Why does my sweat Smell like Chlorine?

Are you washing any of your workout clothes in bleach? If so, try using less or if your washer has the option for an extra rinse, use that.

I'm assuming by chlorine, you might also mean ammonia. You either need to eat more carbs or drink more water. Here is a link that might help explain:

i sweat chlorine… but that’s because I’m a swimmer.

when you swim hard, you sweat, so your pores open and let chlorine in…
the next time you sweat, the chlorine comes out, and you start to reek of chlorine.

but you’re not a swimmer

Maybe it’s because you had too much salt in your food? Cause the chemical composition of salt is sodium and chlorine.

I had this problem on and off for years. If your sweat also tastes very salty you may want to have a Cystic Fibrosis test.
