Is it normal to have salty sweat

I see a lot more salt residue on my kit when I go running in Arizona than in Florida, for example. Also bear in mind that salt residue will be more visible on darker kit, so factor that into your observations. Oh, and ignore salt residue found on your kit after a triathlon where the swim was in the sea, for obvious reasons! If you have a very high sweat rate , it has to be said that the white marks might be a result of the sheer volume of sweat rather than because you necessarily have very salty sweat.

This is why I rarely run without a cap or visor with a built in sweat band in the summer! Blood pools in your legs and not enough oxygen reaches your brain for a short period of time, causing the head rush or feeling of faintness. This used to happen to me regularly when I was in full time training, especially during the Summer, and losing a lot of sweat and salt can make athletes more susceptible. If you often underperform or feel like crap after working out for a long time in hot conditions and by that I mean more so than those around you, or more than you do after similar exertions in cooler conditions then your net sodium losses might be on the higher side.

Another sign is lots of white marks and sweat on your neck and arms, and if your sweat tastes really salty or stings when it gets in your eyes. The free online version of the test involves nothing more strenuous than filling out a questionnaire, and the full test is hardly more taxing.

Both the online and in-person test tell you how salty a sweater you are, the latter is just far more precise.

For the moment, though, making sure you're drinking lots of water if you're sweating a lot is a key way to stave off dehydration. In the future, as sweat sensors become more common, we'll be able to look at the messages our sweat is sending with the touch of a button. Right now, though, we can still understand our bodies better by knowing our sweat inside out.

While your sweat on its own can't indicate a particular health issue, if you notice something off with your sweat, that could be good info to bring to your doc. By JR Thorpe.

But, if they lose too much salt due to extreme temperatures, vigorous exercise, or fever, salt is easy to replace.

If someone with CF is going to be in hot weather, exercise hard, or has a fever, drinking extra water with a little salt added and eating more salty foods can prevent the dangers of too little salt, which are dehydration or heat stroke.
