Doctor's answer:
It seems that the tears secreted by your lacrimal glands, apart from a portion that lubricates the eyes, are drawn through the action of the lacrimal sac via the lacrimal canals and the nasolacrimal duct into the nasal cavity. If the lacrimal drainage system is obstructed, such as due to narrowing, blockage, dysfunction, or inflammation of the lacrimal canals, the tears cannot be expelled normally. Additionally, external cold air stimulation, as well as various physical, chemical stimuli, mechanical factors, etc., can reflexively increase lacrimal gland secretion, causing tears to overflow. If the lacrimal duct is completely blocked, even when sitting indoors, it can also cause tearing.
