Abortive Nasal Expulsion Events: The Frustrated Sneeze as a Documented Clinical Phenomenon

The sneeze reflex is a stereotyped, phylogenetically ancient motor program consisting of deep inspiration, glottal closure, and forceful expiration, serving the adaptive function of clearing nasal irritants (Songu & Cingi, 2009). This reflex, when initiated, typically completes within seconds. In a clinically under-studied subset of initiation events, however, the reflex arc is triggered but not completed — the anticipatory sensory buildup occurs, muscular preparation begins, the individual assumes the characteristic pre-sneeze posture and expression, and then the sneeze does not happen. This event — the ANEE — has been described colloquially for centuries but has never been subjected to formal clinical assessment. The present study provides this assessment, treating the frustrated sneeze not as a minor inconvenience but as a neurophysiological failure event with a distinct psychological signature.

Participants.

Two hundred and sixty-one adults (M age = 30.1, SD = 6.8) who experienced an ANEE in the prior 24 hours were recruited via targeted sampling in clinical waiting areas, office lobbies, and one train station where the lighting conditions were, apparently, productive for recruitment. Exclusion criteria included participants who had deliberately looked at a light source to complete the sneeze (n = 43, excluded for successful self-intervention; their strategy was noted and appended as Supplementary Note 1). IRB protocol RP-2024-0198 was approved.

Instruments.

The Frustrated Sneeze Impact Scale (FSIS; 15 items, α = .85) measured affective incompleteness, nasal hyper-awareness duration, distraction from prior task, and facial expression persistence following ANEE. A control group completed full sneezes and reported what they described as immediate resolution and mild satisfaction.

Procedure.

FSIS was administered within 10 minutes of ANEE. Post-event nasal state was tracked for 10 minutes.

Affective Incompleteness.

FSIS affective incompleteness scores were significantly elevated following ANEE compared to completed-sneeze controls, t(259) = 12.6, p < .001, d = 1.56. Ninety-four percent of ANEE participants described the experience as producing a distinct sense of unfinished business.

Recovery Duration.

Mean ANEE recovery time — defined as return to nasal baseline and affective resolution — was 4.2 minutes (SD = 1.8). In 31% of cases, nasal hyper-awareness persisted beyond 6 minutes, constituting what the authors term 'extended ANEE syndrome.'

Task Disruption.

Eighty-one percent of participants reported inability to resume their prior cognitive task immediately following ANEE, with a mean task re-entry time of 3.1 minutes (SD = 1.4).

The 94% affective incompleteness rate confirms that the ANEE is not a trivial event. The sneeze reflex is, evolutionarily, one of the most forceful and complete motor programs in the mammalian repertoire. When it aborts, the organism has prepared for an action that did not occur — a state of motor and affective preparation without discharge that the available literature has not, until this paper, named or measured.

The task re-entry disruption (3.1 minutes) has direct organizational relevance. An employee experiencing an ANEE is not distracted by the sneeze. They are distracted by the absence of the sneeze, which is a more persistent and less socially visible disruption than the sneeze itself would have been.

The photic sneeze reflex — used by 43 excluded participants to complete the aborted event by looking at a light source — represents the most effective current intervention and was, by informal observation during data collection, the fastest recovery mechanism available. Its absence from clinical sneeze management guidelines represents a gap this study recommends addressing.

The Abortive Nasal Expulsion Event produces measurable affective incompleteness, a 4.2-minute recovery arc, and significant cognitive task disruption. It is the only physiological event in this study's dataset where the harm is caused by nothing happening. The authors recommend formal clinical recognition of the ANEE as a distinct respiratory psychology event, the inclusion of photic sneeze induction protocols in clinical management guidelines, and further investigation into what exactly the face thinks it is doing.
