We enjoy sneezing primarily because of the release of endorphins and the relief from an irritant.
Sneezing, while often inconvenient, can be a surprisingly satisfying experience. This stems from a combination of physiological factors:
-
Endorphin Release: The forceful muscle contractions involved in a sneeze (including chest and stomach muscles) can trigger the release of endorphins, which are natural pain relievers and mood boosters. This is similar to the feeling of relief after tightly squeezing and then relaxing a muscle. The post-sneeze relaxation provides a sense of pleasure.
-
Relief of Irritation: Sneezing is a reflex designed to expel irritants from the nasal passages. The feeling of something "tickling" or irritating your nose can be quite bothersome. The act of sneezing violently removes this irritant, providing immediate relief. This relief is intrinsically rewarding. Just like scratching an itch, sneezing offers a resolution to an unpleasant sensation.
-
Parasympathetic Rebound: Although a bit more complex, the autonomic nervous system plays a role. Sneezing involves a surge of sympathetic activity, followed by a "rebound" of parasympathetic activity. This rebound can lead to a brief period of relaxation and mild euphoria in some individuals.
In summary, the enjoyable sensation associated with sneezing results from the release of endorphins, the relief from irritation, and a potential autonomic rebound effect. These factors combine to create a temporary feeling of well-being.
