OHA is a pebble designed to soothe anxious symptoms such as hyperventilation and lack of focus. It is based on the concept of repetitive motions, which biologically have a calming affect on the brain. The textures and movements of the pebble activate a sensory awareness through Grounding. The Grounding technique is a form of mindfulness, which is used to reorient a person to the here-and-now. This is highly beneficial in calming anxiety,

as it refrains one from getting lost in the worrisome and negative thoughts and brings them back to the

present moment.
