What You Should (and Shouldn’t) Drink to Stay Hydrated When You’re Sick

the science of smiles best dentist pasadena caAs a health professional, I’m always concerned about my patients’ overall wellbeing. Sure, dental health is my priority. But, total body health and wellness is important too!

So, we approach cold and flu season I thought I’d touch on the important topic of hydration. We’ve always been told to make sure to get plenty of rest and drink plenty of fluids when we’re feeling under the weather. But why is it so important? And, what exactly should you be drinking when you’re feeling off?

It’s important to stay hydrated every day, whether you’re sick or not. Dehydration during an illness can make your symptoms worse, though. This could lead to sinus dryness, pressure, and even nausea and vomiting. If you spike a fever, you can dehydrate yourself even faster than normal. It’s important to replace the fluids you’re losing with new ones.

What to Drink?

Here’s what to reach for when you’re sick:

  • Water – This one may seem obvious. Consuming plenty of water will help you replace what you’re losing. And, it doesn’t contain any tooth-harmful additives.
  • Tea – Since tea contains water, it will help you stay hydrated while also providing additional benefits. Many used to think that tea dehydrated you, but that myth has been debunked. Green tea, for example, can inhibit unfriendly mouth bacteria.
  • Soups/Broths –These are a good way to keep food down while sick. Water-based soups and broths will help hydrate you while the heat will reduce any mucus buildup.

What Drinks to Avoid?

  • Sugary drinks Sports drinks and tooth decay go together like peanut butter and jelly. Beverages like sports drinks and fruit juices can seem like a good choice when you’re sick, but they don’t help with hydration. The added sugar isn’t mouth-friendly and can lead to tooth decay. If you absolutely must consume them, make sure to mix in water and brush your teeth 30 minutes afterward.
  • Alcohol — While there are a few tall-tale alcoholic remedies (we’re looking at you, hot toddy!), drinks containing alcohol should be avoided while sick. Alcohol dehydrates you and can dry out your mucus membranes, leading to more of that gross green goop coming out of your nose. And no one wants that.


Yes, you can over-hydrate yourself. Your body can have so much hydration that it depletes your sodium level. This is known as hyponatremia. Although rare, it can occur if you’re overzealous with your fluid intake.

Don’t let this stop you from hydrating while sick. Just use your thirst as a gauge. If you’re thirsty, that’s a sign that your body is looking to replace fluids.
