I don’t recommend it. I tried increasing my electrolytic capacity once and found some little pills that seemed ideal. I had to eat a lot of them because they were only labelled “microfood” or something like that.

The hospital staff were all very unprofessional. They all giggled when they discharged me.

Just from food. I’m heat adapted and exercise adapted and my sweat is decidedly not salty. I don’t use AC and went through that recent US east coast heat wave, so I’m comfortable at 90f/32C. I don’t lose a lot from sweat.
