Eating mucus is the act of extracting nasal mucus with one's finger (rhinotillexis) and the succeeding action of ingesting the mucus from the nose-picking (mucophagy).[1] Nasal mucus is also termed as boogers, snot, bogeys, dried nasal mucus, mucus secretion, and other related terms including comerse los mocos (to eat one's snot).[2]

Mucophagy is a common behavior in children. However, this action is condemned in most cultures and societies which try to prevent development of the habit and attempt to break it if already established. Mucophagy is a source of mockery and entertainment in the media thus confirming the social scorn previously mentioned.


Mucophagy comes with many health risks due to the potential physical destruction resulting from the action of nose picking, and the germs on fingers and in mucus.[1] Picking one's nose can cause upper airway destruction as well as other injuries including nasal septal perforation (a "through-and-through defect" of the cartilage separating the nostrils),[3] and epistaxis (nosebleed). In Andrade and Srihari's aforementioned study, 25% of subjects were ailed by nose bleeds, 17% with nasal infections, and 2% with damage more serious than bleeding.[4] W. Buzina studied the fungal diversity in nasal mucus in 2003. 104 samples were gathered with 331 identifiable strains of fungi and 9 different species per patient.[5]

Possible reasons[edit]

The Obsessive–Compulsive Disorder Association of South Africa collectively concluded that nose picking (and mucophagy) are passing behaviors.[4] Andrade and Srihari studied persons who were more apt to suffer from "habitual and obsessive–compulsive behaviors." They discovered that those with psychotic issues showed correlation between nose picking and self-mutilation motives.[4] Diagnoses have also included passive–aggressive character disorder and schizophrenia.[6]

Mucophagy has also been referred to as a "tension phenomenon" based on children's ability to function in their environment. The different degrees of effectively fitting in socially may indicate psychiatric disorders or developmental stress reactions. However, most mothers view these habits as pathological issues.[7] Moreover, Andrade and Srihari cited a study performed by Sidney Tarachow of the State University of New York which reported that people who ate their boogers found them "tasty."[4]
