The human body is full of habits.For example, some people Spout water (or smoke or milk) from their eyes..
But how can some people squirt anomalous fluids out of their eyes, and is it dangerous to their health?
It turns out when someone spouts water from them eye, They are putting pressure on the sac of the nasal bridge (usually where the glasses are placed) that holds the fluid drained from the eyes. This sac is called the lacrimal sac and is part of the lacrimal sac.
The nasolacrimal duct, also called the nasolacrimal duct, is the duct of the lower and upper eyelids that drains fluid from around the eyes. The duct leads to a sac filled with liquid.
Dr. Michel Andreoli, an ophthalmologist at the Northwestern Medicine Regional Medical Group in Illinois and a clinical spokesperson for the American Academy of Ophthalmology, said: “The drainage pipe of the lacrimal duct opens with a small ridge, which looks like the upper and lower eyelids in the inner corner near the nose.”
This liquid is usually drained into the nose and throat. For example, this is why people have a runny nose when they cry.The fluid from the eyes flows through the lacrimal duct into the sac and then nose And throat.
Along the way, there are usually valves that prevent air and liquids from flowing back into your eyes. However, under pressure, some people can squeeze or squeeze out the fluid in the sac or tube.According to a case report published in, it can even make a high-pitched sound Journal of Otolaryngology and Rhinology In 2020.
“Some people can experience reflux or overflow through the lacrimal duct,” Andreoli told Live Science in an email. This overflow is air from the nasal passages that foam the lacrimal duct, or fluid that collects in the lacrimal sac, and may have been pushed out by pressure from sneezing or stuffy nose.
One of the most common ways to apply pressure to the nasal passages is Valsalva maneuver: Take a deep breath, close your mouth, pinch your nose, and then blow for about 10-15 seconds.The pressure from this operation often “pops” ear Apply pressure to the nasal passages.Some people report Squirting milk Also Blow smoke Through this duct when performing this type of pressure rise operation.
The authors of the case report hypothesized that people who can push air or fluid through the lacrimal duct may have an abnormal valve, allowing the fluid to return to the tube and eye.
Thankfully, these party tricks are interesting, but not dangerous, Andreoli says. This is good news because the lacrimal duct system plays an important role in eye health.
“If the lacrimal duct is not functioning, tears can return to the surface of the eye,” Andreoli said. “This can cause watering, redness, irritation, and discomfort.”
