Drooling in your sleep is usually harmless, often caused by “sleeping in the wrong position, being overly tired, or having a stuffy nose.” In most cases, it’s temporary and resolves on its own.
However, persistent drooling can signal a deeper issue. Certain neurological disorders may “affect muscle control and lead to excessive saliva production during sleep.” In rare cases, it’s been linked to cancers involving the throat, esophagus, or nervous system, which can disrupt swallowing.
Warning signs include difficulty swallowing, unexplained weight loss, or ongoing throat discomfort. “If drooling is accompanied by” these symptoms, prompt medical attention is important.
Early detection improves treatment outcomes, especially for serious conditions like cancer. Consulting a doctor can rule out dangerous causes and find effective solutions.
While “drooling is usually nothing to worry about,” paying attention to changes ensures you won’t miss your body’s early warnings—because it often whispers before it shouts.
