After a workout, many people turn to sports drinks like Gatorade or Powerade instead of just water. These drinks claim to be packed with electrolytes, which are thought to need replenishing after intense physical activity or, frankly, after bouts of diarrhea.
But what exactly are electrolytes, and does our body really require us to constantly top them up?
As per the Cleveland Clinic, electrolytes are substances that help your body with a variety of functions, such as facilitating chemical reactions and maintaining fluid balance. They get their name from their ability to carry a positive or negative charge when dissolved in water, which helps with muscle contractions and controlling hydration levels.
Sodium, magnesium, potassium, calcium, chloride, phosphate, and bicarbonate are all types of electrolytes. An imbalance, whether too much (hyper-) or too little (hypo-), can lead to bodily responses such as weakness, muscle cramps, fatigue, or confusion.
Electrolytes are generally obtained through a balanced diet. A variety of medical issues or conditions can affect electrolyte levels, which can be assessed through blood tests by healthcare professionals. Typically, electrolyte imbalances occur due to physical exertion and the subsequent loss of fluids through sweating, and alcohol consumption can also contribute to dehydration.
If you’ve lost electrolytes, should you replace them? According to the Harvard School of Public Health, electrolyte depletion generally happens after an hour or more of intense physical activity. Light exercise, such as a moderate jog or weight training, doesn’t usually cause any noticeable effects. It’s only after prolonged sweating from heavy activity that you may want to replenish electrolytes quickly with a sports drink, particularly if it contains high levels of sugar.
Plain water is often the best option for most stomach-related illnesses. The sugar in sports drinks can sometimes aggravate symptoms. In such cases, an electrolyte solution like Pedialyte may be a better choice, but only if the symptoms are causing significant fluid loss.
The takeaway? Unless you’re involved in serious physical activity or dealing with a medical condition, there’s usually no need to be concerned about electrolyte levels.
