Steps to Understand
Why People Stick Out Their Tongues

They’re focusing deeply. Often, individuals unconsciously extend their tongues when engrossed in a task or deep in thought. This automatic response occurs without their awareness. Psychologists suggest that this action may enhance brain activity related to communication, facilitating clearer thinking and problem-solving.
- Children exhibit this behavior more frequently, as adults tend to curb such actions over time to align with societal norms.

They’re being playful. Frequently, someone will stick out their tongue when they’re in a lighthearted mood. This gesture often follows a joke, a funny remark, or a humorous action, serving as a way to convey, “I’m just having fun!”

They’re showing interest. If someone attractive playfully sticks out their tongue at you, accompanied by a wink or a smile, it’s likely a flirtatious move. This teasing gesture is their way of showing interest in a fun and engaging manner.
- This is usually a harmless and flirtatious act, often following a compliment or a playful remark. However, it can also carry a more suggestive tone when paired with a risqué comment.

They’re trying to charm you. A child or someone you admire might stick out their tongue to appear endearing or to win your affection. This gesture typically follows a kind or innocent statement designed to bring a smile to your face.

They’re being disrespectful. In certain situations, someone might stick out their tongue to mock or provoke you. This gesture is intended to irritate or unsettle you. If someone is being unkind or hostile and then sticks out their tongue, it’s likely done with ill intent.

They’re provoking you. Sticking out the tongue can be interpreted as either playful or spiteful. For instance, a romantic interest playfully sticking out their tongue with a cute facial expression might be teasing you affectionately, especially when combined with a flirtatious remark. On the other hand, a child sticking out their tongue after misbehaving or making a rude comment is likely trying to annoy you, akin to saying, “Nana nana boo boo!”

They’re acknowledging you. In Tibetan culture, extending the tongue is a traditional form of greeting or showing respect. This practice originated in the 9th century during the rule of King Lang Darma, a tyrant known for his black tongue. Fearing his reincarnation, Tibetans began sticking out their tongues to prove they were not the reborn king.
Why do infants stick out their tongues?

Babies often stick out their tongues when they’re hungry or playful. If you notice a baby protruding their tongue, there’s no need for concern—this is a natural behavior. Typically, a baby will stick out their tongue for one of these reasons:
- They’re copying you. Babies may stick out their tongues in response to seeing you do the same, as they explore imitation through sounds and movements.
- They’re hungry. Repeated tongue protrusion or mouth movements can indicate hunger. Look for additional hunger cues, such as bringing their hands to their mouth or reaching for food.
- They’re teething. A baby sticking out their tongue might be exploring the sensation of emerging teeth. Other signs of teething include irritability.
- They’re breathing. If a baby has difficulty breathing through their nose, they may stick out their tongue while mouth-breathing. This could signal congestion, enlarged tonsils, or a nasal blockage. Consult a doctor if breathing issues persist.
- They have a tongue-tie. Frequent tongue protrusion might indicate ankyloglossia, where the tissue under the tongue is unusually short. Seek medical advice if you suspect this condition.
- They have macroglossia. Macroglossia, characterized by an enlarged tongue, can be associated with conditions like Down syndrome or hypothyroidism. Consult a doctor if you notice this in your baby.
- They have micrognathia. Micrognathia, a condition involving a smaller-than-normal jaw, may occur in babies with Pierre Robin Sequence or cleft palate. Contact a healthcare provider if you suspect this issue.
