Question: Is there a medical condition that causes large amounts of salt to produce on your skin? I was recently on an outdoor outing, when I got into my car I rubbed my hand down my arm and my hand was covered with salt. What could cause this?

Answer: Excess salt is secreted in pretty much every bodily fluid. Some is normal, you sweat and as it dries it leaves behind a residue.\nIf you think this is a lot, then try cutting down your salt intake. Read labels, some foods contain lots and you just don't realise it.\nDehydration can also cause this, as the salt is secreted with less water and therefore is more concentrated.\nAs always, if you have any genuine concerns see a doctor.
