The concentration of sodium we lose in our sweat (mg/L) is highly variable between individuals. The differences can be well over 10 times between low sodium sweaters and high “salty” sweaters.
Only by knowing how much sodium you lose can you devise an electrolyte balance strategy to maintain optimal body function. Electrolytes carry electrical signals around the body and maintaining electrolyte balance is key to proper muscle and nerve function. Sodium is the primary electrolyte lost in sweat.
Sodium is responsible for water regulation in the body and in the right concentrations assists in the absorption of water further aiding hydration efforts.
