Why am I sweating salt crystals?

Some people’s sweat contains more salt than others, particularly people who drink more water and eat a lower-salt diet, states RunnersWorld. Individuals can replace the salt lost through sweating by adding more salt to their diets.

Symptoms of salty sweat include stinging eyes when sweating, sweat that burns cuts or scrapes, salty-tasting sweat, a gritty feeling on the skin after working out, and white streaks on clothing or skin, according to RunnersWorld. To replace salt, these people can drink sports drinks or vegetable juices instead of plain water, add salt to foods when cooking, and choose saltier foods such as pickles, chicken broth and pretzels.
