Why do I have something like salt on me in summer?

I eat too much salt, and I like salty food myself. When you lick your mouth after sweating while playing basketball in winter, it seems that there are particles on your face after stopping sweating, just like salt. In summer, the human body is prone to sweating, and some salt will be excreted with sweat. If you take too much, the phenomenon you mentioned will appear. It doesn't matter, but pay attention to healthy diet!
