A member asked:

On extended tropical trip. high perspiration levels, but my sweat has no salt taste, zero. using more salt on food plus electrolytes. any dangers?

NO danger.: Sweat has very little salt. The reason you taste salt in your sweat is because the saliva has no salt so any little salt in the sweat makes it "salty" No problem drinking electrolytes, you will get rid of any excess in the urine.

Salt less sweat: One's body will retain sodium when adapted to hot conditions. This has been well studied in soldiers in desert regions over weeks and months. The sweat becomes lower and lower in sodium. This is conservation. Yes, adding sodium on food plus potassium and magnesium is essential.
