Electrolyte function and imbalances

Electrolytes are the mineral salts in your blood that regulate various body functions.

 They help keep the fluid levels in your body healthy and are essential for energy, aiding muscle movement, and maintaining brain and heart functioning.

When electrolyte levels become too high or too low, vital body functions can be seriously affected. Imbalances occur for a wide range of reasons, but are often linked to dehydration or excessive sweating.

Important electrolytes include sodium, potassium, magnesium and calcium – signs of harmful levels of these can include: nausea, weakness, lack of energy and confusion, muscle spasms, and heart problems.

Electrolytes come from what you eat and drink, and your body helps keep the levels balanced. People who exercise strenuously often add electrolytes to their water, but usually you can keep levels balanced just by following a healthy diet and staying hydrated.
