respond during hard effort.
- Heavy sweating loses water and salt at the same time.
- Needs vary by body, heat, training, diet, and blood pressure, so context matters.
The Protocol
- For long hot practice, plan water plus electrolytes, food, and smart breaks.
- Do not overload salt or copy someone else's bottle.
- Stop and get support if you feel dizzy, confused, or unusually weak.
