Right now, as you are, make a frown, your forehead wrinkles your brows come together. Now notice whether the rest of your body responded? Do it again…what happens to your shoulders, neck, hips. Does it feel like gripping or pressure, what about your breath, are you breathing? This is so interesting to discover, and I feel it could occur even with a slight squint or frown; sensations of heaviness, tightness, lack of oxygen.
Now, I would like you to smile, even think of something that pleases you, a joke, etc; and I found even it I just make a smile without a perceived experience I begin to experience a pleasant feeling, something I love, a joke. Now notice how your eyes smile too and there is an upturn, your cheeks lift, could this be an “temporary face lift!!” What is happening in your shoulders, your whole statute, do you feel all over lift, a lightness? And your breath may come out as a sigh, or reflects in your body as whole body breathing.
I discovered this as I go up the stairs, if I smile, I transcend the steps with a springyness a lightness, I’m going up in space physically and if I add a smile, I actually go up through my whole stature or you could say posture.
Oh, and another cool thing, a smile is contagious, like a yawn!
