Emotional Labor

”1. The smile exercise

Simple and straightforward, this incremental exercise in smiling practice improves the facial muscles that control your smile, which will give you greater control over your happy expressions. Start by sitting or standing in front of a mirror, whichever is more comfortable, with your face and lips in a relaxed state.

1. Stretch the corners of your mouth laterally (to the sides) while keeping your lips together; hold for 10 seconds.

2. Expand the lateral stretch and part your lips to expose the edge of your teeth; hold for 10 seconds.

3. Stretch further laterally and expose about half of your teeth; hold for ten seconds.

4. Smile as wide and hard as you can, with all your teeth showing; hold for ten seconds.

5. Repeat steps 3, 2, and 1 to reverse the smile gradually.

For additional exercise, you can go through all of the above steps, using your index fingers to stretch the corners of your mouth and create the different smiles.”-
