was sind elektrolyte — what can you do yourself?

Electrolytes are charged minerals like sodium, potassium, calcium, magnesium, chloride, and phosphate that are vital for nerve signals, muscle contractions, and fluid balance. What you can do yourself: maintain a balanced diet rich in fruits, vegetables, nuts, and adequate water. After heavy sweating (exercise, heat), an unsweetened electrolyte drink may help. Supplements are usually unnecessary unless a deficiency is confirmed by a doctor. Caution: too much sodium raises blood pressure; too much potassium can be harmful if you have kidney issues. The provided context does not cover electrolytes; this answer is based on general medical knowledge.
