I just love this! A perfect example of the DBT Distress Tolerance skill called Half-smile. A half-smile is slightly up-turned lips with a relaxed face. By having a small half-smile on your face, you are less tense in your face, neck, and shoulders. Try to adopt a serene facial expression, even when you aren't out in public. Your body communicates to your mind and this skill has been shown to improve your mood.
