Mewing is a technique that involves proper tongue posture, aiming to potentially influence jawline and facial structure. The practice, named after Dr. John Mew, suggests that resting the entire tongue against the roof of the mouth while keeping the lips closed and teeth lightly touching can improve facial aesthetics and respiratory health. Consistency is key, and practitioners should ensure their tongue is pressed firmly and completely against the palate, not just the tip, to potentially see changes over time. It's also recommended to maintain good overall posture and engage in regular jaw exercises to complement the effects of mewing. Mewing 101 :>
