From a drop in performance to symptoms such as muscle fatigue, dizziness and nausea loss of electrolytes can have a huge impact on your body and you might not even notice until it’s too late. While replacing these electrolytes with the right food and drink is easy, knowing how much you have lost is a lot harder. There are so many factors affecting the amount you sweat; your size, the intensity of the exercise, even the weather can play a role in how fast you lose electrolytes.
Electrolytes are substances that, when dissolved, split into small electrically-charged particles called ions. Two of the most crucial ions for the human body are Sodium (Na+) and Potassium (K+). Sodium ions play an important role in regulating body fluids, such as blood. They are also involved in the transmission of nerve impulses and certain metabolic functions. Potassium ions work to regulate muscle activity, with muscle weakness being one of the most noticeable side effects of an imbalance in potassium levels.
