Why Do I Have Watery Eyes and Runny Nose?

Gina Walters



Watery eyes and runny nose are common symptoms that can be triggered by factors like allergies and infections.

It can be very hard to deal with watery eyes and runny nose if you don’t know the cause.

Therefore, understanding the cause is very important for treating the condition effectively. 

In this article, we will look at the causes of watery eyes and runny noses and how to treat them.

Why are my eyes watery and my nose runny

Before understanding the causes, knowing how a runny nose and watery eyes are connected is important.

Rhinorrhea is the medical term used when mucus continuously comes out of your nasal tubes. 

A runny nose is usually followed by red eyes and watery eyes that itch. These symptoms are often the body’s natural defense against foreign objects. 

Watery eyes and a runny nose might be ways for the body to eliminate allergens or foreign particles in the lungs.

Because of this, both of these symptoms usually show up simultaneously and sometimes go away on their own.

What causes watery eyes and runny nose

There are several causes of watery eyes and a runny nose, which can irritate a person.

These symptoms may appear together in an individual due to allergies and infections.

These allergies might occur due to dust, pollen, or other foreign particles. At the same time, the infections may include Sinusitis or viral infections like colds or flu.

Let us take a closer look at all these factors below

Sinusitis: Sinusitis is the inflammation or swelling of the tissue that lines the sinuses, which are typically air-filled structures located within the face.


Most of the time, allergies are blamed for watery eyes and runny nose. A study discovered that allergic rhinitis, or a runny nose, might cause sneezing and nasal congestion.

Myelin, dust, pollen, and pet dander are all allergens that can cause the body to release histamines as a defense

These histamines can cause blood vessels to widen and make more mucus, making your eyes and nose watery. 

Getting tested for specific allergens and taking precautions like using air filters can help you deal with these symptoms better.

Colds and flu, caused by bacterias or viruses, can also make your eyes watery and your nose run. 

Infections make the immune system work harder, which causes swelling, thus enhancing the tears and mucus production. 

Good cleanliness, like washing your hands and staying away from people who are sick, can lower the risk of infection.

Runny nose and watery eyes treatment

The best way to treat watery eyes and a running nose depends on what’s causing them and how bad the symptoms are.

Doctors often prescribe antihistamines when allergies are responsible for watery eyes and runny nose. 

These medicines work well to treat allergies and make symptoms like watery eyes and a runny nose less severe.

Doctors may also give you decongestants and nasal corticosteroids to help with inflammation, a major cause of runny eyes.
