What are electrolytes exactly? Electrolytes are minerals in the body that have an electric charge. They are in your blood, urine, tissues and body fluids. Sodium, calcium, potassium, chlorine, phosphate, and magnesium are types of electrolytes that are absorbed from foods you eat and fluids you drink.
The U.S. Library of Medicine mentions these roles of electrolytes:
- Balance the amount of water in your body.
- Balance your body’s acid/base (pH).
- Move nutrients into your cells.
- Move wastes from your cells.
- Help make sure the nerves, muscles, heart, and brain work properly.
Too much or too little water can affect the number of electrolytes in your body. Read more about fluid and electrolyte balance to help stay hydrated as temperatures rise.
