Electrolytes are minerals, such as calcium, sodium, magnesium, potassium, and chloride. These all have important roles in the body such as regulation of blood pressure, helping muscles contract, and controlling fluid balance. Having the right balance of electrolytes in your body is important.
Many drinks sold today have added electrolytes. These are often marketed as sports drinks or smart waters. Drinks with added electrolytes are more expensive than plain water, and some people might wonder if they are worth the extra cost.
ARE ELECTROLYTE DRINKS WORTH THE EXTRA COST?
The average sports drinks cost $1.68/20 ounce bottle, while drinking water from the tap only costs a few cents per day. Most healthy adults and children get enough electrolytes from the trace amounts found in tap water and from the foods they eat. Very few people need to supplement with sports drinks or smart waters. Electrolytes are found in many common foods such as dairy products (milk, yogurt), fruits and vegetables, and nuts/seeds.
There are a few situations where electrolyte drinks may be helpful to you or your children:
- Exercising for more than 60 minutes. Light activities or moderate exercise for less than 60 minutes do not require electrolyte drinks. For high endurance sports or activities for more than 60 minutes, an electrolyte drink may benefit sports performance and prevent dehydration.
- Prolonged vomiting or diarrhea. When the body loses fluids abnormally (through vomiting or diarrhea), electrolytes are also lost. Replacing these electrolytes may be helpful in preventing dehydration. If your child is ill, contact a health provider to determine the best methods for preventing dehydration.
- Exposure to heat for long periods of time. Being exposed to heat for several hours can cause the body to lose electrolytes through sweating. Depending on the temperature and the exposure time, electrolyte drinks may be helpful.
