Why Does Blowing Your Nose Cause Pressure in Your Eyes?

Blowing your nose can cause air to be pushed towards the eyes?

Hello, Doctor.
I feel a sensation of air rushing towards my eyes when I blow my nose.
Is this because I'm blowing my nose too hard? Previously, I didn't experience this sensation with the same force.
What should I pay attention to?

Hello, this is normal.
The gas should come out from the inner corner of the eye because the nasolacrimal duct is located there, which is the passage for tears to flow into the nose.
Generally, blowing your nose shouldn't cause a spray of gas; it may be that the gas is unable to be expelled completely and promptly through the nostrils, so it comes out from above.
It's not a concern, but it's best to blow your nose a little more gently.

More Info

When you blow your nose, especially with significant force, it can create a sensation of pressure in your eyes. This phenomenon is primarily due to the interconnectedness of the nasal passages and the eyes through the nasolacrimal duct, which drains tears from the eyes into the nasal cavity. Here’s a more detailed explanation of why this occurs and what you should be aware of.

Mechanism of Pressure Sensation
1. Anatomical Connection: The nasolacrimal duct connects the lacrimal sac (which collects tears) to the nasal cavity. When you blow your nose, the increased pressure in the nasal passages can lead to a temporary increase in pressure within the lacrimal sac and, consequently, the eyes. This can create a sensation of fullness or pressure behind the eyes.

2. Sinus Pressure: The sinuses, which are air-filled spaces in the skull located near the eyes, can also contribute to this sensation. If you have sinus congestion or inflammation (sinusitis), blowing your nose can exacerbate the pressure in the sinuses, leading to a feeling of pressure in the eyes.

3. Eustachian Tube Dysfunction: The Eustachian tubes, which connect the middle ear to the back of the throat, can also be affected when you blow your nose. If these tubes become blocked or fail to equalize pressure properly, it can lead to a sensation of pressure in the ears and eyes.

Considerations and Recommendations
- Gentle Blowing: If you notice that blowing your nose causes discomfort or pressure in your eyes, try to blow your nose gently. Forceful blowing can not only create pressure sensations but may also lead to other issues, such as nosebleeds or ear discomfort.

- Hydration and Humidification: Keeping your nasal passages moist can help reduce congestion. Consider using saline nasal sprays or a humidifier, especially in dry environments.

- Allergy Management: If you have allergies that cause nasal congestion, managing these allergies with appropriate medications (antihistamines, nasal corticosteroids) can help reduce the frequency and severity of symptoms.

- Consult a Healthcare Provider: If you frequently experience pressure in your eyes when blowing your nose, or if you have other symptoms such as persistent pain, vision changes, or significant nasal congestion, it may be wise to consult an ear, nose, and throat (ENT) specialist or an ophthalmologist. They can assess for any underlying conditions, such as sinusitis or other issues that may be contributing to your symptoms.

Conclusion
In summary, the sensation of pressure in your eyes when blowing your nose is likely due to the anatomical and physiological connections between your nasal passages and your eyes. While it is usually not a cause for concern, being mindful of how forcefully you blow your nose and taking steps to manage nasal congestion can help alleviate this sensation. If symptoms persist or worsen, seeking medical advice is always a prudent choice.
