Keep the Hands Busy
If you often touch your face when sitting in the class or waiting for the school bus, try keeping your hands busy with a small object. It can be a gemstone, rubber band, bead bracelet, or ball. Make sure to sanitize and clean the item often to prevent germs from spreading. If you are a creative person, then doodling and knitting can be perfect options to keep the hands engaged. For those who often watch TV, use one hand to massage the other one. [2]
