Actually, you don't.

Sweat is the body's method of cooling. When you exercise or otherwise become overheated the body gives up water from the blood and evaporation cools the surface of the skin. Since blood contains salt (normal saline), some of the salt is sent to the surface of the skin along with the water. If the body DIDN'T leave salt in sweat, the level of salt in the blood would become too high, causing health risk and possibly even death.

As the water evaporates from the sweat, the salt is left behind and if you sweat enough the salt will start to form crystals.

The basis of water movement is the presence of salt. Where there is sodium you find water.

So when you sweat water moves out of the body losing electrolytes like sodium. Thus sweat taste salty.
