Why You Should Drink Electrolytes

​

• Electrolytes are minerals with an electric charge that conduct electricity in the body, playing a crucial role in bodily functions.
• The main electrolytes in the body include sodium, potassium, calcium, magnesium, and chloride, which are found in body fluids like blood, sweat, and urine.
• Electrolytes help send electrical signals between cells, allowing muscles to move, the heart to beat, and the brain to function properly.
• They also maintain the balance of fluids inside and outside cells, ensuring proper hydration and enabling nutrient exchange and waste removal.
• Factors such as exercise, illness with fluid loss, hot weather, certain medications, fasting, and specific diets may require electrolyte supplementation to replenish levels and maintain optimal health.

You've probably heard the term “electrolytes” tossed around your whole life (especially after recovering from the flu or breaking a sweat in the summer heat) but do you really know why they're so important?
If your answer is no, it’s time we changed that! Electrolytes make a big difference in how you feel and how well your body functions, and if you understand their power you’re more likely to get plenty of them. So let’s demystify these amazing minerals!


Electrolytes 101: What Are They, and Why Do You Need Them?

Electrolytes are minerals that have an electric charge. More specifically, these minerals separate into positively or negatively charged ions when mixed with water, and ions have the ability to conduct electricity.


You may not know this, but the human body runs on electricity. Our cells conduct electrical currents, and our nervous system uses electricity to send important messages to the rest of the body. And that’s why electrolytes are so important.
Electrolytes help send electrical signals between cells and play key roles in the many processes that happen within each cell. Electrolytes allow your muscles to move, your heart to beat, your lungs to breathe, and your brain to think—some pretty crucial stuff.


Electrolytes also make sure there’s the perfect amount of fluid inside and outside of your cells. Your cells are pretty picky about their water content and for good reason! If the amount of water gets out of balance, cells can swell like an overinflated balloon or shrivel like a raisin. Either scenario can have serious consequences, such as organ damage or death.


Luckily, electrolytes are the ultimate hydration harmony keepers. They help maintain harmony through a process called osmosis. Osmosis is the movement of water molecules through a semipermeable barrier, like a cell membrane, from an area with more water and fewer electrolytes (a less concentrated solution) to an area with less water and more electrolytes (a more concentrated solution) to create balance.


Put simply, during osmosis, electrolytes help determine the direction water moves. When there’s a higher concentration of electrolytes and other particles on one side of a cell membrane, the water molecules are drawn toward that area. This movement is crucial for maintaining fluid balance within cells and tissues.


An Intro to Each Electrolyte

The main electrolytes in your body are sodium, potassium, calcium, magnesium, and chloride. Now that you have a better idea of what electrolytes do in general, let’s dive into what each of these does specifically.


Calcium

Did you know that calcium is the most abundant mineral in the human body? Your body needs calcium to:

• Maintain the structure and strength of your bones and teeth
• Clot blood to prevent excessive bleeding
• Contract your muscles
• Maintain a normal heart rhythm

Top Food Sources: Dairy Products, Leafy Greens, Tofu and Soy Products, Sardines, Almonds


Magnesium

Magnesium plays a role in more than 300 chemical reactions that are crucial to your body’s overall health and well-being. Your body needs magnesium to:

• Convert food into energy
• Relax and contract your muscles
• Maintain a healthy nervous system
• Support bone health and density

Top Food Sources: Pumpkin Seeds, Spinach, Black Beans, Cashews, Almonds


Sodium

Sodium is a key component of table salt, which is known as sodium chloride. It’s not only essential for human health but also for the health and well-being of all animal life. Your body needs sodium to:

• Transport nutrients across the intestinal lining into the bloodstream
• Maintain proper fluid balance
• Contract and relax muscles
• Send signals between nerve cells

Top Food Sources: Unrefined, Ancient Sea Salt


Chloride

Chloride is the second half of the dynamic duo that makes up salt, and it’s part of the reason salt enhances the flavors of foods. Chloride interacts with taste receptors on the tongue in a way that balances and brings out other flavors. Your body needs chloride to:

• Regulate white blood cells that contribute to the body’s immune response
• Digest food
• Maintain proper nerve function
• Support balanced pH of bodily fluids

Top Food Sources: Salt, Seaweed, Rye Bread, Olives


Potassium

Potassium is the third most abundant mineral in your body, and most of this potassium (about 98%) is found inside your cells. Your body needs potassium to:

• Maintain the balance of fluids and electrolytes within the body
• Keep your kidneys functioning properly
• Help regulate blood pressure
• Support a healthy heart rhythm

Top Food Sources: Bananas, Avocado, Spinach, Sweet Potato, Salmon


Does Everybody Need to Replenish Electrolytes?

Clearly, everyone needs electrolytes to survive….just look at how many critical bodily functions depend on them (and the examples we mentioned above are just the tip of the iceberg). But does that mean everybody needs electrolyte supplements? Or are the electrolytes we get through food enough?


There are a lot of factors and conditions that may be a sign you need more than what you get from food alone. Here are some life situations to consider when deciding whether you should use an electrolyte supplement:


• Exercise and Physical Activity: You know that you lose significant amounts of electrolytes through sweat during prolonged or intense physical activity (especially in hot and humid conditions). But you also lose electrolytes during moderate activity, even when it doesn’t feel like you’re sweating. Replenishing electrolytes, particularly sodium and potassium, is essential to maintain proper fluid balance and prevent dehydration.
• Illnesses with Fluid Loss: Certain illnesses, such as gastrointestinal infections with vomiting and diarrhea, can lead to significant fluid and electrolyte loss.
• Hot Weather: In hot weather, especially if you’re exposed to high temperatures for extended periods, you can lose electrolytes through sweat. This can lead to dehydration and imbalances in electrolyte levels.
• Hydration After Drinking Alcohol: Alcohol consumption can have a diuretic effect, increasing urine production and leading to fluid and electrolyte loss. Replenishing electrolytes along with fluids after drinking alcohol can aid in rehydration and restoring electrolyte balance.
• Medical Conditions or Medications: Certain medical conditions or medications may disrupt electrolyte balance in the body, causing your body to need significantly more or less of particular electrolytes.
• Prolonged Fasting: Prolonged fasting can result in electrolyte imbalances because you’re not taking in any (or enough) electrolytes through food.
• Your Diet: Your diet can impact whether it’s a good idea to take electrolyte supplements. Low-carb diets, for example, trigger changes in your body’s fluid and electrolyte balance, and it’s typically a good idea for people on these diets to supplement with electrolytes. People who eat diets that contain very little processed food can also benefit from getting more sodium because they’re getting very little in their diet.
• Pregnancy and Nursing: When you’re pregnant, it’s recommended that you increase your water intake, and anytime you increase your water intake, you’ll want to increase your electrolyte intake to keep them in balance. When you’re nursing, breastmilk is your baby’s primary source of electrolytes, so you’ll want to make sure you’re taking in enough for both you and your little one.
