In the third session, a stand-alone device will be provided for home practice HeartMath Freeze Framer. This system analyzes heart rhythms and provides a display sensitive to changes. A colorful game format is used to reward the user for increases in heart rate coherence, which in turn will maximize amplitude of RSA. Participants will be instructed to practice for two 20-minute sessions per day and note in the log included with the HeartMath Freeze Framer instructions whether or not they practiced each day, the length of each practice session, and any questions or observations.
