True! That's why when you cry, you sniffle also.
Yes, tear ducts are connected to the sinuses through a system of small passages. The tear ducts drain tears from the eyes into the nasal cavity, specifically through the nasolacrimal duct, which empties into the inferior nasal meatus. This connection is why your nose may run when you cry, as excess tears can flow into the nasal passages.
It's not exactly normal for this to happen, but it's not unheard of either. Your nose and tear ducts are connected so during a nose bleed if you lean your head back some of the blood can go back upwards and come out of your tear ducts. It's also possible to breathe through your tear ducts, and you may notice when you cry your nose runs in part because of tears leaking down to the nose.
When air comes out of your tear ducts during nose blowing, it indicates a connection between the tear ducts and nasal cavity, possibly due to a tear duct blockage or nasal congestion. This condition can be uncomfortable but is usually not a serious concern. If persistent or bothersome, it's best to consult a doctor for further evaluation.
Nasolacrimal is the medical term meaning pertaining to the nose and tear ducts.
Tear ducts leak water, bodies are 90% water, water excreted is salty, the brain sends a message to the tear ducts when you are sad and the tear ducts clean themselves by releasing the fluids
Tearing when pulling out nose hair occurs because the nasal passages are closely connected to the tear ducts. The mucous membranes in the nose are sensitive, and pulling out hair can trigger a reflex response, leading to the production of tears. Additionally, the pain or irritation from the hair removal can stimulate the autonomic nervous system, which further contributes to tearing.
Nose piercings generally hurt regardless of the thickness of the cartilage, due to the fact the tear ducts are connected to the nose too. But it may take a bit longer, than someone who has thin cartilage, since the piercer has to push through a few more layers.
A riboflavin (vitamin B2) deficiency is often the cause of bocked tear ducts: try taking a high potency B vitamin formula (B-100); some vitamin A & D might help clear up any infection as well.
