Why does sweat sting?!


Question: I find that especially in strong sunshine, sweat running down my forehead into my eyes really stings. Anyone know what causes this and why it seems worse in strong sunshine as opposed to inside a gym.

Sometimes it does....It depends on the ration between salts and water.

Sometimes you will have a higher percentage of salts like magnesium chloride to water, this will sting on release with the water.

To avoid this, drink plenty of water. Stinging sweat is often a sign of de-hydration so have a little salt with your meal and plenty of fluids...(i.e. water)

ADDITION - after reading your adition, I think I might know what it is.

As I have said above, it is a mixture of waters and salts. As the sun evaporates the water (as its evaporation point is lower than salts) it makes the salts more concentrated, which might lead to irritation, especially with the salts based on Group 1,2 metals (like sodium, magnesium, calcium) etc.

Maybe that helps more?

It... Doesn't...
You need to seek medical help.

Cause it's full of salt and acids.

Cos it's salty.

Sweat is basically water and salt, so it would naturally sting. As of the strong sunshine, it may be something about dissolving and expansion, I'm really not sure.

I think it has to do with the ph level... that is the acidic and non acidic level. and it is not just the salt beacse tears already have salt in them

Because sweat is acid that kills bacteria on your skin. I've never been stung by sweat before tho, maybe you should check with your doctor about it!!

Are you putting any kind of face cream on your face. If you are when you sweat it will be coming off with your sweat and going into your eyes. You got to be careful, there are so many dangerous chemicals in skin care these days.

its because of salt and acid yes but they forgot one thing when you sweat your body is pushing out poisons . that's why it stings so badly

when you sweat, salt water is released. in strong sun this saltwater is dried up and the salt that is left over pinches your skin. it's like if you come out of the sea in really hot weather :D
