How Do Electrolytes Help You When You’re Sick?

The last time you were sick with the flu, you probably reached for water or ice chips to stay hydrated. However, did you know that plain water lacks the minerals you need to rehydrate when you’re sick?1,2 When you come down with the flu, especially if you’re suffering from vomiting, diarrhea or even excessive sweating, your body is losing important minerals called electrolytes.3 But what are electrolytes, and how can you restore them after losing them through your bodily fluids? Learn more about electrolytes, where to find them and how to hydrate with them after a bout of the flu.

What Do Electrolytes Do?

Electrolytes are minerals that have a positive or negative electrical charge when dissolved in water.1 They exist in your blood and other bodily fluids to help regulate your body’s functions, including water balance, the acidity of your blood, and muscle and nerve function.2 The average adult body is made of 60% water, which means that almost every cell in your body contains electrolytes to help you function.1

The Importance of Replenishing Electrolytes

However, despite the importance of electrolytes for your overall health, your body regularly loses electrolytes through sweating and urination.1 Losing too many electrolytes without replacing them can cause an electrolyte imbalance, which can lead to a variety of health issues, including heart, muscle and breathing problems.1

When you lose electrolytes, you need to replace them with fluids or foods that contain electrolytes. Unfortunately, plain water doesn’t contain electrolytes.2 The most common electrolytes include:2

  • Calcium
  • Sodium
  • Potassium
  • Chloride
  • Phosphorous

How Your Body Loses Electrolytes

If you’re eating a balanced diet and staying hydrated, you probably don’t need to worry about your daily electrolyte intake.3 However, there are times when your electrolytes can drop sharply. For example, if you get sick with a virus or flu that’s causing prolonged vomiting or loose stools, you’re losing more electrolytes than usual.3 In those cases, it’s important to replenish your electrolytes to restore your body’s previous water balance and to prevent dehydration.3

What to Drink to Restore Your Electrolytes

If you’re experiencing a fever, vomiting or diarrhea, it’s important to stay hydrated. When you’re sick, experts recommend replacing eight ounces of water with eight ounces of a low-to-zero-sugar sports beverage or rehydration drink with electrolytes to help your body replace lost minerals.3

How to Stay Hydrated When You Have the Flu

Staying hydrated and replenishing electrolytes when you’re recovering from the flu can be challenging, especially if you’re struggling with nausea and vomiting. Drinking a lot of fluids at once isn’t recommended, as it can exacerbate nausea and make you feel worse in the moment.4 Instead, set a timer on your phone to remind you to drink fluids every fifteen minutes. Taking two to three sips at regular fifteen-minute intervals throughout the day is enough to help you rehydrate.4

In addition to drinking plain water, supplement your hydration with an electrolyte drink or powder. Avoid alcohol and caffeinated drinks, including soda, coffee and energy drinks. If you’re struggling to keep down regular clear fluids, try freezing your electrolyte beverage and turning it into ice chips or a popsicle.5

Managing Flu Symptoms with an Over-the-Counter Medication

In addition to hydrating with electrolytes, help manage your flu symptoms with an over-the-counter (OTC) medication.5 For body aches and pains or a fever, try an OTC medication with acetaminophen.5 If you’re suffering from a dry cough, manage your symptoms with a cough suppressant like dextromethorphan.5 Lastly, if you’re experiencing nasal congestion, a decongestant can help shrink your swollen nasal passageways.5
