Nighttime drooling — medically called Nocturnal sialorrhea — is common, but persistent cases can signal more than a harmless sleep quirk. It may be linked to snoring, reflux, swallowing issues, or breathing problems that interfere with normal saliva control. While occasional drooling isn’t unusual, experts say frequent episodes are worth checking because untreated causes can lead to irritation or, in rare cases, aspiration. Paying attention early helps rule out underlying issues and keeps small problems from becoming bigger ones.
