Is there any link between excessive sniffling when having a runny nose and otitis media? By sniffling I mean propelling thin watery mucus up one's nose into the nasal cavity rather than pulling thick mucus down one's throat.

Where I was brought up, sniffling is strongly frowned upon (almost culturally institutionalized misophonia). Grandparents used to say sniffling can cause otitis media, but I am not able to find any evidence neither for nor against.
