Nenänukumista

Nenänukumista, sometimes referred to as "nose-swallowing," is a phenomenon where an individual unintentionally inhales a portion of their own nasal mucus or secretions. This is a common, albeit often unacknowledged, bodily function. The mucus is produced by the nasal cavity to trap dust, allergens, and pathogens, and a small amount can be swallowed without conscious effort.

This process typically occurs passively as part of normal breathing and swallowing reflexes. The mucus moves down the back of the throat and is then swallowed along with saliva. While it may seem unpleasant, it is a natural way for the body to clear the nasal passages and is not harmful. In most cases, individuals are unaware that it is happening.

The amount of mucus produced can vary depending on factors such as allergies, illness, or environmental conditions. Increased mucus production might lead to a slightly higher frequency of this unintentional swallowing. While some people may find the concept aversive, it is a widely experienced physiological event. There are no known adverse health consequences associated with typical nenänukumista.
