Can Dehydration Cause Sore Throat? 

Yes, it can. Moreover, sore throat from dehydration might just be a symptom that you haven't had enough to drink. When you're dehydrated, your body produces less saliva, which helps to keep your mouth and throat wet.

Without much moisture, your throat gets dry, and once it does, it gets vulnerable to becoming quite sore.

However, there are a few other reasons for developing sore throat dehydration. They are:

Sleeping with your mouth open:

If you have a dry or quite a bit sore every morning, it's possible that you sleep with your mouth open, which could lead to dehydration or sore throat. The saliva that ordinarily keeps your mouth and throat wet gets dried up by the air.

  • Snoring
  • Weariness throughout the day

Snoring might indicate obstructive sleep apnea, a disorder in which your breathing repeatedly stops throughout the night.

Mouth breathing may be caused by congestion from a cold or persistent allergy, as well as an issue with your nasal passages, such as a deviated septum.

If you have obstructive sleep apnea, your doctor may recommend an oral device to realign your jaw or CPAP treatment to maintain air moving into your airways throughout the night.


Sore throat dehydration can be caused by colds. Colds are a frequent ailment caused by a variety of viruses. Your throat may become dry and itchy because of an illness. You may also experience the following symptoms:

  • Runny, clogged nose
  • Sneezing
  • Cough
  • Body pains
  • Mild fever

Most colds only last a few days. Antibiotics are ineffective against colds because they only kill bacteria, not viruses.

Try these home treatments to help you feel better as your body recovers from the cold:

  • To treat a sore throat and body pains, use an over-the-counter pain medicine such as acetaminophen (Tylenol) or ibuprofen (Advil).
  • Take a throat lozenge.
  • Warm drinks, such as broth and hot tea, should be consumed.
  • Gargle with a solution of 1/2 teaspoon salt and warm water.
  • To ease a stuffy nose, use a decongestant nasal spray. Here is where you can get one.
  • Drink plenty of water to avoid dehydration and moisten your mouth and throat.
  • Make sure you get enough rest.
  • To wet the air in your room, turn on a humidifier.


The flu is a respiratory infection. The flu is caused by a virus, much like a cold. However, flu symptoms are more severe than cold symptoms.

You may have the following symptoms in addition to sore throat and dehydration:

  • Fever
  • Chills
  • Cough
  • Stuffed nose, runny nose, muscular pains, headaches, tiredness, vomiting, and diarrhea

The flu may cause significant consequences, particularly in young children, the elderly, and those with chronic medical issues or compromised immune systems. Sore throat dehydration may just be a minor symptom compared to other symptoms that could come with the flu.

Pneumonia, bronchitis, sinus infections, ear infections, and asthma episodes in persons who already have asthma are all complications of the flu.

Antiviral medications may help you feel better faster and lessen the length of time you're ill with the flu. However, for these medications to function, you must take them within 48 hours after the onset of your symptoms.

  • Take a throat lozenge.
  • Gargle with a solution of 1/2 teaspoon salt and warm water.
  • To reduce your temperature and treat body pains, use an over-the-counter pain medicine such as ibuprofen (Advil) or acetaminophen (Tylenol).
  • Drink warm liquids like tea or broth.

What Does It Feel Like to Have a Dehydrated Throat?

A rough, scratchy, or itchy sensation in the throat is a sign of a dry throat. Environmental factors, dehydration, allergies, and minor respiratory infections are the most frequent reasons for a dry throat, which are typically remedied at home.

It's possible that it's the outcome of an underlying sickness in certain circumstances, and sore throat dehydration may just be one of the symptoms.

If you have a painful throat or a dry mouth every morning, it's possible that you're sleeping with your mouth open. The saliva that ordinarily keeps your mouth and throat wet get dried up by the air.

More so, because of the constant vibration in your throat when you snore, you could wake up with a sore throat regularly. Mouth breathing can lead to a sore throat, especially while sleeping.

This could result in sore throat and dehydration.

Why Does My Throat Still Feel Dry After Drinking Water? 

Mucous membranes that have dried out are the most prevalent cause of dry and sore throat. The throat, the respiratory and digestive systems, and other places are all lined with this protective layer.

Exercise, sleeping with your mouth open, breathing through your mouth, living in a dry atmosphere, and not drinking enough fluids may all cause the throat to dry out.

Tobacco or marijuana use, frequent coughing, allergies, pharmaceutical side effects, and, in rare circumstances, throat and esophageal malignancies may all cause dry throat.

If you've done everything in this piece and still aren't feeling better, it's best you consult your doctor. Sore throat dehydration may also be a symptom of an ailment that needs medical attention.
