When the weather is hot, it is important to drink enough water to avoid heat-related problems.
Many people also choose electrolyte drinks, but according to experts interviewed by Real Simple, they are rarely necessary.
Electrolytes are minerals such as sodium, potassium, magnesium, and calcium. They help the body regulate fluid balance, muscle function, and the nervous system, among other functions.
Too much can also be a problem
The body loses electrolytes through sweat, urine, vomiting, and diarrhea.

With normal fluid loss, the body is able to maintain the proper balance on its own, experts told Real Simple.
According to an emergency physician at the University of Maryland Medical Center, consuming too many electrolytes can affect blood pressure and heart rhythm.
An electrolyte imbalance may also cause fatigue, muscle cramps, headaches, or nausea.
Only some people need extra
The best way to obtain electrolytes is through a regular, balanced diet that includes foods such as fruit, vegetables, dairy products, nuts, and seeds, the experts told Real Simple.

At the same time, it remains important to drink plenty of water.
Only if you exercise for an extended period in hot weather and sweat heavily, or if you lose large amounts of fluid due to vomiting or diarrhea, may you need additional electrolytes.
For most people who stay indoors or engage in normal daily activities, electrolyte drinks are generally unnecessary, even as temperatures rise, according to the experts.
