1. Can Dehydration Cause Sore Throat?

Now, the most reasonable question is how to tell the difference between a sore throat caused by severe dehydration and a strep throat caused by acid reflux swollen lymph nodes, or other reasons.

You will know you are dehydrated 1when your urine is a pale yellow. Also, if you notice tiredness or stiff joints or if you have trouble breathing, you can increase your fluid intake.

On the other hand, common colds, viral infections, Medina2, or bacterial infections can cause sore throats as well. Most probably, they will be accompanied by a muffled voice, a stuffy nose, fever chills, and other symptoms along with a persistent sore throat.

However, in these cases, drinking warm water, gargling with warm salt water, taking throat lozenges3 or any type of home treatment would not be enough to cure the symptoms. See a doctor and use certain medications prescribed by him or her to get rid of the symptoms.

2. Causes of Dehydration:

Dehydration Signs and Symptoms / Dehydration treatment / Dehydration features / Medinaz

Listed below are a few of the reasons that can cause moderate dehydration to severe dehydration:

2.1 Lack of  Fluids-

Sometimes, your body may lack enough fluids. For instance, if you’re sick, don’t drink enough water, sweat a lot, or simply neglect your self-care routine, it can cause dehydration.

2.2. Reduced Saliva-

When you are dehydrated, your body does not have enough water to produce saliva that keeps your mouth, throat, and thoracic cavity4 lubricated and healthy. This leads to a dry mouth and a sore throat.

2.3. Stuffy Nose-

You may breathe through your mouth at night, especially if you have a stuffy nose, perhaps due to blockage in your nasal passages. This can cause quick evaporation of your body fluids and result in dehydration.

2.4. Climate-

The climate of your area greatly affects your fluid intake and thus, influences the hydration level of your body. A warm and humid climate allows for more moist air due to rapid evaporation. This leads to more sweating or perspiration and thus, there is more intake of fluids.

Whereas, in cold and dry climatic conditions, there is hardly any kind of perspiration as the air is devoid of moisture. This creates a diminished urge to drink water. Thus, dry mouths and sore throats are common in winter.

2.5. Certain Medical Conditions-

Certain medical conditions can cause dehydration. A dry mouth can be a result of diabetes, Alzheimer’s disease, Sjogren’s syndrome, and stroke. Sjogren’s syndrome5 (SHOW-grins) is an autoimmune disease that causes the body to attack the glands that produce moisture, especially common in women who have gone through their menopause.

2.6. Talking for a Long Time-

Talking for a long period without any fluid intake can cause dehydration, leading to a dry throat, hoarseness, and trouble swallowing. This is common for public speakers and singers. Thus, they take breaks to drink warm liquids or sip on water, once they are backstage.

2.7. Allergies and Infections-

Allergies and mild respiratory infections can lead to dehydration and sore throats like upper respiratory tract infections (URTIs), usually accompanied by common cold symptoms. The immune system is weakened and it is advisable to call your doctor.

2.8. Cold Drinks-

Consumption of cold drinks, ice cream, or anything too cold can cause sore throat. It is suggested to avoid them in cold winters.

2.9. Physical Activities-

Last but not least, strenuous physical activities like rock climbing, weight lifting, hiking, or any form of physical exercise can cause dehydration.

Cough, hoarseness, or soreness in the roof of the mouth and difficulty with speech are signs of a dehydrated throat.

Also, dry or chapped lips should not only make you reach out for your favorite lip balm but also your bottle of water.
