Are you cramping up at all ? If not Id not worry.
I sweat like a pig in a sauna in a jumper and I very rarely have problems.
You can try nuun tabs when it's hot but for 95% of the time water should be fine.
I totally agree with this. I'm the sweatiest exerciser I know and I've never yet suffered from cramps or any other 'salt depletion' type symptoms. I went through a short phase of using Zero tabs when I started running ultras just because everyone I spoke to about it said I'd need them on longer runs, but after a couple of races where I couldn't stomach them and I was pouring out my Zero juice and refilling my bottles with plain water, I just ditched them. I do use gels in races though, which usually have salt in them...
I read something a while ago about your body finding its own 'salt equilibrium' through sweating, and that if you're a salty sweater - face and clothes crusted with it - that it's because you eat too much salt and have too much of it in you and your body's just trying to get rid of it.
Wondered if this might have something to do with some folk apparently functioning much better with salt tabs and some folk really not getting on with them. Cause I hardly eat any salt at all. I don't use salt in cooking, I actually don't even have salt in the house, and I actively avoid salty packaged foods. So I wonder if that's why I don't get on with salt tabs, and maybe people who normally have a lot of salt in their diets are the ones who get most benefit from them because their body is used to functioning in an over-salted state...
I don't know either way, like I say, I just wondered...
