I know it’s not sexy but I sweat black stuff. The instant I started using an infrared sauna my sweat went from normal smelly, nasty, chemical detox sweat to BLACK smelly, nasty, chemical detox sweat.

No doctor I’ve talked to can actually tell me what causes this but it’s called Chromehidrosis. Wikipedia says that it’s caused by the “ingestion of certain dyes or drugs.” Not sure which drug makes your sweat black but remind me to never do that drug again!

If you know how to get rid of this, what causes it or when it will stop, PLEASE let me know.
